The MAESTRO-1600 is a programmable modular alarm control
system, designed to be easily customized as required by the end
user. The simplest version consists of an 8-zone control module
that operates in conjunction with one or several stylish
keypad/display units. Two types of LED keypads and two types of
LCD keypads are available.
By addition of a two-way communicator - the DL-1000 - the
MAESTRO-1600 becomes MAESTRO-1600DL. The communi-
cator reports events to central stations or private telephones, and
also permits data download / upload from a remote terminal.
Power pack kits adapted to the requirements in the country of use
are supplied as requested. A power pack kit consists of a power
transformer and an AC input terminal block with a built-in fuse.
Optional modules such as a zone expander and a siren driver are
also available for system enhancement.

• The control module: This module accommodates all control
circuitry and operation software for a programmable 8-zone
alarm system.
• DL-1000: A two-way digital communicator. It reports events to
two central stations or to four private telephones (or to a pager).
In addition, it accepts programming data and control commands
from remote download/upload terminals. This module plugs into
a socket at the left-hand edge of the system control module.
• Keypad / display units (ordered separately): These units
enable the installer and the user to enter their commands and
provide visual and audible feedback for every action. Four types
are available, as described in Sec. 4.
• PK-1 power pack kit (ordered separately): Step-down
transformer with 16 VAC output and fused AC input terminal
block. The kit is adapted to the AC mains voltage in the country
of use and to the regulatory requirements in that country.
• 12V backup battery (ordered separately): Provides operating
power in case of an AC failure.

An alarm system based on the MAESTRO-1600DL must include,
as a minimum, the units which are shaded in Fig. 1.2. Each
optional unit (shown in dotted lines) contributes additional
capabilities to the alarm system.
Various detectors must be wired to the control module's zone
inputs, same as in any other alarm control panel. The detectors
are not shown in the diagram, but their existence is suggested by
the zone loop circuits.
A.All servicing should be undertaken by qualified services
personnel.
B.Electrical wiring must comply with the local standards and
regulations that are valid at the time of installation.
C.Do not perform service or repair operations unless the mains

As the nerve center or the brain of the entire alarm system, this
programmable module includes the hardware and firmware
necessary for managing the system with or without auxiliary
modules - the communicator, zone expander and the siren driver.
It must be stressed, though, that at least one keypad/display unit is
required to set up a workable 8-zone alarm system.
Figure 3.1 The MAESTRO-1600 Control Module
The control module (Fig. 3.1) comes mounted within the alarm
control cabinet. Its printed circuit board is equipped with a socket
for the communicator module (at the left hand edge) and a socket
for the siren driver module (at the right hand edge).
Operating power is supplied from a 16 VAC / 40 VA stepdown
transformer - part of the power pack kit PK-1. The control module
accommodates a voltage regulator and a charger for the backup
battery. Regulated 12 VDC output for the detectors, all the
keypads and other external devices is obtained via an on-board 1A
fuse marked "ACCESSORIES". Two pairs of 12VDC output
terminals are provided, to allow easier connection of a large
number of accessories.
The ALARM relay has changeover (Form 1C) dry contacts rated at
5A/24 Volts, and can be used to activate alarm devices such as
sirens or bells (Fig. 3.7). A jumper marked V-BELL connects the
12 VDC supply to the common (C) contact of the alarm relay, via a
3A fuse marked BELL. With the jumper installed across the two
V-BELL pins, the bell or siren can be wired between the N.O.
contact of the relay and the negative (–) supply terminal.

The AC power pack for the MAESTRO-1600 is delivered
separately in kit form, to suit the mains voltage and the particular
regulations in the country of use. The kit includes a step-down
transformer, an AC mains terminal block with a built-in fuse holder
and a 0.3 A fuse, mounting hardware and a terminal identification
sticker. As an essential part of the alarm control system, the power
pack must be installed in the metal cabinet (Fig 3.2) and wired
accordingly (Fig. 3.3).
A. Align the transformer mounting ears with the 2 stand-off screws
on the rear wall of the case and let the screws pass through the
holes. Mount a flat washer, a lock washer and a nut (in this
order) on each screw and tighten both nuts.
B. Place AC mains terminal block with its ground lug over the
stand-off grounding screw, and the hole nearest to the fuse
holder over press nut. Pass a screw (supplied in the kit)
through that hole and thread it into press nut. Tighten screw
well. Put a lock washer and a nut over the stand-off grounding
screw and tighten nut to fasten ground lug to the case.
C. Remove the paper backing from the terminal identification
sticker and attach the sticker to the rear wall of the case, as
close as possible to the AC terminal block.

D. The primary winding of the transformer is already connected to
the terminal block, as shown in Fig. 3.3. Connect the
transformer's 16 VAC winding (the 2 free wires) across the
control module's 16 VAC terminals.
E. Connect AC mains input – Phase (~), Neutral (0) and Ground
() to terminal block (see Fig. 3.3). Make sure your
installation complies with the following safety requirements list:
• Conductors carrying the AC mains voltage should be
physically separated from other conductors used to wire
the alarm system.
• The cross section of the mains input conductors must be
not less than 1.0 mm2(17 AWG).
• The diameter of the plastic conduit for the mains cable
should be at least 16 mm (5/8 in.)
• Insert the plastic conduit as far as 3 cm (1-1/8 in.) into the
metal case, to protect the mains conductors from the sharp
edges of the entry hole.
• All 3 AC power supply leads must be tied together firmly
with a plastic tie wrap close as close as possible to the
terminal block to which these leads are connected.
• The phase (~) input wire must be routed via a single-pole, 3A
exclusively dedicated circuit breaker.

Two optional kits are offered for enhancing the alarm control system:
LK-1: key-operated lock for the front lid of the metal cabinet (see A
below)
TK-1: tamper switch kit (see B below)
A. Assembling the Front Lid Lock Kit (LK-1)
The LK-1 lock kit includes the lock itself and mounting hardware as
shown in Fig. 3.4. To assemble the lock, proceed as follows:
(1) Align the lock with the pre-punched hole in the lid, insert it into
the hole and use the nut to fasten it to the front lid. Tighten the
nut with a spanner wrench.
(2) Mount the rotation limiter over the rotating part of the lock,
making sure that the small cam on the lock body is positioned
between the two teeth that limit the rotation angle.
(3) Mount the lock bar over the rotation limiter.
(4) Use spacer and the screw to tighten the entire lock assembly.
(5) Insert the key into the lock and check whether the rotation
limiter allows the lock to be rotated in the desired direction.
B. Assembling the Tamper Switch Kit (TK-1)
The TK-1 kit includes the tamper switch with two wires soldered to
its terminals and two sheet metal screws. To mount the switch on
the tamper bracket, proceed as follows:
(1) Align the tamper switch with the bracket as shown in Fig. 3.5.

DE5110 7
(2) Use the two sheet metal
screws to fasten the
switch. to bracket. Tighten
the screws well, but do not
overtighten because this
may break the switch.
(3) Verify that the switch
contacts close when the
front lid is closed.
(4) Connect the tamper switch
wires to the zone terminals
of a zone dedicated to
24-hour tamper protection.

BUS These are the keypad bus terminals for the various
keypads and for the expander module. Each terminal
should be wired to its identically numbered counterpart
in the keypad/display unit or expander module. Refer to
Sec. 8 - Keypad Bus Length Considerations.
Z1 Zone 1 terminal. A normally closed (N.C.) zone loop
will be formed if the alarm contacts of all detectors in
this zone are connected in series between this
terminal and the nearest (–) terminal. A 10 kΩ
End-of-Line (EOL) resistor must complete the series
connected loop at the point most distant from the
zone terminals.
Note: If a zone is defined as a keyswitch zone and
used for arming/disarming, a 10kΩresistor must be
wired across the keyswitch terminals
.
(–) A negative common terminal. Each zone loop is
connected between the respective zone terminal and
a (–) terminal.
Z2 The wiring instructions are the same as for zone 1,
with which zone 2 shares the (–) terminal.
Z3 - Z8 Three pairs of zones, with a (–) terminal between
each pair. Wiring instructions are the same as for the
first pair of zones (Z1 and Z2).

Terminals Wiring Information
PGM 1 This is a programmable open-collector auxiliary
output (100 mA max.). You may program this output
to pull to ground upon communication failure.
Alternatively, you may program it to pull to ground for
as long as the system is armed (for controlling the
alarm memory function in certain detectors), or for
lighting an remotely located LED to indicate that the
system is armed.
An LED with 1kΩresistor in series may be wired
between PGM1 and any one of the 12 V+ terminals,
as shown in Fig. 3.6. A relay can also be wired as
shown with PGM2.
PGM 2 This is a programmable open-collector auxiliary
output (100 mA max.). You may program this output
to pull to ground during exit and entry delays, or to
pull to ground whenever the system is ready - all
zones are secured and ready to be armed. In the first
case, a courtesy light control relay or a warning
buzzer may be wired between PGM2 and any one of
the 12 V+ terminals (Fig. 3.6). In the second case, a
READY LED with a 1kΩresistor in series may be
wired between PGM2 and any one of the 12 V+
terminals.
PGM 3 This is a programmable open-collector auxiliary
output (100 mA max.). You may program this output
to reset smoke detectors after the first detection of
smoke, or to pull to ground upon any alarm and return
to the open circuit state only by disarming or arming
the alarm system (strobe output). In the first case,
PGM3 must be wired as the "ground return" for the
smoke detectors used in the system, as shown in
Figure 3-6. In the second case, a strobe light control
relay may be wired between PGM3 and any one of
the 12 V+ terminals.
ALM This is an open-collector output that pulls to ground
during alarm and returns to the open circuit state
when the alarm times out. It may be used to activate
an auxiliary alarm device.
ALARM The N.O., C and N. C. terminals represent the
corresponding output relay contacts. You may wire
the alarm relay contacts to switch on an external
siren by supplying +12 VDC to the siren as shown in
Fig. 3.7.
Note: If the V-BELL jumper is installed across the
two V-BELL pins, +12VDC is applied to the output
relay C contact. The N.C. contact will also be at
+12VDC potential, but will become "floating" when
an alarm occurs. If you wish to use the output
relay as a "floating" dry contact switch, be sure
to remove the V-BELL jumper!
12 VDC Two pairs of 12 VDC supply terminals. Up to 700 mA
maximum current can be obtained across the [+] and
[–] terminals, but this includes the current. drawn by
the keypads, the zone expander and the various
detectors.
16 VAC AC power input terminals. The system is powered by
16 VAC output from a 40 VA power transformer,
which changes according to the country of use. The
secondary winding of the transformer (the two free
wires extending from the transformer) must be
connected across these terminals.

When installing a new
MAESTRO-1600, you should
always replace the factory
default installer code with a
secret code, known only to
yourself (see Installer's Prog-
ramming Guide, Location 01). In
the User's Guide, the master
Figure 3.7 Connecting a Siren
user is similarly instructed to program a secret master code,
known only to himself.
It is highly unlikely that the user should forget his code, but if he
does - you can help him by performing a "software reset" (see
Location 41 in the Installer's Programming Guide). This reset can
not be carried out without your installer code.
It is also quite unlikely that you lose your installer code, thereby
losing your ability to access the system for reprogramming.
However, if you do lose the code, don't lose hope: you can still
perform a "hardware reset", which will restore the system to the
factory default installer and master codes.
The hardware reset procedure is as follows:
• Use a jumper bar to short together the two CLEAR pins on the
control module (Fig. 3.6 for location of the pins).
• Disconnect all power - the AC mains as well as the battery.
• Reconnect the battery, wait 5 seconds, remove the short circuit
from the CLEAR pins and disconnect the battery once more.
• Reconnect the battery and the AC mains. The system will revert
the default Installer code (160 0) and Master User code (1234 ).
When done, use the factory default installer code to access the
installer mode and program a new secret installer code (see
Location 01 in the Installer Programming Guide). Also inform
the master user that he must reprogram his secret Master Code.

The DL-1000 communicator module is supplied as part of the
MAESTRO-1600DL.
A board-to-board connector on the DL-1000 left edge (Fig. 4.1)
mates with a socket at upper left edge of the alarm control module.
The communicator is triggered into action by the alarm control
module, and can be programmed to communicate with central
stations or private telephones, as required. The communication
protocol is selected in the course of programming (refer to the
programming manual).
The communicator is designed and programmed to play two roles:
• Event Reporting: Once an event occurs, the communicator
calls the telephone numbers programmed by the installer or by
the user. When communication is established, the
communicator reports the event (or events) by sending DTMF
or pulse code sequences (if the central station mode has been
selected) or two kinds of alarm tone signals (if private telephone
mode has been selected). Acknowledgement is expected from
the called party for each event reported, or else communicator
will report the event repeatedly until factory-programmed
number of message repetitions is exceeded.
• Interaction with a Remote Computer: The DL-1000 and the
control module combine together to handle Download/Upload
requests from a remote computer. These operations require a
remote modem - the RM-1000 - at the remote computer's end of
the line and the RPM-1 software package (see Appendix A).
The remote modem and the software also allow full control of
the alarm system by the remote computer (arming, disarming,
bypassing zones, displaying zone status etc.). To assume
control, the remote station operator establishes telephone
communication with the protected premises (see Chapter 6 in
the programming manual). DTMF code sequences are then sent
by the remote station over the telephone line. The DL-1000
interprets these DTMF codes and transfers commands, new
parameters and data-upload requests to the control module.
The control module will carry out the commands, or reprogram
itself or allow upload, as the case may be.
 2SHUDWLRQ 5RXWLQH
A. Reporting to Central Stations
Once triggered into operation by the occurrence of an event, the
communicator carries out the following sequence of operations:
(1) It seizes the line and waits 10 seconds for dialing tone.
(2) Upon detection of a 2-second long dialing tone, the
communicator starts calling the first-priority telephone number
of the first central station.
Note: Without dial tone, the communicator goes "on hook" for
about 5 seconds, then seizes the line again to wait for dial tone.
If there is still no tone, dialing starts anyway, except in cases
where a hexadecimal "D" is programmed as a prefix to the
telephone number. With a D-prefix, dialing will not take place
unless a dial tone is detected (see the Programming Manual for
additional information).
(3) Once the call is answered, the communicator waits 16 seconds
for a GO-AHEAD signal from the central station. To prolong
this standby period, a hexadecimal E programmed at the end of
the telephone number will introduce an additional 10 second
delay. If there is no GO AHEAD, the communicator will go on
hook and redial the second priority phone number for that
central station.
Note: If there is no second phone number, the first number will
be called again until the preprogrammed maximum number of
dialing attempts is reached.
(4) If a GO-AHEAD signal is received within 16 seconds, the
communicator reports the first event in its transmission queue

DE5110 11
and waits 4 seconds for a
KISSOFF signal. Upon
KISSOFF, the communi-
cator checks whether
another event is waiting
to be reported (alarms
are always reported be-
fore restorals).
(5) If there is a second event
to be reported, the com-
municator reports it and
disengages the line upon
reception of KISSOFF for
the second event. The
communication session is
considered successful.
Figure 4.1 The DL-1000
Communicator
Note: Without KISSOFF from the central station, messages will
be repeated until the factory default number of "message
repetitions" is reached. Next, the second (backup) telephone
number will be called and a communication session will be
attempted. If this fails too, the COMMUNICATION FAILURE
code will be sent to the control module, which will produce the
relevant TROUBLE indications.
(6) Upon completion of a successful or ineffective communication
session with the first central station, and provided that the
communicator has been programmed to call the second central
station, the entire procedure will be repeated, but this time with
the telephone numbers of the second central station.
B. Reporting to Private Telephones
Unlike central stations, private telephones are not equipped to
interpret event codes. When programmed to report to a private
telephone, the communicator transmits only two types of alarm
tone signals over the telephone line:
• A two-tone siren to indicate an alarm in a regular zone.
• A swept-tone siren to indicate an alarm in a 24-hour zone.
In Private Telephone mode, the first telephone number becomes a
"follow me" number, which is programmed by the master user
each time before arming the alarm system and which will be
deleted automatically upon disarming. The other 3 numbers are
programmed by the installer as permanent reporting destinations.
Once triggered into operation by the occurrence of an event, the
communicator carries out the following sequence of operations:
(1) It seizes the line and waits 10 seconds for dialing tone.
(2) Upon detection of a 2-second long dialing tone, the commu-
nicator starts calling the "follow me" number. If no such number
is programmed, the first of the other 3 numbers will be dialed.
Note: If there is no dial tone, the communicator goes "on hook"
for about 5 seconds, then seizes the line again and waits once
more for dial tone. If there is still no tone, dialing starts anyway,
except in cases where a hexadecimal "D" is programmed as a
prefix to the telephone number. With a D-prefix, dialing will not
take place unless a dial tone is detected.
(3) Once called party answers, communicator waits 5 seconds and
transmits relevant signal (two-tone or swept siren, depending
on the type of alarm event). The siren sounds for 15 seconds
and stops for 5 seconds, throughout which communicator
stands by for an acknowledgement (DTMF "0" or "2").
DTMF "0" will cause the communicator to consider the
communication session successful and cease any activity.
DTMF "2" will cause the communicator to consider the event
closed for the presently contacted telephone only, but to
continue calling the remaining telephone numbers.
Note: Without an acknowledgement, the siren will sound the
maximum number of times allowed by factory programming (5
times). The communicator will then disengage the line and call
the other telephone numbers by order of priority. Each
telephone will be called the maximum number of times allowed
by factory programming, unless proper acknowledgement is
received by the communicator.
(4) If a 24-hour zone alarm occurs while a regular alarm is being
reported, the communicator will automatically switch to the
swept-tone alarm.

12 DE5110
Note: If all communication attempts fail, a "communication
failure" code will be sent to the control module, which will
produce the relevant TROUBLE indications.
C. Download/Upload/Remote Control Capabilities
Besides its task to report alarms via the public telephone network,
the DL-1000 communicator permits the following functions:
• Arming the MAESTRO-1600DL and programming telephone
numbers from a remote DTMF telephone (refer to Sec. 6 in the
Installer Programming Guide).
• A full extent of system control and data download/upload with a
remote computer terminal via telephone lines (Appendix A).
• Data download/upload with a local computer terminal via the
local download/upload header of the alarm control module
(Appendix A).
 0RXQWLQJ
Any MAESTRO-1600 may be converted into a MAESTRO-1600DL
by addition of the DL-1000 module, which can be ordered separately.
Refer to Fig. 1.1 for module location. Mate the board-to-board
connector on the DL-1000 with the socket at the upper left edge of
the alarm control module. Once the connectors are mated, the two
left-side mounting holes of the DL-1000 will be aligned with two
stand-offs in the rear wall of the metal cabinet. Use two screws to
fasten the DL-1000 to these standoffs.

anywhere within the protected premises. Each keypad/display unit
is connected to the control panel via the four lead keypad bus -
two data wires and two power supply wires. Four types are
currently available:
• KP-1001/8 - Keypad with LED display for an 8-zone system
• KP-1001/16 - Keypad with LED display for a 16-zone system
• KP-1002 - Keypad with regular Liquid Crystal Display (LCD)

• A 3 x 4 key numerical keyboard
• A column of 4 function keys: AWAY, HOME, INSTANT and
BYPASS.
• A row of 3 special "quick-action keys": A, B and C.
In the KP-1001/16, sixteen LED indicators represent the 16 zones,
respectively. In the KP-1001/8, indicators 9 through 16 do not
exist, and 8 LED indicators represent the 8 zones, respectively.
The group of 6 LEDs at the right hand side of the panel consists of
status indicators marked: READY, ARM, POWER, BYPASS,
MEMORY and TROUBLE.
The front panel keys and indicators serve as an interface between
the alarm system and the installer or the user. The indicators provide
status information, display memorized data and also inform the
installer or the user about the success or failure of each operation.

The following list includes interpretations for the basic states of the
six front panel function indicators. Two basic states - a lighted
indicator and an extinguished one - are explained below.
Other indications are dealt with in the programming guide and the
user's guide.
• READY indicator: This indicator lights steadily if all zones are
secured and the MAESTRO-1600 is ready to be armed. An
extinguished READY indicator warns you of "open" zones (but
not when type 1 delay and follower zones are open).
• ARM indicator: This indicator lights steadily throughout the
armed period. An extinguished ARM indicator informs you that
the system is in the disarmed state.
• POWER indicator: This indicator lights steadily while AC power
is supplied to the system. An extinguished POWER indicator
denotes a power failure.
• BYPASS indicator: This indicator lights steadily to indicate that at
least one zone has been selected for bypassing. An extinguished
BYPASS indicator means that none of the zones is bypassed.
Note: The BYPASS indicator functions only while the system is
disarmed; bypassing is not possible while the system is in
the
armed state.
• MEMORY indicator: This indicator lights steadily while the
system is in the disarmed state as a sign that an alarm occurred
throughout the last arm period or throughout the ongoing
Disarm period. An extinguished MEMORY indicator is a sign
that the recent arm/disarm cycle has been uneventful.
Note: The alarm memory is cleared upon arming, and the
MEMORY indicator does not function while the system is in the
armed state.
• TROUBLE indicator: This indicator lights steadily whenever
trouble is detected. The trouble indication is cleared upon
arming. An extinguished TROUBLE indicator while the system is
in the disarmed state signifies a "no trouble" situation.

Keypad/Display units may be installed wherever required on the
premises, keeping in mind that the user must have easy access to
the keys and a free view of the indicators. Also keep in mind that
there is a limit to the distance between the keypad and the alarm
control cabinet (Sec. 8). To mount a keypad on the wall, proceed
as follows:
(1)
Shut the front lid of the keypad to protect the keys.
(2)
Insert a small screwdriver blade into one of the four slots near
the corners of the case (Fig. 5.3). Swing the handle up and
turn the screwdriver slightly to separate the two parts of the
case at that corner. Then similarly separate the other corner on
the same side of the case. Raise the free side of the base
diagonally and pull the base out.

the same terminal block at the same location on the printed circuit
board. For this reason, only the KP-1001 printed circuit board is
shown (Fig. 5.5). The terminals are numbered from 1 to 4. If you
are using a color coded bus cable, note down the color of the wire
connected to each one of the control module's BUS terminals.
Going by colors, make a "one for one" connection, where terminal
1 in the control module is connected to terminal 1 in the keypad,
terminal 2 to terminal 2, etc.

IMPORTANT! If the keypad bus is cut off and not even a single
keypad is left connected to the alarm control module, a silent
alarm will be initiated, meaning that the communicator will send a
"keypad bus error" event code to the central station.
Keypad bus error will be reported provided that you program the
required event code in Location 34 - refer to the Installer's

The zone expander is a micro-processor controlled module
designed to increase the system zone capacity from 8 to 16. It can
be mounted either within the metal cabinet that hosts the alarm
control module, or separately elsewhere within the protected area.
If located within the metal cabinet, the EXP-1600 is connected to
the control module via a short flat cable terminated with 4-pin
plugs (this cable is supplied with each expander). Special 4-pin
sockets are provided for this purpose on both the expander board
(Fig. 6.1) and the control module board.
Installation away from the system control housing reduces the
distance between the expander and its associated zone detectors.

16 DE5110
A remotely located zone expander is connected to the control
module via the same 4-wire bus that serves the control keypads.
The bus, that utilizes multiplex communication techniques, is being
constantly supervised by the control module, and a trouble alert is
generated if a malfunction occurs. The EXP-1600 accommodates
terminals for the additional 8 zones, and 12 VDC output terminals
for supplying power to detectors used in the additional 8 zones.
The 12VDC output terminals are especially useful in installations
where the detectors of the additional 8 zones are closer to the
expander than to the alarm control module. An optional plastic
housing - the UPB-3 - can be used for remote installation of the
EXP-1600 (Para. 6.2 B).
 0RXQWLQJ
Any MAESTRO-1600 or MAESTRO-1600DL may be expanded to
control 16-zones by addition of the optional EXP-1600 module.
This module can be mounted within the control cabinet or at a
remote location, as described in the following paragraphs.
A. Mounting within the Alarm Control Cabinet
If you prefer to install the EXP-1600 within the metal cabinet, refer
to Fig. 1.1 for correct
location of this module.
Align the 4 mounting
holes of the expander
module with the 4 stand-
offs on the rear wall of
the metal cabinet. Use
four screws to fasten the
EXP-1600 to these 4
standoffs. Next, connect
the short flat cable
assembly supplied with
the EXP-1600 between
Figure 6.1 Zone Expander EXP-1600
the 4-pin sockets on the EXP-1600 and the alarm control module.
Align the plugs properly before insertion!
B. Distant Mounting (Fig. 6.2 & 6.3)
To mount the EXP-1600 in an optional UPB-3 housing:
(1) Remove the screw that secures the UPB-3 cover to the base.
(2) Insert a small screwdriver blade into the slot near one of the
snap-in teeth, as shown. Carefully flex the cover edge out, until
the tooth disengages the dent. Repeat this with the other tooth
to free the cover edge completely.
(3) Lift the free edge of the cover diagonally up and get the other
edge free by pulling it backwards to disengage tabs at back.
(4)
Hold the base against the mounting surface and mark the
points for drilling.
(5)
Drill the mounting holes and insert wall anchors if necessary.
Insert the wires into the base via any of the wiring holes.
Attach the base to the mounting surface with two screws.
(6)
Put the expander
module in place (see
Fig. 6.3) with the bottom
edge seated in the
module edge support.
Align the holes at the top
of the PCB with the
plastic standoffs in the
base. Secure the mo-
dule to the base with
short hold-down screws

12 VDC A pair of 12 VDC (+) and (–) supply terminals. The
maximum current that can be obtained for external
devices depends on the amount of current already
drawn from the main control module by external
devices. The total current should not exceed 700
mA.
BUS Terminals 1 through 4 serve for connecting the
expander to the system via a 4-wire keypad bus.
Each terminal should be wired to its identically
numbered counterpart in the MAESTRO-1600
control module or in one of the keypads. Refer to
Sec. 8 - Bus Length Considerations.
Z9 Zone 9 terminal. A normally closed (N.C.) zone
loop will be formed if the alarm contacts of all
detectors in this zone are connected in series
between this terminal and the nearest (–) terminal.
An 10 kΩEnd-of-Line (EOL) resistor must
complete the series connected loop at the point
most distant from the zone terminals.
(–) A negative common terminal. Each zone loop is
connected between the respective zone terminal
and a (–) terminal.
Z10 The wiring instructions are the same as for zone 9,
with which zone 10 shares the (–) terminal.
Z11 to Z16 Three pairs of zones, with a (–) terminal between
each pair. Wiring instructions are the same as for
the first pair of zones (Z9 and Z10).
Note: The module is shown here as viewed when installed within

When installing the MAESTRO-1600, you must take into account
that the copper wires used to set up the keypad bus have specific
resistance per unit of length, depending on the diameter of the
wire. There is always a distance beyond which keypads (or the
zone expander) will not work properly, due to the voltage drop
along the cable. Keypads are usually "chained" along the bus, and
an example of such "chaining" is shown in Fig. 8.1. In the
configuration shown above, the voltage drop along the bus
depends on the currents drawn by the various units and on the
resistance of the bus wires. Your purpose should be to plan ahead
so that the voltage at the far end of the line will not drop below the
10 V threshold with proper AC supply to the system.
Planning in advance will enable you to obtain a cable of appropriate
gauge for the particular application. You will thus prevent low voltage
problems that may compel you to re-wire the bus.

∗ If you use the calculating method given in Para. 8.3 below, this
number will help you determine whether the wire you intend to
use will not cause an excessive voltage drop.
The current drawn by the various keypads and zone expander are:

Suppose you intend to use AWG 24 wires in the case presented in
Fig. 8.1, and you wish to verify that this wire gauge will do.
A. Multiply the distance of each unit on the bus by the current
drain (in mA) of that unit, as done in the following table (you
may use meters or feet, as desired). When done, sum up all
products of all multiplication made. The results are shown as
"total" for both meters and feet.

B. At this stage, all you have to do is compare the computed total
with the reference number pertaining to AWG24 in the wire
data table (Para. 8.2). The reference numbers are 21,000 (for
meters) and 68,900 (for feet).
• If the number you computed is smaller than or equal to the
reference number, then AWG24 wires are suitable for this
application.
• If the number you computed is larger than the reference
number, then you should consider using a smaller AWG
number (larger diameter cable).
NOTES:
1. If various detectors draw current from the distant expander, the
calculation in A above must include them as well, in
accordance with their individual distances from the alarm
control module and their individual current consumption.
2. Once the installation work is done, it is recommended to
measure the voltage at the end of the line, to verify that the last
unit does not receive less than 10 volts DC (while the AC
supply is normal).
3. If several keypad buses are branched out in parallel or in
different directions from the alarm control module, each bus
must be treated separately.
