ESL Universal Wireless Smoke Alarm/Detector
Figure 4 - Removing Alarm/Detector Cap
panel to determine what action to take. If the unit has a
hardware fault, it will stop reporting supervision signals to
the panel.
Attaching and Removing
the Alarm/Detector
To remove the alarm/detector from the mounting base,
grasp the alarm/detector and turn it counterclockwise
approximately 15 degrees. The alarm/detector should snap
off of the mounting base.
Attach the smoke alarm/detector to its mounting base
as follows:
- Line up the raised tab on the lip of the smoke alarm/
detector with slot on the lip of the mounting base. See
Figure 3.
- Insert the smoke alarm/detector into the base and turn
clockwise approximately 15 degrees. It should snap firmly
into place.
When to Replace the Batteries
When the batteries are low, the alarm/detector sends a low
battery signal to the control panel, waits several days and
then chirps every 30 seconds until the batteries are re-
placed. The sounder can be silenced for 24 hours by
pushing the test/silence button. See Specifications for
battery type list.
Testing the Alarm/Detector
Sensitivity
The ESL Universal Wireless Series provides a sensitivity
level test mode that allows you to check the alarm/detector
sensitivity using the test/silence button and the LED
indicator on the alarm/detector as follows:
1. Press the test/silence button on the alarm/detector for 2
seconds. The alarm/detector performs a test, and the
LED flashes one to nine times.
2. Count the number of LED flashes and use the following
table to determine the status of the alarm/detector
sensitivity and what action to take, if any.
Understanding the Test/Silence
Button
Depending on the model, the test/silence button on the
smoke alarm/detector performs three functions as follows:
Testing = Press the test/silence button for 2 seconds. The
alarm/detector performs a sounder test (UL 217 models
only) and a sensitivity test and then sends a test signal to
the control panel.
Silence alarm = Press to silence the sounder during an
alarm. After a few minutes, the sounder will resume low
battery if smoke is still present.
Silence low battery chirp = Press to silence a low battery
chirp. The low battery chirp resumes after 24 hours if the
condition is not corrected.
Understanding the LED
The LED on the ESl Universal Wireless Series indicates the
status of the alarm/detector as follows:
FLASHING = Flashes every 9 seconds to indicate normal
operation.
ON = Detects smoke, sending an alarm.
OFF = Trouble. Maintenance is required. Check the control
After the flashes, if the sensitivity is within limits and all
other tests pass, the smoke alarm/detector goes into
alarm and sends a test signal to the panel, then resets after
5 seconds.
If the sensitivity is not within limits, or an unserviceable
hardware fault is detected, the LED extinguishes until the
alarm/detector is serviced and the built-in transmitter sends
a trouble signal to the control panel.
