9. When the system is alarm free, check each detector to
ensure that the green LED indicator flashes approximately
every eight seconds. This verifies the detector is receiving
power and operating properly.
5.2 Test Each Detector
Test each detector to ensure it causes a control panel alarm.
Reset the control panel after each test.
5.2.1 Activate an Alarm at Each Detector
To cause heat detectors to alarm either:
– Activate the internal reed switch by placing a magnet
horizontally against the T mark on the mounting skirt and
holding it there for three consecutive LED flashes, or
– Expose the thermistor to a heat source such as a hair dryer
or a shielded heat lamp until the detector alarms and the
alarm LED lights .
To cause smoke detectors to alarm either:
– Activate the internal reed switch by placing a magnet
horizontally against the T mark on the mounting skirt and
holding it there for three consecutive LED flashes, or
– Use a UL Listed aerosol smoke detector tester to simulate
an alarm. Follow the instructions provided with the aerosol
smoke detector tester.
5.2.2 Reset the Control Panel
When a detector alarms, the red LED indicator activates and
latches into the ON position. Clear the alarm by momentarily
removing power before proceeding to the next detector.
i
NOTE! If a heat detector LED flashes at a rate of
4 flashes/sec, the detector is either cold (below +32°F
[0°C]), out of sensitivity range, or defective. If a smoke
detector flashes at a rate of 4 flashes/sec, it is either out
of sensitivity range or defective.
