Attaching the sensor to the base:
Attach the sensor to the base as follows:
1.
Line up the raised tab on the lip of the sensor with the
slot on the lip of the mounting base.
Slot and raised tab
Figure 8. Sensor-to-Base Alignment
2.
Attach the sensor onto the base and turn clockwise
approximately 15 degrees. It should snap firmly
into place.
Testing
Test each smoke sensor every week to verify that its siren
and signal integrity are adequate. Refer to the specific panel
installation instructions for system response.
Sensor Test
1.
Put the panel in the Dealer or User Sensor Test mode.
2.
Press and hold the test/silence button on the detector
for 2 seconds, then release it.
After a slight delay (about 10 seconds), the LED turns
on and the built-in sounder emits one temporal
3 pattern (3 beeps).
Note
The model 60-849-95 (UL 268 version) does not produce
any sound when the test/silence button is pressed.
3.
Listen for the appropriate response from system
sirens to determine signal integrity from the sensor
to the panel (refer to the specific panel installation
instructions).
4.
Exit from Dealer or User Sensor Test mode.
Smoke Test
Smoke detectors should be tested in place annually using
canned aerosol simulated smoke (Smoke! in a Can, ESL Part
No. SM-200). Follow the instructions on the can.
CAUTION
To avoid a fire department dispatch, contact the central
monitoring station or put the system into sensor test
mode before activating the sensor using this method.
The LED should remain on while the built-in transmitter
sends an alarm signal to the control panel. The sensor
produces a temporal 3 beeping pattern until the test/silence
4
button is pressed (model 60-848-95 only). The sensor
automatically resets when smoke is no longer present.
A sensor that fails to activate with either the sensor or
smoke test may require cleaning. If a sensor still fails to
activate after cleaning, return the unit for service.
Sensitivity Test
Each smoke sensor includes a sensitivity level test mode
that lets you check the sensitivity using the test/silence
button and the LED as follows:

Maintaining the System
Replacing Batteries
When the batteries are low, the sensor transmits a low
battery signal for at least 7 days, allowing the monitoring
company time to contact the customer for service.
After 10 days, the sensor will chirp every 30 seconds until
the batteries are exhausted. Press and release the test/
silence button to silence the low battery beeps for 24
hours.
Constant exposure to high or low temperatures or high
humidity may reduce battery life. Replace both batteries
when the sensor or panel notifies you that the batteries are
low. Always test the system after replacing the batteries.
Press and hold the test/silence button for 2 seconds,
then release it. The LED flashes one to nine times.
Count the number of LED flashes and use the
following table to determine the status of the sensor
sensitivity and what action to take, if any.
