The alarm emits two short beeps to confirm that the pause function has been activated
and the test light double-flashes every 8th second. If you wish the pause function to
be shorter, press the test button again and the sensitivity will return to normal immediately.
This is confirmed by three short beeps.
Silencing undesired alarms
Pressing the test button of the detecting (primary) alarm after it has gone off will
silence the alarm immediately. The test light will continue to flash for as long as
the smoke level is higher than the threshold of the sensitivity reduction mentioned
above. The other smoke alarms will continue to sound for 25–40 seconds, but in a
different way (refer to Alarm/Pre-alarm, Memory).
7. Battery warning and battery replacement
The smoke alarm requires one 9 V battery (alkaline). A smoke alarm battery normally
lasts for over a year. When it is time to change the battery, the alarm will emit a short
beep every minute for up to 30 days (the alarm still works as normal during this time).
Each time a battery is connected, the smoke alarm performs an automatic self-test
of the detection system and sensitivity setting. The test light (an LED inside the test
button) comes on when the battery is connected and when the self-test is completed
the alarm emits a long beep and the test light turns off. The test light flashes every
8 seconds to indicate that the smoke alarm is in full working order.
Moreover, the smoke alarm performs an automatic self-test every day. If the detection
system is dirty and the alarm needs cleaning, the alarm emits 4 short beeps repeatedly.
If there is fault or interference in the detection system, the alarm emits 2 or 3 short
beeps. Technical faults can also be caused by external interference form electrical
equipment, strong light sources, etc. Cleaning or moving the alarm might help alleviate
the fault, otherwise the alarm should be sent in for a service. Please note that
the signals for the activation and deactivation of the pause function are 2 short and
3 short beeps respectively (refer to Pause function).
Handy hint: If your battery does not last for a whole year, the reason may be due to
another radio system close by which is working on the same frequency range.
This problem can normally only be solved if the interfering radio system can be
localised and deactivated.
8. Test and maintenance
The test light flashes every 8 seconds to indicate that the alarm is working correctly.
You can also test each alarm personally by giving the test button a quick press.
The alarm should sound and all functions (except radio transmission) are tested.
At the same time, the smoke alarm is set to pause mode and two short beeps are
emitted (refer to Pause function).
