M AINTAINING THE S YSTEM
Replacing Batteries
IMPORTANT: Always press the reset button and test the transmitter after changing batteries.
The sensor is powered by two 3 VDC lithium batteries. When the system indicates the sensor has a low battery, replace the batteries immediately. You must remove
the batteries to reset the low battery signal before installing new batteries. Important: Replace both batteries when the sensor or panel notifies you that a battery
is low. Recommended battery replacement is PANASONIC CR123A. Use of any other batteries may present a risk of fire or explosion. To prevent a low battery
condition, you must install the batteries exactly as described.
CAUTION: Dispose of used batteries promptly according to the manufacturer’s instructions and/or local authorities. Batteries can explode or cause burns if
disassembled, recharged, or exposed to fire or high temperature. Keep away from children.
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 45 seconds until the batteries are exhausted. Press and release the test button to silence the low battery beeps
for 24 hours. Constant exposure to high or low temperatures or high humidity may reduce battery life. Always test the system after replacing the batteries.
Cleaning
Clean the sensor cover with a dry or damp cloth as needed to keep it free from dust and dirt. Clean the sensor interior at least once each year. This requires
replacing the optical chamber. Use only ESL model 211 Optical Chambers for replacement.
To o clean the senso or chamber:
(1) Place the panel in sensor test mode. (2) Remove the sensor from the mounting base.
(3) Remove the batteries. (4) Slide a flat-blade screwdriver in the slot on the sensor cap
and gently push the handle down to pry the cap off. See Figure 8. (5) Squeeze the existing
optical chamber where indicated and pull it up and away from the sensor and discard. See
Figure 11. (6) Blow out or use a soft-bristled brush to remove dust and dirt from the
smoke chamber base. (7) Align the new optical chamber with the base and snap down into
place. (8) Replace the sensor cap by lining the cap up with the sensor, then press the cap
onto the sensor and turn clockwise approximately 15 degrees. It should snap firmly into
place. (9) Observing the proper polarity, reinstall the batteries and replace the battery
cover. (10) Reattach the sensor to the mounting base. See Figure 10. (11) Test the
sensitivity as described below.
Note: The base will not fit properly if the batteries are not installed.

EPORTING
As the factory default condition, the FA202 combines the CleanMe signal with its Low Battery signal. If the control panel indicates a Low Battery trouble
condition, this should be interpreted as a Maintenance Needed trouble indication. (The battery may be fine, but the detector needs cleaning.) If this multiple-
condition panel indication is not desired, wireless reporting of the CleanMe status can be disabled by moving the jumper on the CleanMe 3-pin header to the
inactive position (see Figure 12). When this is done, only a Low Battery signal will be sent from the detector, and only a Low Battery trouble condition reported
at the panel. NOTE: Even if CleanMe notification is disabled, the sensitivity test will still indicate sensor condition.
