Smoke alarm 1
01 January 0001
There may be two reasons for a chirping or beeping smoke alarm.
1. Low battery
-
If the alarm starts beeping once every 40s, the backup battery needs replacing.
-
If you wish to replace the battery later, press the test/hush button to snooze for 10hrs.
2. False alarm
- If the smoke alarms go into alarm with no smoke present, firstly identify the unit which has triggered.
- While alarming, look for the smoke alarm with the flashing RED LED.
- If the alarms have stopped sounding before you could identify the alarm that triggered, look for the alarm which has the RED LED flashing once every 2 seconds. (it will do this for up to 72hrs)
- Vacuum this unit to clean dust or cobwebs. If later it still false alarms, call an electrician to check the alarm.
