ESL 572NS Smoke Detector
communication between the control panel and the detector
before permanently mounting the detector as follows:
- Hold the detector up where you plan to install it.
- Press the Test button on the detector for 4 seconds. The
detector sends a signal to the control panel.
- At the control panel, verify the signal was received and the
RF signal strength is adequate. If no signal is received or the
RF signal is low, relocate the detector and retest.
6. Using the two screws and anchors provided, mount the base.
7. Attach the detector to the mounting base as follows:
- Line up the raised alignment tab on the lip of the detector
with the arrow on the mounting base. See Figure 4.
- Insert the smoke detector into the base and turn clockwise
approximately 15 degrees. It should snap firmly into place.
Important: The detector cannot be attached to the mounting
base if no batteries are installed.
8. Test the communication between the control panel and
detector as follows:
- Press the Test button on the alarm for 4 seconds. The
detector sends a signal to the control panel.
- At the control panel, verify that the signal was received.
9. Test the detector (see Smoke Testing the Detector) and if
applicable, reconnect the alarm notification appliances, service
release devices and extinguishing systems.
Important: The control panel alarm and all auxiliary functions
should be verified for a complete test of the system.
Smoke Testing the Detector
Smoke detectors should be tested in place annually using one of
the following methods:
A. Use Smoke! in a can® (product number SM-200), a canned
aerosol simulated smoke and follow the directions on the can.
B. Use the following steps to test the detector with smoke:
1. Hold a smoldering punk or cotton wick close to the smoke
entry openings.
2. Gently direct the smoke into the detector for 20 seconds or
until an alarm is indicated.
Be sure to extinguish the smoke source after testing! The
detector LED should stay on and an alarm should be indicated at
the control panel. Use the system reset switch to reset the
detector.

Testing the Detector Sensitivity
The detector provides a sensitivity level test mode that allows
you to check the detector sensitivity using the Test button
and the LED indicator on the detector as follows:
1. Press the Test button on the detector for 4 seconds. Once
the test starts, the detector LED flashes one to nine times.
2. Count the number of times the LED flashes and use the
following table to determine the status of the detector
sensitivity and what action to take, if any.

After the flashes, if the sensitivity is within limits and all
other tests pass, the detector goes into alarm and resets after
7 seconds.
If the sensitivity is not within limits, or an unserviceable
hardware fault has been detected, the detector LED extin-
guishes until the detector is serviced and the built-in transmit-
ter sends a CleanMe
or maintenance alert signal to the
control panel
