2. The LEDs on the detector should light when the temperature at the detector reaches 135

C). If the LEDs fail
to light, check the power to the detector and the wiring in the detector base.

Detectors that fail these tests should be cleaned as described under MAINTENANCE and retested. If the detectors still fail
these tests they should be returned for repair.

MAINTENANCE
NOTE: Before cleaning notify the proper authorities that the system is undergoing maintenance, and therefore the system
will temporarily be out of service. Disable the loop or system undergoing maintenance to prevent unwanted
alarms.
It is recommended that the sensor be removed from its mounting base for easier cleaning and that sensors be cleaned at
least once a year. Use a vacuum cleaner to remove dust from the sensing chamber. See Figure 3.
