Introduction
Congratulations and thank you for choosing the Furman CN-2400S. We
assure you that your CN-2400S will provide many years of trouble free
operation. The CN-2400S is a 20 Amp Contractor-Grade Surge Protec-
tor and Power Sequencing device equipped with Furman’s exclusive
SmartSequencing™ technology. The Furman CN-2400S features mul-
tiple layers of protection that have been designed to shield your sensitive
analog and digital equipment from AC line hazards. Furman’s SmartSe-
quencing™ technology defines a new level of power management and
control while streamlining installations from start to finish.
Why choose Furman?
At Furman Sound, we have spent the last 30 years quietly obsessing
about professional audio and how to best separate your equipment from
the noise and damage often associated with AC power. Over the years we
have developed a multitude of technologies that have spared countless
devices from certain death and earned us the trust and respect of the
Professional A/V industry. The CN-2400S represents the culmination of
our engineering expertise and leverages more than 30 years of experi-
ence.
Why choose AC power sequencing?
Many pro audio/video installations need audio power amplifiers to activate
last. Our solution is the AC power sequencer. The power sequencer pro-
vides AC power to outlet groups one at a time, thus allowing equipment to
be powered up and down in an orderly fashion by first providing power to
signal processing equipment and then providing power to the amplifiers.
When shutting down the A/V system, a sequencer will turn off the system
in the reverse order, hence the amps will be turned off first, and then the
signal processing equipment will be turned off last.
This is necessary because, as most sound reinforcement professionals
know, the majority of equipment damage occurs when devices are either
powered up or powered down. Power sequencing allows equipment
to power up in sequence and prevent the dreaded “pop”. The “pop”
is a speaker pop associated with on off switching of signal processing
equipment while the audio power amplifiers are energized. If the signal
processing “pop” is amplified sufficiently, the result can damage speaker
components. Because it prevents this unwanted, and often costly, circum-
stance, AC power sequencing is extremely valuable.
Furman Contractor Series equipment also allows sound reinforcement
equipment to be remotely powered up or powered down over a large
distance, not just in the immediate vicinity of the operator. Additionally,
Maintained or Momentary mode contact switching allows the user great
flexibility when controlling the unit from a remote location. A remotely
mounted switch or control pad can be used to sequence equipment on
or off. In addition, Furman Contractor Series remote functions can be
initiated across a room, on-site, or off-site with RS-232 protocol or our
cloud-based BlueBOLT technology.
The CN-2400S SmartSequencer incorporates Furman’s revolutionary
Series Multi-Stage Protection (SMP) circuit with our acclaimed Linear
Filtering Technology (LiFT). In combination, these field tested technologies
comprise, without question, the world’s most advanced power condition-
ing and transient voltage surge suppression anywhere! And, in regards to
Professional A/V, the CN-1800S fulfills many power sequencing require-
ments that have not been easy to achieve in the past. Furman SmartSe-
quencing™ delivers right out of the box! Please review this manual
thoroughly to discover how the CN1800S with SmartSequencing™
delivers professional results.

SmartSequencing™
Furman SmartSequencing™ is a contractor-friendly technology that
makes AC power sequencing easy to employ by non-technical person-
nel. Multiple Furman Contactor Series units can be linked together using
inexpensive two conductor wire, thus creating a vast control system.
Generally, high-priced automation systems are used for large, innovative
installs, yet these control systems seldom combine AC power distribu-
tion, filtering, and protection. Furthermore, many automation systems are
difficult to implement on smaller budgets. SmartSequencing™ provides
the answer right out of the box by offering a simple approach to AC power
management and control. Furman’s newest power sequencing technology
is an end-to-end solution that is operational up to 1000 feet via a non-
polarized, isolated current loop. In situations where power sequencing is
critical, or more than one AC electrical circuit is utilized, wiring Furman
SmartSequencing™ products in series is simple, fast and reliable.
SMP (Series Multi-Stage Protection)
Furman’s SMP surge suppression virtually eliminates service calls and
costly “down time”. Traditional surge suppression circuits sacrifice
themselves when exposed to multiple transient voltage spikes, requiring
your system to be dismantled and your surge suppresser to be repaired.
This does not happen with Furman’s SMP. Damaging transient voltages
are safely absorbed, clamped, and dissipated. Your connected equipment
is protected, while your Furman protects itself! Its unparalleled clamp-
ing voltage is unique to Furman’s SMP. According to UL 1449 Clamping
Level is defined as the amount of voltage that is allowed to pass through
to your equipment when the protection device is subjected to a transient
surge or spike. While other designs offer clamping voltages that clamp
well above 330 Vpk, Furman’s SMP clamps at 188 Vpk, (133 VAC RMS)
even when tested with multiple 6000 Vpk - 3000 Amp surges. This
unprecedented level of protection is only available with Furman’s SMP
technology!
EVS (EXTREME VOLTAGE SHUTDOWN)
Furman’s trusted (EVS) over-voltage circuitry protects against prolonged
over-voltage conditions, such as accidental connections to 208 or 240
VAC or an intermittent loss of neutral. It does so by monitoring the incom-
ing AC voltage. When an unsafe condition is detected, a relay shuts off
the incoming power until the overvoltage condition has been corrected.
The CN-2400S augments the EVS capability with Auto Reset options
allowing the end user to decide if the power should be reinstated, or re-
main off until conditions return to acceptable limits. The Extreme Voltage
Shutdown technology is a tremendous asset.
LIFT (LINEAR FILTERING TECHNOLOGY)
Unfortunately, traditional AC power conditioners have been designed
under unrealistic laboratory conditions. Professional audio/video compo-
nents are constantly bombarded by electromagnetic interference (EMI)
and radio frequency interference (RFI) via their AC power source. Prior
technologies, whether they were multiple-pole or conventional series-
mode filters, could actually harm audio and video performance more than
they help, due to the resonant peaking of their antiquated, non-linear de-
signs. Under certain conditions, these designs can actually add more than
10 dB of noise to the incoming AC line! Worse still, AC noise and ground
contamination frequently causes system reboots, sync issues and even
data loss. LiFT takes a different approach, ensuring optimal performance
through Furman’s linear AC noise filtering with no ground contamination.

Security and Safety
The CN2400S is adaptable to most common installation requests and
requirements. An ON/OFF key switch prevents operation from unau-
thorized personnel and removable security covers help to discourage
tampering. The RS-232 DE-9 communications port can be defeated by
the key switch. Furthermore, there are Forced Off inputs and selectable
DIP Switch settings for connecting to alarm systems, thus providing an
immediate power shutdown in compliance with many fire ordinances. The
combinations of features cover many needs for a wide variety of client
concerns.
Additional Features
The CN2400S Power Sequencer is equipped with eight 120V rear panel
outlets on four duplexes and a single front panel convenience outlet,
all filtered and protected with Furman technology. The unit has three
unswitched outlets that provide constant power under safe utility condi-
tions. Rear panel outlets are divided into four banks: one bank with two
unswitched outlets and three banks are sequenced at two outlets per
bank. A related dry contact is coupled with the “Delay Bank 3” bank; to-
gether both can offer a delay up to seven minutes. Features also include
10 LED indicators to aid in tracking conditions such as power, protection,
sequencing and communication. And naturally, the CN-2400S Contractor

SmartSequencing™ 101
Note: A pair of wires between the Primary OUT terminals of one
sequencer and the Secondary IN terminals of a second sequencer is
all that is required. Which terminals are used at the IN port or the OUT
port does NOT matter; the wiring scheme is polarity independent. Please
remember, even non-technical personnel can achieve professional results
with SmartSequencing™. Two wire runs connecting two or more units
create a SmartSequencing chain.
Furman SmartSequencing™ products can be connected end-to-end
to form a chain. Each Contractor Series unit has two communication
ports (OUT and IN) divided into 4 terminals, responsible for full-duplex
transmissions via two bi-directional current loops. The messages com-
municated are in the form of ASCII character strings made more efficient
by utilizing a High-Level Data Link Control. The first SmartSequencer in a
chain is termed the “Primary” or “Primary Unit”; it controls the “other se-
quencers” in the chain. The “other sequencers” are termed “Secondary”
or “Secondary Units”. The Primary Unit only has one active current loop,
because the Primary Unit only has one Secondary sequencer attached
to it. Once again, when sequencers are attached with SmartSequencing,
the first sequencer in the chain is termed the Primary Unit and all the
subsequent sequencers in the chain are termed Secondary Units. And
so the chain continues as additional Secondary Units are attached, OUT
to IN, OUT to IN, OUT to IN, etc. A pair of wires between the Primary OUT
terminals and the Secondary IN terminals is all that is required to create a
continuous SmartSequencing chain.
A Furman SmartSequencing™ chain transmits a message as follows: A
Primary Unit communicates to the first Secondary Unit downstream, by
sending commands out of its Primary OUT terminals to the Secondary
IN terminals of the first Secondary Unit. If there is a second Secondary
Unit in the chain, the first Secondary Unit communicates to the second
Secondary Unit, using its Primary OUT terminals to the second Secondary
Unit’s Secondary IN terminals. This continues down the sequence chain
until the last Secondary Unit. The last Secondary Unit will receive com-
mands into its Secondary IN terminal port but will not use its Primary OUT
terminal port (because there are no Secondary Units after it). Please see
figure to the left:
SmartSequencing™ commands between units are always accepted
when continuity exists, however SmartSequencing commands that control
the outlets are not always allowed. There are two considerations for de-
ciding whether SmartSequencing control commands are allowed: one, the
state of the other CN-1800S functions (i.e: Key Switch, Start Sequence
Push Button, and Remote terminals e.g. Force Off); and two, whether the
Sequencer is configured as a Primary or a Secondary unit.
The Primary Unit has an active DE-9 RS-232 port that can be used to
communicate with a local RS-232 control system or an Ethernet Blue-
BOLT adaptor. When a SmartSequencer is selected as a Secondary Unit
(DIP Switch position 8 is DOWN or OFF), the unit’s RS-232 port is deacti-
vated. The Key Switch and Force Off function will also defeat the RS-232
port functions regardless of the units Primary or Secondary status.
Additional SmartSequencing™ information is available throughout this
instruction manual. More information on SmartSequencing™ can be
found at our contractor website www.furmancontractor.com. Details such
as firmware updates, Quick Start diagrams, etc., can also be found at the
website.

Start Sequence Push Button
The Start Sequence button can be used for sequencing power up or
power down. This button is located at the left side of the panel. The
START SEQUENCE pushbutton is there to initiate local operation when
the key switch is set to REMOTE. Please note, setting the key switch to
ON defeats operation of the START SEQUENCE pushbutton, keeping in
mind that both the key switch and the START SEQUENCE button operate
in either Maintained or Momentary mode (DIP Switch position 7). If a
number of units are linked via SmartSequencing, or via Remote Terminal,
and unit drops out of sync, press and hold the START SEQUENCE button
for several seconds; this will initiate a re-sync.

Connection Status Lights
Each multi-color Connection Status Light provides information on the CN-
2400S’ communication links. There are three LEDs, labeled PRIMARY
and SECONDARY LINK and ETHERNET that make up the Connection
Status Light subsystem. The top two LEDs are associated with the
SmartSequencer link system and can illuminate Red, Green, or Amber.
The Bottom LED, labeled ETHERNET, indicates the status of a remote con-
nection. When a number of CN-2400S are connected together via their
SmartSequencer link ports, the top two LEDs will illuminate Green and
occasionally blink as messages are passed between units. The ETHER-
NET LED will illuminate Green when the CN-2400S is communicating
with an RS232 to BlueBolt adapter.
SmartSequencing Note: When there are two or more SmartSequencer
units chained in series, a slowly blinking Green Primary Link LED interval
identifies the Primary Unit. Furthermore, a SmartSequencer displaying a
solid Green Primary Link LED would indicate the unit is the last Second-
ary in the chain. Secondary Units in the middle of the chain will display
both a solid Green Primary Link LED and a solid Green Secondary Link
LED. The Connection Status Link Indicators will flash accordingly during
power up and power down and as SmartSequencer messages are sent
between units.
Green LED status is a sign of good communications. If a Contractor Se-
ries unit is used independently (no connections) and the unit is configured
as a Primary Unit (DIP 8, ON or UP), the Primary Link LED will slowly blink
Green at 1 second intervals. If there is a SmartSequencer link connecting
a Primary Unit to a Secondary Unit, the Primary unit will send messages
to the Secondary Unit and the Secondary Link LED will illuminate Green
on the Primary Unit, indicating there is an established communication
link with a the Secondary Unit. On Secondary units (DIP Switch 8, OFF or
DOWN), the Primary Link LED will be Green, indicating there is communi-
cation to a Primary.
Unit has lost communications through Secondary Link to preced-
ing unit’s Primary Link OUT.
Please Note: A slow blinking GREEN PRIMARY LINK LED indicates the
unit is configured as the MAIN Primary unit per DIP Switch 8. (Factory
default).
Please Note: A SECONDARY DEVICE should have a solid green PRIMARY
LINK LED.
PRIMARY LINK – Multi-color LED indicates the condition of communica-
tions between the Secondary Link and the Primary Link of the preceding unit.
Unit is communicating through Secondary Link to preceding
unit’s Primary Link OUT.

The Red Connection status LED can sometimes illuminate briefly if a
message is lost or corrupted on the SmartSequencing link. Unless
the Red LED is continuous, this should be no cause for concern. The
SmartSequencing protocol is robust and redundant. As long as a physical
link is in place, the message will eventually get through.
A continuous Red Connection Status LED indicates that a unit has no
SmartSequencing link connection where the unit has been configured to
expect link communications. This occurs when a Secondary Unit cannot
communicate with surrounding units in a SmartSequencing chain. The
result is that the Secondary Units Primary Link LED may be Red because
the link is broken to a Primary Unit or the Secondary Link LED may be
Red, because the link is broken to a Secondary Unit. This could also
mean that the Secondary Unit sees the Primary Unit, but the Primary Unit
does not see its Secondary.
The Amber LED may be seen upon start up initialization or as communi-
cation ensues between Smart Sequencers. This Amber LED state should
resolve to a Red or Green state. If the amber indication does not resolve,
please contact Furman Support.

Delay Indicators
One DELAY LED is featured for each rear outlet delay stage. Each LED
illuminates Green sequentially as each stage completes, indicating power
is available at the corresponding rear panel bank. If the CN-2400S is
operating under safe power conditions and no utility fault conditions exist,
all three Delay LEDs will remain steadily lit when all outlets ON. Once trig-
gered to power-down, each LED goes off in sequence as its correspond-
ing delay bank is deactivated. Note that the DELAY 3 output and the rear
panel DELAY 3 relay contacts are closely associated. When the indicator
DELAY 3 LED is illuminated, the DELAY 3, Common (C) and Normally
Open (NO) terminals are shorted. When the indicator DELAY 3 LED is off,
the DELAY 3, Common (C) and Normally Open (NC) terminals are shorted.
DIP 1, DIP 2, and DIP 3: DIP Time Adjustment
There are three DIP switches assigned to control the time delay interval,
DIP switch positions 1, 2, & 3. The time delay, or “dwell time” between
consecutive duplexes is the same whether the CN-2400S is sequenc-
ing ON or OFF. DIP 1 adds 1 to the minute maximum time delay, DIP 2
adds 2 minutes and DIP 3 adds 4 minutes. Note: These time delays are
cumulative. If all three DIP switches are in the UP position, the maximum
allowable time delay will be 7minutes, i.e. 1min+2min+4min=7min. The
factory default setting is DIP 1 ON or UP, and DIP 2 and 3 are OFF or
DOWN. You can set these switches in any position you like to achieve
your preferred time delay.
Delay Adjustment
In order to precisely dial in your preferred sequence dwell time, it is nec-
essary to set the Time Delay Adjustment (DLY ADJ) located next to the DIP
Switch. If this potentiometer is turned to its 100% value (fully clockwise),
then the time delay will be equal to the maximum time delay defined by
DIP switches 1, 2, and 3. If the potentiometer is in the 12:00 o’clock po-
sition (50%), then the time delay will be 50% of the maximum time delay
interval defined by the setting of DIP Switch positions 1,2 & 3. If all three
DIP switches are off, and the potentiometer is turned completely counter-
clockwise, the time delay is miminal. The Delay Adjustment potentiometer
comes factory-set at 50%, the 12 o’clock position.
Example: If the DIP Switches are set to a 6 minute maximum delay
and the potentiometer is set to its 50% setting, then the delay interval
between sequenced banks will be 3 minutes. (DIP 1 OFF or DOWN, DIP 2
and DIP 3 ON or UP) x .50 = 6 minutes x .50 = 3 minutes.

DIP Switch and Delay Adjustment
The DIP Switch is found at the center of the front panel, under the “F”
logo Security Cover. You will need to remove the cover by removing the
two M3 screws to gain access to the DIP switch. The DIP Switch is used
to set various sequencer options. It is also used in combination with the
DLY ADJ pot to set range intervals for the SWITCHED banks. The time DIP
switch settings are ON in the UP position and OFF in the DOWN position.

DIP 4, DIP 5, DIP 6, and DIP 7:
Remote Mode Trigger Settings
DIP Switch position 4 is used to define how the CN-2400S will implement
its FORCE OFF feature. FORCE OFF is a safety feature that is designed to
cut AC power to all outlets instantaneously. Many municipalities require
this feature as a means of disabling equipment in the presence of fire
or alarm. The FORCE OFF inputs are the two uppermost poles on Barrier
Strip 3. The FORCE OFF inputs can be used with a momentary or main-
tained dry contact in either a Normally Open or Normally Closed state.
The factory default position is DIP 4 ON or UP, or (NO) Normally Open. In
this configuration, the FORCE OFF will be triggered when the FORCE OFF
pins are shorted. If DIP Switch position #4 is on (DIP 4 OFF or DOWN)
the FORCE OFF pins must remain shorted for normal operation. In this
configuration, the FORCE OFF will be triggered when the short between
the FORCE OFF pins is removed.
If a FORCE OFF occurs, the power to all outputs will be immediately dis-
abled and the DELAY LEDs will blink together. To recover from a FORCE
OFF condition, the CN-2400S or all units in the sequencing chain must
be sequenced off locally, via the Key Switch or Start Sequence pushbut-
ton. Once reset, operations will resume normally. DIP 4 has priority over

DIP 5, DIP 6, and DIP 7 settings. Information found under the following
sections DIP 5, DIP 6, and DIP 7 explain typical remote switch operations.
The use of DIP 4 may or may not be a consideration at every install, yet it
may be vital with regards to safety compliance. The FORCE OFF feature is
always active, despite the fact sometimes it is in a forgotten state of op-
eration. And again, the DIP 4 factory-set position is Up, or (NO) Normally
Open; in order not to disrupt other sequencer functions when emergency
systems are not required.
DIP 5 (+12V, ON OFF) and DIP 6 (GND ON) are used in special situations,
where the standard Contractor Series factory-set remote options are not
preferred. For instance, where a newly remodeled location has an existing
remote key switch different from a Furman remote key switch design; the
mechanics of key switch are the reverse. Yet it would be advantageous
to use the existing key switch, since many personnel already have keys.
DIP 5 (+12V, ON OFF) and DIP 6 (GND ON) could possibly address such
situations. Please feel free to contact Furman, if further assistance is
necessary.
DIP 7 is used to set the remote switching preference. The CN-2400S
can be set to a Maintained Mode (DIP 7 OFF or DOWN) or a Momentary
Mode (DIP 7 ON or UP) dependent upon the chosen method of remote
switching. A Maintained switch method stays open until switched, and
then remains closed until switched again (such as toggle switches, e.g.
Furman RS-1 key lock switch).The Momentary switch method is normally
open and stays closed only as long as the button is depressed (such
as pushbutton switches, similar to the Furman RS-2 security switch).
Momentary Mode does offer an advantage over Maintained Mode when
multiple remote switching locations are desired. Due to technical flexibil-
ity, Momentary switching easily adapts when implemented with more than
one remote switch. However, it is often thought Maintained switching is
more stable, truly shunting control voltages when actuated. DIP 5 and DIP
6 offer additional methods of applying Maintained switching. Regardless
of which switching method is chosen, when changing DIP 4, DIP 5, DIP 6,
or DIP 7, it is required to reset the AC power to the unit.
The CN-2400S has one Momentary Mode of operation (DIP 7 ON or UP),
which is also compatible with Furman Legacy products. As suggested,
when more than one remote switching location is required, momentary
switches offer an advantage. In addition to this benefit, multiple Primary
units set to Momentary Mode can be interfaced together using the
Remote Pole contacts +12V, REM and GND, wired in parallel pole to
pole. No one unit is considered the Primary Unit, yet any unit can act as
one. The multiple units’ delay cycle would initiate at the same time, in
combination with each other; in other words, the units would all start at
once and all initiate a cycle down at once, once any Momentary switch
(button) is pushed (including Remote Momentary switches). As men-
tioned, multiple momentary remote contacts should be used if more than
one remote power up location is desired. If units by chance, drop out of
sync, simply press and hold down the Start Sequence button for several
seconds to re-sync. The wiring of multiple Primary Units in parallel via the
Remote Pole contacts is a Furman legacy operation.

In addition, it should be noted, multiple Primary Units, in Momentary
Mode, could be utilized in a complex SmartSequencing chain. The chal-
lenge is having each Momentary Primary controlling an isolated Second-
ary SmartSequencing chain. Once more, any Primary Start Sequence
button could initiate a cycle up or cycle down; keeping in mind this
sophisticated operation is only possible using the Remote Pole contacts of
Momentary Mode Primary units; and then of course, using the SmartSe-
quencing ports for the Secondary chain. As previously stated, the front
panel Start Sequence pushbutton may be used in conjunction with one or
more Remote Momentary switches connected to a Primary Remote Pole
terminal strip. SmartSequencers set in Momentary Mode have optional
possibilities.
The DIP 7 factory default position is Maintained Mode. Maintained switch-
es are generally most convenient when there is only one remote location.
It is important to note, SmartSequencing units also come factory-set
for simple Maintained On operation (DIP 5 OFF or DOWN, DIP 6 OFF or
DOWN, DIP 7 OFF or DOWN), as opposed to Maintained Off. Maintained
Off is a state whereby a device is OFF until a maintained closure forces it
ON. Maintained On is the opposite and no “shorted” contact is necessary,
the device is ON until a remote contact is shorted. And besides the one
momentary mode, the CN-2400S actually has many maintained contact
switching solutions. As mentioned previously, two maintained functions
are reserved to the FORCE OFF safety setting DIP 4, which has prece-
dence over DIP 7. Below are three typical Remote Switch Maintained
Modes of operation with regard to DIP 5, DIP 6, and DIP 7:
Maintained On (factory default)
REM to +12V = OFF
Setting DIP 5 OFF or DOWN, DIP 6 OFF or DOWN, DIP 7 OFF or DOWN,
the dry contact connection across the REM terminal to the +12V terminal
initiates an OFF sequence. Disconnecting initiates an ON sequence. If
the cable run is long, it is recommended that the REM wire be tied to the
SmartSequencer’s GND terminal during ON operation rather than leaving
it floating. This will require the use of a third conductor and a double-
throw switch.
Maintained Off
REM to +12V = ON
Setting DIP 5 ON or UP, DIP 6 OFF or DOWN, DIP 7 OFF or DOWN, the
dry contact connection across the REM terminal to the +12V terminal
initiates an ON sequence. Disconnecting initiates an OFF sequence. If
the cable run is long, it is recommended that the REM wire be tied to the
SmartSequencer’s GND terminal during OFF operation rather than leaving
it floating.
Maintained Off (option 2)
REM to GND = ON
Setting DIP 5 OFF or DOWN, DIP 6 ON or UP, DIP 7 OFF or DOWN, the dry
contact connection across the REM terminal to the GND terminal initiates
an ON sequence. Disconnecting initiates an OFF.
DIP Switch position 8 determines the unit’s role in the SmartSequenc-
ing™ hierarchy. If DIP Switch 8 is in the UP or ON position, the unit is set
as the Primary Sequencer. If DIP Switch 8 is in the OFF or DOWN posi-
tion, the CN-2400S will operate as a Secondary Sequencer. In an array
of sequencers connected via SmartLink, there can be only one Primary
Sequencer, and multiple (up to 99) Secondary Sequencers. A Primary Se-
quencer sends commands to a Secondary Unit. Please remember, a pair
of conductors between the Primary OUT terminals and the Secondary IN
terminals is all that is required. Which terminals are used at the IN port
or the OUT port does NOT matter, the wiring scheme is indiscriminate.
Furthermore, the Primary Sequencer has an active DE-9 RS-232 port
that can be used to communicate with a local RS-232 control system or
an Ethernet BlueBOLT adaptor. When a SmartSequencer is selected as a
Secondary Unit (DIP 8 Down or OFF), the unit’s RS-232 port is deacti-
vated. Key Switch and Force Off function will also defeat the RS-232 port
functions regardless of Primary or Secondary distinction. Please refer to
SmartSequencing™ 101 page 6.
DIP Switch position 9 sets the EVS (Extreme Voltage Shutdown) recovery
mode that the CN-2400S will employ. If Auto-Reset has been selected
(DIP Switch position 9 ON or UP), the CN-1800S will attempt to re-set
automatically within 5 seconds after the EVS condition has subsided.. If
Manual Reset has been selected (DIP Switch position 9 is OFF or DOWN)
the CN-2400S will not automatically reinstate power after the EVS condi-
tion has subsided. Instead, the user must use the key switch to clear the
EVS error.
The EVS condition will be triggered if the incoming voltage exceeds 140V,
or falls below 80V. Once the EVS has been triggered, all outlets will be
disabled and the Extreme Voltage LED will illuminate. The EVS reset
behavior will depend on the setting of DIP Switch 9. If the CN-2400S has
been configured for manual reset, an operator must manually turn the
affected unit’s key switch to OFF and then back to REMOTE or ON. Please
note, if there is an underlying wiring fault, EVS triggers may continue to
be encountered. If this is the case, an operator should avoid resetting the
unit without first checking the source of the problem and perhaps chang-
ing the AC source.

EXTREME VOLTAGE:
The EXTREME VOLTAGE LED indicator is normally OFF. The EVS function
is tied to this LED and monitors common AC hazards, such as transients,
wiring faults and accidental connection to 240V. The CN-2400S can
sense voltages so high or so low that operation would be hazardous to
connected equipment. The EVS disables AC power distribution before
damage can occur. The EXTREME VOLTAGE LED will be illuminated Red
if voltage events are below 80 volts or more than 140 volts. The EVS
LED will remain illuminated, and the outlets will be disabled as long as
an out of tolerance condition exists. Once addressed and the EVS event
will be cleared and the CN-2400S will sense the correction and resume
operation. If the EVS feature is triggered, the source voltage must return
to an effective utility specification (90V-130V) and the EVS state must be
cleared. Note: If the CN-2400S DIP Switch position 9 is configured for
auto-reset, the unit should self-reset and clear the state automatically.
Unswitched Outlet
There are three unswitched outlets (one on front, two on back) providing
power at all times when the CN-2400S is plugged in and operating under
normal power conditions. The outlets however, are affected by the EVS
feature. The CN-2400S must have its power recycled to clear the state.
If the EVS feature is triggered, the source voltage must return to within
tolerance (90V-130V) and the EVS state must be cleared. Note: If the
CN-2400S DIP Switch position 9 is configured for auto-reset (DIP 9 is ON
or UP), the unit should self-reset and clear the state automatically. This
outlet is not affected by the FORCE OFF feature.
Security Covers
This CN Series Sequencer comes with Cover Shields to protect against
inadvertent shutdowns and to help prevent against unauthorized system
changes. Security Covers discourage unauthorized personnel from run-
ning or shutting down the CN-2400S Contractor Series SmartSequencer.
Furthermore, the Security Covers ensure the DIP Switch settings will not
be tampered with or adjusted improperly once the unit is installed. The
Cover Shields fasten to fitting positions on the front panel. Please use the
four metric M3 Screws for this purpose. Please remember this important
Contractor Series feature should address many concerns in regards to
security, but each location may need additional security based upon
particular situations.

Circuit Breaker
The CN-2400S has a 20 Amp thermal circuit breaker button which will
pop outward if the amount of current distributed to all loads exceeds
20 Amperes. To emphasize, if the combined current level, drawn by all
devices plugged into all of the unit’s nine outlets, exceeds 20 Amps at
any time, the circuit breaker will “trip”, cutting off power to all connected
devices. If this occurs, the operator must reduce the load by unplugging
one or more devices from the CN-2400S, and reset it. The operator can
reset the circuit breaker by simply pressing in the circuit breakers button.
However, because the safety feature is a thermal breaker, one may have
to wait a few moments after the “trip” occurs for the breaker to cool down
before the breaker will latch back on.

Key Switch
The 3 position key switch functions as a local ON or as a command
bypass. The key switch controls power to the CN-1800S unit’s DELAY
outlets based upon the setting of DIP Switch position 8. For local control,
an ON sequence is initiated by turning the key switch to the ON posi-
tion, and an OFF sequence, by turning the key switch to OFF position.
Note: when turning the key switch to REMOTE, after once turned to ON,
the CN-1800S unit’s SWITCHED outlets will remain on until the START
SEQUENCE button is pushed. In the REMOTE position, the CN-1800S
can accept on/off commands from either the back panel terminals or the
RS-232 data link (COMM port). If the key switch is set back to OFF, this
will initiate a shut down to the SWITCHED outlets. Note: the OFF position
also defeats communication through the rear panel COMM port. The
key switch must be in the ON or REMOTE position for the COMM port to
relay commands. Furthermore, an ON position setting, functions in either
MAINTAINED or MOMENTARY mode (i.e. regardless of DIP Switch
position 7), effectively bypassing all other command functions, except
FORCE OFF or EVS.

Rear Panel Overview
Unswitched Outlet Bank and Power Indicator
This duplex bank provides power at all times when the CN-2400S is
plugged in and operating under normal power conditions. The duplex
however, is protected by the EVS feature. The CN-2400S must have
its power recycled to clear the state. If the EVS feature is triggered, the
source voltage must return to within tolerable conditions (90V-130V) and
the EVS error must be cleared. Note: If the CN-2400S DIP Switch Posi-
tion 9 is ON or UP, the unit should self-reset and clear the state automati-
cally. These outlets, as all outlets on the CN-2400S, feature LiFT filtering.
This duplex is not affected by the FORCE OFF feature and AC power will
continue to be available at the UNSWITCHED duplex even if FORCED OFF
is triggered. A Green LED to the right of this bank indicates AC power is
present.
Delay Banks
The CN-2400S rear panel provides three pairs of SWITCHED outlets.
These switched outlet pairs/duplexes are labeled DELAY 1, DELAY 2 and
DELAY 3. When the unit’s SEQUENCE ON function is initiated, DELAY 1
outlet bank receives power instantly, DELAY 2 outlet bank receives power
0-330 seconds later and DELAY 3 outlet bank receives power 0-330
seconds after DELAY 2 outlet bank is powered. When OFF is initiated, the
sequence order is reversed, with DELAY 3 losing power instantly, DELAY
2 bank losing power 0-330 seconds later and DELAY 1 outlet bank los-
ing power 0-330 seconds after DELAY 2 bank is shut down. The delay
intervals may be altered at the Time Delay Adjustment control pot and DIP
settings 1, 2, & 3. The control pot is adjustable with a screwdriver and
both features are located under the security shield, at the center of the
front panel. The combination of the Time Delay Adjustment and the DIP
setting can up provide up to 7 minutes of delay time.

IMPORTANT, PLEASE READ
Outlets and Plugs:
The CN-2400S unit’s four rear panel outlet pairs are standard 120V,
20A duplex types. These outlets are widely spaced, to accommodate one
bulky plug-mounted “wall wart” power supply in each without covering up
an adjacent outlet. The front panel outlet is limited to 15 Amp use and is
filtered. The CN-2400S also uses a 12AWG 20 Amp line cord.
Setup and Troubleshooting
As discussed at the introduction, in order to prevent expensive repairs to
speaker enclosures, a power sequencer or multiple power sequencers
are employed to coordinate AC power to an A/V system. The amplifiers
receive AC power last when a system is turned on and amps have the
AC power cut before the signal processing is turned off. There are many
applications besides those pro audio applications discussed here and
SmartSequencing opens up many possibilities. In regards to pro audio,
we cover the basics within our documentation, yet this does not mean
that other applications cannot garner the benefits of SmartSequenc-
ing. Security and IT professionals can also benefit from remote power
management and power sequencing. Please feel free to consult a Furman
professional to answer any questions or to address the needs for any
particular installation.
Single Unit Set Up
Basic installation of the CN-2400S is ready to go out of the box. The
default DIP Switch settings should be appropriate for most applications.
Plug amplifiers into DELAY 3 or divide them into two groups and plug
one group through DELAY 2 and the other through DELAY 3. Low level
equipment such as mixers and signal processors should use DELAY 1.
Equipment incorporating special needs such as a DVR or offline UPS units
should use the UNSWITCHED outlets, e.g. equipment that must respond
to wireless remote actuation, such as projector. We suggest keeping the
front panel UNSWITCHED outlet free for equipment that is used temporar-
ily. The Key Switch can be used as the main method of On Off operation
or the Key Switch may be set to Remote and the Start Sequence pushbut-
ton can be used for On Off operation. If the Start Sequence pushbutton is
preferred over the Key Switch, simply do not use the pushbutton’s cover
shield. Once all AC connections have been made, test the set-up and
calibrate the timing range with a small screw driver if necessary. Then
secure the Matrix’s cover shield back into place.
Breaker Overload
The overall current capacity of the CN-2400S is 20 Amps. This refers
to the combined steady-state current drawn by all devices plugged into
all of its nine outlets. If this combined current level exceeds 20 Amps at
any time, the circuit breaker will trip, cutting off power to the connected
equipment. If this occurs, the operator must reduce the load by unplug-
ging one or more units from the CN-2400S. Then push the button on the
circuit breaker (on the front panel) in order to reset it. Although 20 Amps
is an absolute limit, the CN-2400S will allow the operator to come as
close as possible to using the full 20 Amps. Power sequencing greatly
reduces the risk of tripping the breaker because the CN-2400S handles
large but temporary inrush currents in stages, rather than simultaneously,
allowing each stage to settle to its steady-state current draw before the
next stage is powered. If for any reason, reasonable efforts are made
to resolve breaker trips and trips continue, please to do not hesitate to
contact Furman technical support.

Re-syncing Multiple Sequencers
As discussed in previous sections, there can be unique situations where
multiple sequencers fall out of sync. This could occur because an electri-
cal circuit experiences an overload or high voltage. In the cases involving
Furman’s modernized SmartSequencing, an operator can press and hold
the Start Sequence pushbutton on the Primary Unit for several seconds
(or cycle the Primary to OFF on the Key Switch). When pressing and hold-
ing the pushbutton on dedicated SmartSequencing units, the Primary Unit
commands the Secondary Units to “Go Home” and all units will sequence
down in order. Once completely cycled off, the sequencers can be
sequenced on again by pressing the START SEQUENCE button or turning
the key switch to the ON position.
Re-syncing multiple sequencers in a Momentary Mode, whereby all units
are Primary, and wired in parallel across +12V, REM, and GND, re-
syncing can be accomplished by pressing and holding the Start Sequence
pushbutton. Unlike the SmartSequencing chains, units will cycle down,
yet may not cycle down in a hierarchical order. It would be advised that
all sound sources be muted before a re-sync action is initiated. Once the
re-sync is initiated, unit will cycle down and return to an off state.
A sequence can now be “ramped up” in order.
RS-232 disconnect
If a contractor unit loses communication to a controller or computer it is
advisable to set the unit’s Key Switch to OFF in order to re-establish com-
munication. Checking the physical connection would also be advisable if
communication is still not established.
BlueBOLT Communication
If the Ethernet LED does not illuminate, even though all attempts have
been made and the physical connection is known to be good, please also
ensure BlueBOLT indicator on the adapter is illuminated. If the adapter
LED is valid, please contact Furman Technical Support. Please note the
adapter is host to the IP Address and not the CN-2400S itself.
