Installation and Operating Instructions

restore activations.
NOTE: The detector will not enter an alarm state when other internal faults are present.
Owner's Instructions
Testing the detector
Follow the test procedure described here or contact your dealer or installer for test in g
instructions. It is recommended to test the entire alarm system at least once a week to
verify the operation of all system functions.
Detector unit test
To test the detector only, press and hold the Test button for less than five seconds. The
sounder chirps to indicate that the unit is functioning correctly. When the button is released,
the chirping ceases. If this does not occur, ensure battery is the correct type, in good
condition, and installed correctly. To test the detector and the alarm panel together, press
and hold the Test button for more than five seconds. An alarm signal is sent to the control
panel.
Detector test
Before you test, complete the following steps:
1. Insert the battery and then mount the detector on the backplate.
2. After the battery is inserted, wait two minutes before testing. The detector enters into
Local Diagnostic Test mode for 15 minutes.
3. It is recommended to perform the Periodic Test and use either the Installer code
(Installer Diagnostic mode) or the User code (User Diagnostic mode) to test.
CAUTION: The diagnostic test cannot be performed when the tamper is open.
To perform a detector test, press and hold the Test button for less than 5 seconds. When the
button is released, the Red LED flashes, followed by two loud alarm beeps.
In test mode, the detector tests heat and battery functions.
If the detector is in diagnostic mode, the detector performs the diagnostic test as described
below.
Diagnostic test
The following sequence of events occur during a diagnostic test:
A. The detector performs a link quality test.
Note: The detector must be in local or diagnostic mode to perform the link quality test.
In diagnostic mode, if you press the Test button for more than 10 seconds, an alarm
message is sent to the panel and a Temporal-3 alarm signal is sounded. After this
sequence is completed, the device enters Alarm in Memory mode. To preserve
battery life, the device clears the indication after 30 minutes if it has not been cleared
on the panel.
B. If you press the test button for 4 seconds and then release, at the end of the
diagnostic test the LED blinks three times. The following table indicates the received
signal strength.

IMPORTANT! Reliable reception must be confirmed. Therefore, poor signal strength is
not acceptable. If you receive a poor signal from the device, re-locate it and re-test until
a good or strong signal strength is received. See the alarm system installation manual
for detailed diagnostic tests. For UL/CUL installations, the test results must be strong.
Owner’s Maintenance
This detector is designed to require minimum maintenance. If the case is greasy, wipe
gently with a soft cloth slightly dampened with soapy water.
Never disassemble the detector; there are no user serviceable parts inside the unit.
You may only remove the backplate to replace the battery if not serviced by an
installer. When replacing the battery, follow the instructions specified in the Installation
Instructions.
Never paint the unit. Paint may interfere with the proper operation of the unit. If you
are planning renovations or repainting, take precautions to avo id dust, paint or
chemical contamination to the detector.
Installation, testing, and maintenance procedures shall be in accordance with NFPA72.
