The ESL 1500 Series Control Panels are designed to provide reliable and economical fire alarm control solutions for commercial,
industrial, residential, and institutional applications. The 1500 Series consists of three base models, equipped with one (Model
1501), three (1503), or five (1505) zones. The unique modular design makes it easy and practical to add features such as extra
relays, remote annunciators or added fire zones (up to 5).
All models come equipped with a Basic Master Board (BMB), which provides all common system functions for alarm, fault, and
supervisory monitoring, together with one initiating and two indicating circuits. Models 1503 and 1505 also include Zone
Expander Modules (ZEM), expanding the systems capability from three zones up to a maximum of five zones.
One housing is common to all three system configurations. The cabinet holds all standard and optional modules as well as
necessary standby batteries for either 24 or 60 hour protection.
Combine the versatile 1500 Series with the complete line of compatible ESL smoke detectors, pull stations, and indicating devices
for a reliable fire control system. See Appendix A for a list of UL Listed compatible devices.

Installing the Panel
To install the unit, follow these 12 steps, and refer to the proper sections for more information.
1.Create System Diagram: Prepare a carefully laid out drawing of the complete wiring system hookup. Maintain this
drawing as a permanent record of the system application and include any future modifications.
Note: “As-built” drawings and this manual should be available at all times to verify agreement between the
connected equipment and the drawings.
2.Inspect Equipment: Carefully unpack the system components and inspect for shipping damage. Report any shipping
damage to place of purchase.
3.Mount Cabinet: Mount the cabinet in a clean, dry, vibration-free area, where the temperature range does not exceed 0°
to 49° C (32° to 120° F). Mount only in interior locations. Allow adequate space for 180 degree door swing and free
access to sides for conduit entry. Locate the top of the cabinet approximately 6 feet (1.8m) above the floor, with the hinge
mounting on the left. Mounting holes in the back of the cabinet are designed so the cabinet can be mounted without removing
any control equipment. Mount the cabinet to the wall by first installing the top center mounting screw, leaving enough space
so the cabinet can be hooked over the screw head. Use screws or bolts no smaller than #10 or 3/16 inches in diameter. For
easier access, remove the door by gently lifting it from the hinges.
4.Connect Conduit: Complete all connections to the cabinet with conduit fittings or bushings. Use the knockouts provided in
the sides of the cabinet.
5.Pull Wire: Pull all system wiring through installed conduit following the guidelines of Article 760 of the National Electrical
Code (NFP A 70) and/or local codes for fire alarm systems. Observe power limiting codes when running wire.
See Installation Recommendations/Precautions for more information.
6.Program Components: Before wiring, examine installation of all modules, chassis and sub-assemblies to ensure proper
mechanical and electrical connections and programming switches have been selected. See Programming for options.
7.Connect AC: Connect line voltage to transformer leads located under the BMB. Transformer wires are long enough
so you do not need to remove the circuit board.
8.Connect Batteries: Determine the total system power requirements by using the Standby Battery Power Worksheet
in Appendix B.
9.System Check: Make certain the 1500 panel is operating properly before connecting field wiring by performing a
system check. ESL makes this easy by factory installing end-of-line resistors to the proper Class B zone terminals. To test
the panel, make sure all switches are in their normal position and power the system by connecting AC and then the
batteries. (Note: if new batteries with low terminal voltage are used, the Low/No Battery LED may activate. The Low
Battery indicator will deactivate after the batteries are fully
charged - no longer than 48 hours.) No fault indications
should be present. If faults are present, see Table 6. Trouble-shooting Guide. System check is now complete.
10. Check Field Wiring: Check the integrity of all field wiring
following directions defined in the Field Wiring CheckoutProcedures.This check must be performed before connecting
wiring to the system. Becertain all external wiring is correct
(no opens, shorts, or grounds) and is terminated with the
correct end-of-line devices.
11. Connect Field Wiring: Connect each circuit in turn,
following wiring diagrams provided. Do not make allconnections at once. This procedure will let you bring your
system on-line in stages and quickly identify which portion of
your system is not working.

System Reset
Resets control unit, provided the alarm condition has been cleared. Also interrupts power to the alarm initiating circuits of all
zones and to the auxiliary power output. The integral sounder will activate when the System Reset switch is activated.
Sounder Silence
Activating the switch during a trouble condition will silence the integral sounder. When all system faults are cleared, a “ring back”
feature will resound the integral sounder to indicate that the switch is in the silence position. Fault LEDs will remain active until
all faults have been corrected.
Zone Disconnect/Walktest
A three position switch provides for normal, test, and disable functions for each zone. Under standard conditions, no LEDs will
light when the switch is in the “normal” position.
Note: For maintenance use only! Notify your local fire department and receiving station before operating switch.
Zone Disconnect disables the alarm indicating devices so that service may be performed without sounding an alarm. When a
zone is disabled, zone and system trouble LEDs will light and the integral trouble sounder will activate. An alarm received from
any zone that has not been disabled will activate the indicating devices as normal. The zone disconnect switch is defeated when a
zone has been programmed for waterflow service. See BMB Programming.
Walktest makes it possible for one service person to functionally test initiating devices without having to constantly return to
reset the control panel. When activiated, the walktest feature sounds the indicating devices for approximately two seconds and
then resets the system. Only an alarm from the zone with the walktest activated will reset the system; all other zones will
function normally. To silence the indicating devices during the walktest mode, see BMB Programming.

Optional Remote Notification Disconnect
Applies to LEM optional module. Disconnects system
from remote sites. When activated, the trip circuit fault
LED and system fault condition will exist and remain until
the switch is returned to the normal position.
Note: Notify the local fire department and the
receiving station before disconnecting the LEM
from the system.

Alarm Condition
An alarm can be initiated by means of a smoke detector,
heat detector, manual alarm station, waterflow alarm
device, or other UL Listed initiating device. The red zone
alarm LED will light and the integral sounder will provide a
continuous, steady audible signal. Both alarm indicating circuits will activate and sound a general alarm. A set of dry, Form C
supplementary common alarm contacts will transfer and remain latched until the system RESET switch is operated. When used,
the supervised zone alarm output will energize. If provided, the remote communicator circuit will activate to summon organized
assistance.
Zone Alarm OffRedIndicates when an alarm
(by zone)condition is detected by
its zone.
Alarm Verification
When activated, alarm verification is very effective in reducing nuisance alarms. Nuisance alarms are reduced by requiring 2
separate alarm signals to activate the system When the first alarm is received from an initiating device, the verification feature
inhibits an alarm output for approximately 12 seconds. After this period, power is reapplied to the initiating circuits. If a second
alarm signal is received within 2 minutes, a system alarm is generated; if not, the system resets and no alarm is generated. Analarm from a manual station or heat detector, however, is never delayed more than 15 seconds. To activate alarm verification, see BMB Programming.
Note: When using alarm verification, total alarm delay (alarm verification + smoke detector power-up time) cannot exceed
60 seconds according to the National Fire Alarm Code (NFPA 72) or 30 seconds for installations governed by the California
State Fire Marshall. Alarm delay includes verification time (12 seconds) and smoke detector power-up time. Smoke detector
power-up time varies by manufacturer, however, the ESL 429, 449, 521, 541, 500N, and 700 Series detectors meet both
CSFM and NFPA requirements (ESL detector power-up time is 15 seconds).
During alarm verification, the Zone LED, Remote Annunciator and the Zone Relay Module (ZRM) may activate briefly
(approximately 12 seconds) during the initial alarm signal.
Zone Disconnect
Note: For maintenance use only! Notify local fire department and receiving station before operating the switch
if the control panel is monitored, as a “trouble” signal will be transmitted.
When activated prior to an alarm condition, this switch disconnects the local zone alarm from the auxiliary alarm relay and
alarm indicating circuits. When activated, the red local alarm zone LED turns on and, if used, the supervised remote annuncitator
LED lights. Only the disconnected zone is affected; alarm signals from other zones remain active.
When activated after an alarm condition, the auxiliary alarm relay remains latched and alarm indicating circuits are turned off.
The red local alarm zone LED remains on and, if used, the supervised remote annunciator remains on. Only the disconnected zone
is affected; alarm signals from other zones remain active. Additionally , if an initiating device is still in alarm when a zone disconnect switch is returned to normal, the alarm will again be transmitted to both the alarm indicating circuits and the integral sounder.

System Reset
System reset can only be accomplished when all actuated alarm devices have been restored to their normal, standby condition.
Note: Operating the system reset switch will return all alarm initiating circuits and system-powered inititating
devices to their normal standby condition. Mechanical initiating devices such as most fixed termperature heat
detectors and manual stations must be replaced or manually reset or the system will alarm again when the reset
switch is released.
T rouble Condition
Activation of the fault signal under normal operation indicates a condition that requires immediate correction. A fault signal
involves illumination of the system trouble LED (yellow) and individual diagnostic LED’s (yellow) generally associated with the
specific circuit affected. The integral sounder will sound a slow intermittent signal and a set of dry, Form C contacts will transfer.
Moving the SOUNDER SILENCE switch to the silence position will silence the audible trouble signal, but will not restore the
Form C contacts. Restoration to normal can only be achieved when all faults have been corrected and all switches have been
returned to normal position. Trouble reset occurs automatically when this is accomplished. If the SOUNDER SILENCE switch is
off-normal at the time all faults are clear, the “ringback” feature will alert the operator.
Supervisory Functions
Zone 2 of the control panel can be programmed for supervisory service. A common supervisory application would include
sprinkler water valve tamper switch monitoring. During a supervisory alarm, the integral sounder activates a rapidly pulsing tone
and the zone 2 red local alarm LED lights. In addition, the supervisory LED on the BMB will activate. During supervisory
trouble, the integral sounder activates a rapidly pulsing tone, zone 2 yellow local trouble LED lights and the system trouble relay
contacts transfer.
Remote T est (Drill)
A remote test (drill) function is provided for testing the 1500 System. Closing a listed normally-open switch connected to
terminals “SYS GND” and FIRE DRILL” (see Figure 5) will result in actuating both the alarm indicating circuits and the integral
sounder. The common alarm relay will not operate, nor will an optional remote notification circuit. Any alarm signaling devices
connected to the indicating circuits will be activated. During the test/drill, the indicating supervisory circuit will be tested as well,
resulting in the illumination of the indicating circuit fault LED’s and the system trouble LED. The integral sounder will sound a
slow intermittent signal.

Figure 7. Power Limited Routing
(Maximum voltage drop allowable: 2 VDC)
Installation Recommendations/Precautions
Note: The 1500 System is capable of power limited operation per NEC Article 760, Section C. All circuits are
power limitedexcept: CASE GND, TRB COM, TRB NO, ALM COM, ALM NC, and LEM terminals. Non-power
limited circuits must be separated from power limited circuits by a minimum of 1/4 inches (0.6cm). See Figure 7 for
one method of routing power limited wiring.
CAUTION
Do not route LEM field wires in close proximity of high voltage wiring. LEM filed wiring must not exceed 3280
feet (1000m).
V erify wire sizes are adequate for all indicating and initiating circuits. The maximum allowable initiating zone resistance is 100
Ohms. (Exception: When ESL 2-wire smoke detectors with integral sounders are used, maximum initating zone resistance is 50
Ohms. See T able 3.)
Many audible/visual signaling appliances cannot tolerate more than a 20 percent voltage drop from the specified device voltages.
See T able 4 to determine maximum distance for wire gauge used.
Incoming AC voltage should be stable at a nominal 120 volts. This is especially important in new construction where incoming
power may be high or unstable with temporary connections often causing large, inductive voltage spikes.
Ground the system properly. The AC imput, power supply/battery charger should use an isolated ground, not a conduit
ground. Do not connect this system to a conduit or green wire circuit that also is used to power resistance heating, motors, fans,
air conditioning equipment, or florescent lighting circuits since leakage currents into the ground return could damage system
components. A separate earth ground or cold water pipe with properly bypassed water meter should be used. Provide a separate
earth ground, if water mains are non-conductive.
Run signal wires separately. Most supervised circuits use voltage or current sensing circuits which are very sensitive to
induced voltages on the sensor wiring. Therefore, under no circumstances run AC power, speaker, public address, intercom, or
switch control wiring with inductive loads in the same conduit or in the immediate vicinity of the control wiring.
ESL 1500 Series Fire Alarm Control Panel

Page 15
Do not overlook adequate lightning protection. Lightning damage commonly occurs from three sources:
1.Through alarm loop wiring
2.Through AC power inputs
3.Through earth ground or power ground connections
The 1500 System has substantial lightning protection incorporated in all three areas. However, proper lightning protection for AC
power must be accomplished where the wire enters the building. Arrestor circuitry and earth grounding should be in accordance
with Article 250 of the National Electrical Code.
There is no known protective device available which is capable of protecting equipment from damage caused by “direct hit”
strikes of lightning due to the extremely high energy released (10 million to 100 million volts @ 10,000 to 30,000 amps).
However, line surges from indirect strikes can be minimized.
Additional protection is suggested in areas subject to above-average lightning activity or induced voltage spikes and fluctuations
due to power line load switching.
Field Wiring Checkout Procedures
Note: Make sure that AC and battery power are disconnected before proceeding.
1.Test all field wiring before connecting any equipment.
A. Make sure no unwanted voltages are present on circuit conductors and ground. They are a hazard and may prevent
proper system operation.
B. All wiring except those intentionally and permanently grounded must be tested for isolation from ground using an
insulation testing device such as a “Megger”.
Note: Caution must be exercised when using voltage generating test instruments such as a “Megger”. Damage
to equipment could result if the equipment is connected (wired) during wiring tests.
C. All wiring, other than those intentionally connected together, must be tested for conductor-to-conductor
isolation using an insulation testing device.
2.With each circuit pair short-circuited at the end of the circuit, measure circuit resistance with an ohmeter. Record the circuit
resistance of each circuit and store this data with the control panel. Loop resistance must be less than 100 ohms on
initiating zones.
3.Perform testing as described previously after any addition, deletion, or mechanical or electrical damage to the system
has occurred.
4.A periodic test should be performed in accordance with the schedules recommended in NFPA 72, Chapter 7, or more
frequently, if required by the authority having jurisdiction. Whenever possible a 100 percent test should be performed.
When less than a 100 percent test is performed, a record must be maintained of the devices tested each time, so different
devices are tested in subsequent tests.
Alarm Initiating Devices
This section describes how to field wire initiating devices such as smoke detectors, pull stations, and heat detectors. Refer to
Figure 5 for Class A (Style D) and Figure 6 for Class B (Style B) wiring.
Two-Wire Smoke Detectors, Heat Detectors, and Manual Pull Stations
•Connect only two-wire smoke detectors UL Listed as compatible to the 1500 Series Fire Control Panel. Refer to the
list of compatible detectors in Appendix A.
•Two-wire detectors receive their power direct from the zone terminals and transmit the alarm signal via the same wires. Be
certain to observe polarity when installing detectors.
•All initiating devices must be wired sequentially for proper supervision with the end-of-line resistor (2.7K Ohm 1/2 W)
installed after the last device. ESL has detectors available with EOL built in.
Four-Wire Smoke Detectors
•Four-wire detector power is shared with indicating circuits; do not exceed total power requirements of 1.5 Amps.
•Always supervise four-wire detector power with an end-of-line power supervisory device (ESL model 204-12/24V) after
the last unit.
See Figure 5 for Class A (Style D) wiring and Figure 6 for Class B (Style B) connection to the panel.

Sprinkler System Waterflow and Supervisory Devices
Normally open contact type waterflow alarm devices may be connected, along with conventional manual alarm stations or heat
detectors. All zones to which waterflow alarm devices are connected may be programmed so that the system alarm indicating
devices cannot be silenced. See Programming.
Supervisory signals for status reporting of waterflow control valves, supplies, etc. must be connected to a separate zone, and
programmed for supervisory status. Only Zone 2 can be programmed for this feature. See Programming.
Alarm Indicating Devices
Use only polarized UL Listed signaling devices rated for 24 VDC (see the list of devices in Appendix A). See Figure 5 for Class A
(Style Z) wiring and Figure 6 for Class B (Style Y) connection to the panel.
Note: Maximum indicating current per circuit is 1 Amp; however, total operating current cannot exceed 1.5 Amps.
Choose the correct wire size for maximum voltage drop of 2 VDC at the furthest device on the circuit (see Table 3).
Supplementary Alarm and Trouble Contacts are for power limited applications only.
Connecting Supplementary Contacts
Note: Supplementary Alarm and Trouble Contacts are for power limited applications only (see Installation Recommenda-
tions/Precautions). When supplementary contacts are connected to a power limited circuit, these outputs meet power limited
code and do not require separation.
Supplementary Alarm Contacts
Dry, Form C contacts are provided for controlling supplementary alarm functions from the BMB. Contacts are rated 2A @ 30
VDC resistive. Terminals are ALM COM, ALM NC, and ALM NO. Contacts transfer in alarm.
Supplementary Trouble Contacts
Dry, Form C contacts are provided for controlling supplementary fault functions from the BMB. Contacts are rated 2A @ 30
VDC resistive. Terminals are TRB COM, TRB NC, and TRB NO. The trouble relay is normally energized and will activate even
if both AC and battery power are removed.
.
Optional Zone Relay Module (ZRM)
Additional relays may be added using the optional ZRM-5. Make electrical connections using Figure 8. After connections are
made, use directions in Installing Optional ZRM and Snap Track to finish the installation.
Installing Optional ZRM and Snap Track
1Remove the protective tape from the adhesive mounting strip on the snap track supplied with the unit.
2Mount the snap track on the lower, right side of the cabinet. See Figure 9.
3Using the slots in the snap track as a template, drill two holes through the cabinet side wall, one near each end of the snap
track, using a #13, #14, #15, or 3/16” diameter drill and deburr.
4Install the supplied push rivets from the outside of the cabinet through both the cabinet side wall and the snap track, driving
the push pins flush with the rivet head. In semi-flush mounting installations, install the push rivets from the inside of the
cabinet.
5Complete electrical connections between the ZRM and the BMB before mounting it to the snap track. Then snap the
connected ZRM into the snap track with the terminals toward the front of the cabinet.
6Dress wire leads to comply with the requirements of the National Electrical Code, Article 760, Section C.

Note: When using remote annunciators other than the ESL 1500-RA-5A, be sure all circuits have a series resistance of at
least 1K ohm. Maximum current should be 15mA per zone.
The control unit can properly power oneremote annunciator. When a remote annunciator is used, both the BMB and ZEM
must be programmed to provide supervision. See Programming. The remote annunciator circuit is supervised as long as no other
devices are connected to the same terminals; otherwise, the devices will not be supervised. See Figure 10 for the wiring diagram.
1500-LEM
The Local Energy Module (LEM) trip circuit is designed to interface to a Listed Master Box with a local energy trip mechanism.
This optional module provides a supervised trip circuit from the 1500 system that activates the Master Box upon a system
alarm. Make connections as detailed in Figure 11.
For systems which include remote annunciation 1500-RA-5A, use Figure 10. Remove all power from the system before

Testing and System Checkout
Following installation and programming of the unit, a complete test of the entire system must be conducted to assure proper
operation. NFP A 72, National Fire Alarm Code should serve as the guide. Follow the recommended procedures, restoring all
switches and wiring to normal before proceeding to the next step.
Notify all building personnel and the fire department and monitoring facilities before and after system testing.
After testing all systems and restoring the panel to its normal operating condition, remove, and mount the 1500 Series Operating
Instructions, Appendix C, in a visible position near the control unit. In a household fire warning system, test weekly. Disconnect
the AC power source during testing. If after testing low battery conditions exists, replace the batteries.
Maintenance
Batteries
The 1500 Series control unit uses two sealed lead-acid batteries as the secondary power source. The batteries must be replaced if
the Low Battery LED remains on for more than 48 hours (indicates one or more of the battery cells are dead or the batteries will
not hold a charge). If the batteries are dead, replace with batteries of the same size and electrical rating, with a maximum size of
12V, 12 Amp hours and dimensions of 4” x 4” x 6” (10cm x 10cm x 15cm).
Note: When replacing batteries, always replace both batteries, even if only one appears dead. Typical battery life is 3 to 5
years, depending on usage. See the manufacturer’s specifications for the particular battery used. The battery charging ciruit
drops out if the charge falls below 15 VDC at batteries.
Fuses
The fuse located in the lower left corner of the BMB is provided for overcurrent protection. The fuse can be tested with an
ohmeter or visually inspected. If the fuse is blown, replace with a type 3AG, 1 1/4” (3cm) x 1/4” (0.6cm), 6 Amp Fast Blow fuse.
