The Function Keys
The ACK key is used to acknowledge alarms,
troubles, and supervisory conditions. In general
the LEDs change rom pulsing to steady to
indicate that the condition was acknowledged.
The SILENCE key silences the noti ication
appliance circuits that are con igured as
silenceable. Pressing the SILENCE key a
second time causes the NACs to re-sound.
The RESET key resets the SXL and all o the
smoke detectors.
The DRILL key activates all o the noti ication
appliance circuits.
The yellow zone status LEDs indicate
a trouble or supervisory condition existing on a
particular input. Pulsing indicates the condition
was not acknowledged; on steady indicates it
was acknowledged.
The red zone status LEDs provide an
indication o the status o a particular zone.
Pulsing indicates an alarm condition in that
zone. When the alarm is acknowledged, the LED
remains on steady until the panel is reset.
FRONT PANEL FUNCTIONS
The front panel of the SXL-EX is comprised of
a seven segment display, function keys, and
LEDs. Their functions are described below
(Refer to Figure 2):
The LEDs
The green Power LED remains on steady when
AC power is connected and pulses when the unit
is operating rom batteries.
The red Alar LED pulses when an alarm is
detected until it is acknowledged. Then it remains
on steady until the alarm condition is reset.
The yellow Supervisory LED pulses when a
supervisory condition is detected until it is ac-
knowledged. Then it remains on steady until the
supervisory condition is reset. Note that the
pulsing rates o the trouble and supervisory
conditions are di erent.
The yellow Trouble LED pulses when a trouble
condition is detected until it is acknowledged.
Then it remains on steady until the trouble condi-
tion is reset. Note that the pulsing rates o the
trouble and supervisory conditions are di erent.
The yellow Bypass/Alar Silence LED is on
steady when a zone in the system is bypassed
and it pulses when a noti ication circuit is silenced.
When an initiating device zone is bypassed, the
appropriate yellow zone trouble LED is on.
The Test/Progra LED is on steady when the
Test mode is selected and it pulses when the
Program mode is selected.
The Sounder

SXL-EX Operation, Installation, and Maintenance Manual
General Alarm is the default setting for all
zones. Alarm Verified Zone and Generic
Zone operation are described below.
 Shorting-type input devices and smoke
detectors are compatible with all zone
types.
 Manual fire alarm stations and smoke
detectors can be mixed on zones where
local codes allow.
 On verified zones, the manual station
reports alarms when activated, without
delay.
Alarm Verification
The Alarm Verification Feature provides the
SXL-EX with a way to verify an alarm from
area-type smoke detectors. This feature can
be used to reduce incidences of false alarms.
A detector supervised with Alarm Verification
is turned off by the System immediately after
it reaches an alarm threshold. The trouble
LED for that detector's zone turns on. The
detector is verified for a length of time which
must not exceed 60 seconds. After power is
restored to the device, and for the next 60
seconds, if the detector once again reaches
the alarm threshold the system will report an
alarm condition. If after 60 seconds the
detector has not alarmed, any detector which
again reaches the alarm threshold will restart
the verification cycle. See Figure 7, page 12,
for a graphic illustration of the Alarm Verifica-
tion Time cycle.
CAUTION:
Use only detectors which are subjected to
air velocities of less than 100 feet per
minute with Alarm Verification. Under dy-
namic air velocity conditions, smoke may
be swept from a smoke detector after the
initial alarm. That may cause a long delay
before verification. Do not select Alarm
Verification for such applications
display. If an alarm occurs after the trouble is
annunciated, the 7-segment display will clear.
To A knowledge Troubles
1. Unlock and open the door.
2. Press ACK to acknowledge (Block
Acknowledge) all troubles and other
conditions. The system TROUBLE LED
and the Zone TROUBLE LEDs on the
front panel stop flashing and remain on.
The systems internal audible silences.
To Reset
Press RESET. (The system will not reset until
all alarms, supervisories, and troubles are
acknowledged and all conditions are returned
to normal.)
System Feat res
In addition to the standard modes of opera-
tion for reporting system conditions, the
SXL-EX has user-programmable features
that are described below. Each topic identi-
fies the Program Level used to select these
features. Refer to the Programming section
of this manual for instructions on how to
activate these features in your SXL-EX
System.
Initiating Device Circ it (Zone) Types
(Program Level 3)
The SXL-EX has the following zone types.
 General Alarm
 Alarm Verified Zones
 Supervisory Zones
 Generic Zones

12
SXL-EX Operation, Installation, and Maintenance Manual
Figure 7
Line Graph of Alarm Verification
Alarm Verification in the SXL-EX is applied
globally to all selected zones. Therefore,
when a detector reaches its alarm threshold
and begins the Alarm Verification Time cycle,
any detector on any alarm verified zone will
react to smoke conditions as if its own Alarm
Verification Cycle had begun with the first
detector.
Generic Zone
The generic zone is activated (or alarmed) by
the output from another control panel. This
output should be made with a contact device
connected across the Generic zone. When
activated, it causes the notification appliance
circuits to sound and the appropriate initiating
Zone LED to light. When the input is deacti-
vated, the NACs will silence. The System
alarm contacts do not change state.
Notification Appliance Circ it (NAC or
Bell Circ it) Type (Program Level 4)
The SXL-EX has two Notification Appliance
Circuits, each circuit is rated at 1.5 amps.
The Notification Appliance Circuits can each
be programmed for one of the following four
code choices:
1. Steady NAC
2. Temporal Code
3. March Time Code
. Simple Zone Code
A steady tone is the default choice for each
circuit. A nonsilenceable NAC has a steady
tone. Temporal Code is as defined by NFPA
72. (Simple Zone Code is explained below.)
Please note that while it is possible to pro-
gram the two NACs with different, non-steady
codes, it is not permitted by any authority.
Use only one nonsteady code in your SXL-
EX system.
When distributing power in the system,
remember that there are 3 amps available
between the two NACs and the auxiliary
output. Do not exceed 3 amps total current
draw from the system.
Simple Zone Code
Notification Appliance Circuits programmed
for simple zone code follow a pre-pro-
grammed code pattern. Devices are turned
on and off once for Zone 1 alarms, twice for
Zone 2 alarms, three times for Zone 3 alarms,
etc. The first alarms code is repeated for the
number of rounds programmed in the sys-
tem, then the next alarm is reported. The
minimum allowable number of rounds is
three.
When all zones in alarm complete their
specified number of rounds in turn, the entire
sequence begins again with the first zone in
alarm. This sequence is repeated until the
system is silenced or reset.
The system operator cannot silence the
appliances, or reset the system, until the
programmed number of rounds of code have
been completed for each alarm. After silenc-
ing the appliances, the system reports a new
alarm via its particular code, followed by a
resound of all previously silenced alarms.

any zone can be mapped to any number of
outputs. When the zone alarms, all mapped
outputs will turn on.
The outputs on the SZE- X and the SRC-8
are linked. The outputs are numbered 1
through 8. If a zone is mapped to an output,
for example output number 1, the first output
on the SZE- X and SRC-8 will turn on if both
modules are in use.
Bypass Zones and O tp ts (Program
Levels 1 and 2)
The SXL-EX can bypass both Initiating
Device Circuits and relays or open collector
outputs on the SZE- X Zone/Output Ex-
pander module and the SRC-8 Relay module.
 When a circuit is bypassed, the system
reports a trouble condition and the
Bypass LED will be on.
 When a zone is bypassed, the zone
trouble LED will also be on.
 When an output is bypassed, and both
the SZE- X and the SRC-8 are in use,
the respective output on both cards will
be bypassed.
Set System Timing (Program Level 6)
The SXL-EX has the following four timing
functions:
1. Verification Retard/Reset Timer
2. NAC Inhibit Timer
3. NAC Cutoff Timer
. Simplified Zone Code Rounds
The Alarm Verification Retard/Reset time
establishes the delay time required to provide
an alarm verification cycle as determined by
the system owner or the local authority.
(Complete instructions for the proper selec-
tion of this timer follow.)
The NAC Inhibit and Cutoff Timers provide
automatic control of evacuation signals.
 The inhibit timer prevents any user from
silencing the notification appliances
before the selected time expires.
 The cutoff timer automatically turns off all
notification appliances after the selected
time expires.
Each timer has eight separate selections.
When the cutoff timer is set at No Cutoff (0
minutes), there is no automatic cutoff and the
appliances are energized until silenced or
reset.
The last timing function sets the number of
rounds of code for those systems using
Simple Zone Coding. (Please see the above
discussion of NAC types for a full explanation
of Simple Zone Coding.) The minimum
number of rounds is 3 and the maximum
programmable number of rounds is 8.
Alarm Verification Retard/Reset Timer
Selection (Program Level 6-1)
The selection of the Alarm Verification fea-
ture results in a delay of the system alarm
signal to the affected circuits. The total
allowable delay is 60 seconds. This delay,
the Alarm Verification time, is the sum of a
built-in 6 second system delay and the
programmed Retard/Reset time. The Retard/
Reset time can be set between 15 and 50
seconds, with 15 seconds being the pro-
grammed default. (See the definition of zone
types above for a further definition of the
Alarm Verification Time cycle.)

SXL-EX Operation, Installation, and Maintenance Manual
1. To select the proper Retard/Reset time,
begin with the Alarm Verification time
required by the system owner or local
authority.
2. Subtract the built-in 6 second system
delay. Make sure that the result is equal
to, or greater than the Detector Start-up
Delay from the Table below. If not, the
Alarm Verification Time must be length-
ened, or a new detector must be selected
for the installation.
3. Select the Retard/Reset time from the
programming instructions on page 18
which is closest to your result.
Example:
1. Alarm Verification Time required
by building owner = 30 seconds
2. Subtract the built in, 6 second
system delay 6 seconds
3. Result = 24 seconds
Select a Retard/Reset Time of 25 seconds from the
table on page 18 of the programming instructions.
NOTE: All detectors in the table below, except the
PE 3/3T and PE 11/11T, can be used for this
application. The PE 3/3T and PE 11/11T
Delay Startup is longer than the Retard/Reset
time and therefore would cause the Alarm
Verification time to exceed 30 seconds.

Set System Password (Program Level 7)
The System Password consists of four digits
using the four system keys: ACK, RESET,
DRILL, SILENCE. The password can be any
-digit sequence of these keys.
Set AC Fail Signal Delay (Program
Level 8)
Underwriters Laboratories, Inc. requires all
fire protection systems which communicate to
a Central Station or report as a Remote
Station to delay the transmission of AC Fail
Trouble Signals by a predetermined length of
time. The system default is a 6-hour delay
which is used for Central Station. For Remote
Station, use the 15 hour delay. The "no
delay" option is used for local fire alarm.
Enable System Option Cards (Program
Level 9)
The SXL-EX system has the capacity to
support the following option cards:
 Either the SRC-8 Relay module or the
SLT-1 Municipal Tie module
plus
 Either the SZE- X or the SZE-8AX Zone/
Output Expander module
plus
 1 or 2 Model LED-3/ Remote
Annunicators
The optional modules must be enabled in the
SXL-EX program or they will not function.
One Person System Test (Test Level 1)
This feature allows one person to test the
system by disabling it, activating initiating
devices, and listening for the building
audibles to sound. After the notification
appliances sound, the system will reset and
wait for the next device to be activated.
The system can also be tested without the
notification appliances. A second person
must watch the system display for indication
of activated zones. If the system is left inac-
tive during the test, the system will reset to its
normal operating mode after 20 minutes.
NOTE: Supervisory zones will appear as alarm
zones during this test and the zone
alarm LED will turn on.

Last Event Record (Test Level 4)
This feature records the zone in which the
last event occurred in each of four catego-
ries: Alarms, Troubles, Verified Alarms, and
Supervisories. This can be used for trouble-
shooting one-time reports of events.
Program Mode
The program mode allows the user to change
the configuration of the SXL-EX system. The
program mode has nine levels. Each level
allows the user to configure a different func-
tion within the SXL-EX.
When the program mode is enabled, the
current programming levels and sublevels
display in turn on the seven segment display.
The order of the display is as follows:
1. the program level is displayed first
2. then a hyphen (-) is displayed
3. then the sublevel is displayed
. then the display is blank.
The entire sequence then repeats.
In the programming mode, the four function
keys operate differently than they do in the
normal mode. Their functions are as follows:
The Acknowledge key toggles between the
Test mode, the Program mode, and the
Leave mode. The seven segment display
shows t, P, and L, respectively, to indicate
these modes.
The Reset key is used to select program
levels and options inside the programming
levels.
The Drill key selects options and toggles
options on and off.
The Silence key selects different sublevels.
Pressing silence when the seven segment
display shows L exits the user from the
