changing them! Always test the alarm immediately after returning from holiday or after a
longer period of absence. Under the test button, there is a red activity LED. When this
LED is enabled (see page 7) it flashes about once every minute. This shows that the
batteries are correctly connected. If the alarm does not sound when testing, the batteries
must be replaced. The alarm should be dusted and cleaned regularly with a slightly damp
cloth. In connection with annual battery change or when required, for example after a false
alarm, clean and vacuum the alarm carefully using a soft brush.
CAUTION:
Do not paint the alarm.
The batteries last approximately 24 months. About a month before the batteries are
completely flat, the alarm emits a short chirp once a minute. This is the signal that the
batteries need changing. The alarm works as normal during this time. The batteries
should be an alkaline 1.5 Volt AA size. Use good quality batteries: Duracell Procell
MN1500 or Eveready Energizer EN91. Always test the alarm after changing the batteries.
Notes:
1. Wait 60s between removing the old batteries and inserting the new batteries.
2. Do not pull on the catches between the batteries to try to force them out.
3. Do not try to close the battery compartment without the batteries present. The product
is designed to prevent this.
Service
If the sounder chirps once every 10 seconds and the activity LED is flashing once a sec-
ond then a fault has occurred. Remove the old batteries, wait 60s, and then fit new
batteries. Check that the activity LED is working normally.
