6. Trouble Shooting
6.1 False Alarms
In the event of a "false alarm" - it is imperative that the cause is determined and
corrective action taken.
Condition: False Alarm - System is fully activated
- Red Alarm LED 'ON'
Step 1. Operate the LOCATE switch so that it is illuminated and turn key to
FIRE. This silences the panel and all the smoke alarms except the one
which initiated the alarm. Listen and you will be able to determine where
this smoke alarm is located.
NOTE: The panel does not latch in alarm (depends on system set up) ,
so when the smoke alarm resets, the panel resets.
Step 2. Try to determine the cause of the alarm It may be a "simulated
condition" such as dust, steam, insect spray, cooking fumes, gas heater
etc. Fan the smoke alarm vigorously with a newspaper or cloth to try and
clear any contaminant from inside the sensor. If the smoke alarm
silences return to the panel and go to Step 3..
If the Smoke Alarm cannot be silenced pull open its cover and find
the isolation switch as shown in the diagram below. (Some alarms
may not have this type of switch; in that case, simply leave the cover
open). Slide the switch to the OFF position. You have deactivated the
alarm and it will no longer be capable of sensing smoke. Also, any
interconnected smoke alarms between this one and the smoke alarm at
the end of the line on the zone will not be able to send an alarm signal
back to the panel. Call the service technician responsible
immediately. Return to the Control Panel and ensure that all switches
are in the normal position. A fault will be indicated. Activate the Sounder
Silence switch.
