Smoke Alarm/Detector
56X - UL 217 Smoke Alarm Series
57X - UL 268 Smoke Detector Series
Installation Instructions
Description
The ESL smoke alarm/detector is a Learn Mode, wireless
sensor that uses photoelectric technology with a self
contained alarm siren, a low battery annunciator, and a
status LED. The smoke alarm/detector is part of a security/
fire alarm system and communicates with the system
control panel.
Depending on the model, the smoke alarm/detector
provides the following features:
Self-diagnostics. The ESL Universal Series smokes monitor
their own sensitivity and operational status. If the smoke
alarm/detector drifts out of the UL listed sensitivity range
or fails internal diagnostics, it extinguishes its LED and
sends a trouble signal to the control panel.
Base tamper switch sends a trouble signal transmission to
the control panel when the smoke alarm/detector is
removed from its mounting base.
Integrated fixed 135°F temperature and rate of rise heat
detector trips an alarm based on high temperature detected
or rapidly rising temperature rate (15° minimum) (models
562STU and 572STU only).
Transmitted Signal Outputs
Depending on the model, the smoke alarm/detector
transmits the following signals to the control panel:
• Alarm
• Alarm restore
• T amper
• Low battery
• Trouble signal
• Supervisory

Selecting a Location
Selecting a suitable location is critical to the operation of
smoke alarms/detectors. This equipment should be
installed in accordance with the National Fire Protection
Association’s (NFPA) Standard 72. See Figure 2.
A-8-1.2.1.a Where to Locate the Required Smoke
Alarms/Detectors in Existing Construction.
The major threat from fire in a family living unit occurs at
night when everyone is asleep. The principal threat to
persons in sleeping areas comes from fires in the
remainder of the unit. Therefore, a smoke alarm/
detector(s) is best located between the bedroom areas
and the rest of the unit. In units with only one bedroom
area on one floor, the smoke alarm/detector(s) should be
located as shown in Figure 2 A.
In family living units with more than one bedroom area or
with more than one floor, more than one smoke alarm/
detector is required, as shown in Figure 2 B.
In addition to smoke alarms/detectors outside of the
sleeping areas, the installation of a smoke alarm/detector
on each additional story of the family living unit,
including the basement, is required. These installations
are shown in Figure 2 C. The living area smoke alarm/
detector should be installed in the living room or near
the stairway to the upper level, or in both locations. The
basement smoke alarm/detector should be installed in
close proximity to the stairway leading to the floor
above. Where installed on an open-joisted ceiling, the
alarm/detector should be placed on the bottom of the
joists. The detector should be positioned relative to the
stairway to intercept smoke coming from a fire in the
basement before the smoke enters the stairway.

A-8-1.2.1.c Are More Smoke Alarms/Detectors Desirable?
The required number of smoke alarms/detectors might not
provide reliable early warning protection for those areas
separated by a door from the areas protected by the
required smoke alarms/detectors. For this reason, it is
recommended that the householder consider the use of
additional smoke alarms/detectors for those areas for
increased protection. The additional areas include the
basement, bedrooms, dining room, furnace room, utility
room, and hallways not protected by the required smoke
alarms/detectors. The installation of smoke alarms/detectors in kitchens, attics (finished or unfinished), or garages
is not normally recommended, as these locations occasionally experience conditions that can result in improper
operation.

Important !
Regulations pertaining to smoke alarm/detector installations vary from state to state. For more information, contact
your local fire department or local authority having
jurisdiction.
In addition to NFP A 72, use the following location guidelines to optimize performance and reduce the chance of
false alarms from the alarm/detector:
• Locate ceiling-mounted smoke alarms/detectors in the
center of a room or hallway at least 4 inches from any
walls or partitions.
• Locate wall-mounted smoke alarms/detectors so the top
of the alarms/detector is 4 to 12 inches below the ceiling.
• Locate in a suitable environment as follows:
- T emperature between 40°F (4.4°C) and 100°F (37.8°C)
- Humidity between 0 and 95% non-condensing
• Locate away from air conditioners, heating registers and
any other ventilation source that may interfere with
smoke entering the alarm/detector.
• Mount smoke alarms/detectors on a firm permanent
surface, typically a stud or metal runner.
• Locate away from large metallic objects.
A-8-1.2.1.b Where to Locate the Required Smoke Alarms/
Detectors in New Construction.
All of the smoke alarms/detectors specified in A-8-1.2.1.a for
existing construction are required and, in addition, a smoke
alarm/detector is required in each bedroom.

Installing the Alarm/Detector
1 . Slide the battery compartment cover away from the alarm/
detector to unsnap it and lift it off. See Figure 3.
2 . Observing proper polarity, insert the two lithium batteries
provided into the alarm/detector battery compartment and
replace the battery compartment cover.
3. Making sure that the unit is removed from its base, put the
panel in program mode/Learn Mode.
4 . Remove the red plastic dust cover from the alarm/detector.
The alarm/detector is shipped with a dust cover for
protection on construction sites with dusty environments.
5. Press the test/silence button until the panel indicates that
the sensor has been enrolled.
6 . Disconnect the alarm notification appliances, service
release devices, and extinguishing systems and test the
communication between the control panel and each smoke
alarm/detector before permanently mounting the alarms/
detectors as follows:
- Press the test/silence button on the alarm/detector
for 2 seconds. The alarm/detector sends a test signal
to the control panel.
- At the control panel, verify the test signal was received
and the RF signal strength is adequate. If no signal is
received or the RF signal is low, relocate the alarm/detector
and retest.
7. Using the two screws and anchors provided, mount
the base.
8. Attach the alarm/detector to the mounting base as
follows:
- Line up the raised tab on the lip of the alarm/detector
with the slot on the lip of the mounting base.
See Figure 3.
- Insert the alarm/detector into the base and turn clockwise
approximately 15 degrees. It should snap firmly into place.
9. Test the communication between the control panel
and each smoke alarm/detector as follows:
- One at a time, press the test/silence button on the
alarm/detector for 2 seconds. The alarm/detector sends a
test signal to the control panel.
- At the control panel, verify the test signal was received.
10. Test each alarm/detector (see Smoke Testing the
Alarm/Detector) and reconnect all alarm notification
appliances, service release devices, and extinguishing
systems.

Smoke Testing the Alarm/Detector
Smoke alarms/detectors should be tested in place annually
using smoke or Smoke! in a Can. Follow the instructions on
the canned smoke or use the following steps to test the
alarm/detector with smoke:
1 . Hold a smoldering punk or cotton wick close to the
smoke entry openings.
2 . Gently direct the smoke into the alarm/detector for 20
seconds or until an alarm is indicated.
BE SURE TO PROPERL Y EXTINGUISH THE SMOKE
SOURCE AFTER TESTING! The alarm/detector LED should
remain on while the built-in transmitter sends an alarm
signal to the control panel. The alarm/detector will sound a
temporal rhythm until the test/silence button is pressed.
The alarm/detector automatically resets when smoke is no
longer present.
Important !
The control panel alarm and all auxiliary functions should be
verified for a complete test of the system.
