b. Testing
• Utilise the test button to test the alarm. Do not use naked flames as this does not repli-
cate smoke and may cause physical damage to the alarm or ignite combustible materi-
als and start a structure fire.
Test all your alarms weekly – remember they are life saving devices, protecting the
family and home.
Press and hold the test button until the alarm sounds. All interconnected alarms will
also sound. (Do not stand too close to the alarm during testing – hearing may be dam-
aged.)
c. Hush Button
• This feature temporarily desensitises the alarm circuit for approximately 7 minutes. This fea-
ture is to be used only when a known alarm condition, such as fumes from cooking, activates
the alarm. The alarm is desensitised by pushing the "HUSH" button on the alarm cover. If the
smoke is not too dense, the alarm will silence immediately and "chirp" every 30-40 seconds
for approximately 7 minutes. This indicates that the alarm is in a temporarily desensitised
condition. The alarm will automatically reset after approximately 7 minutes and sound the
alarm if particles of combustion are still present. The "HUSH" feature can be used repeatedly
until the air has been cleared of the condition causing the alarm. When several alarms are
interconnected, pushing the "Hush" button will hush all but the triggering alarm. The trigger-
ing alarm is signified by a rapidly flashing red LED. For safety reasons, the triggering alarm
signal can only be silenced by activating the Hush button on the unit.
Note: Dense smoke will override the hush control feature and sound a continuous alarm.
Caution: Before using the alarm hush feature, identify the source of the smoke and be
certain a safe condition exists. (On heat alarms with hush, the alarms sensor has detected
a high temperature – e.g. 57°C. Check for possible causes
carefully.)
d. Nuisance Alarms
Warning: Persistent nuisance alarms indicates incorrect type and/or siting of alarm.
Review with your installer or Landlord after cleaning as described in Section 7
(Maintenance).

5. Battery Checking/Changing*

Loose Battery Models
a. Low Battery Indicator (AC models with loose battery only)
If you hear the alarm chirp continuously every 30-40 seconds at the same time as the
led flashes (and have not just pressed the hush button) it indicates the battery voltage is
at an unacceptably low level. Replace the battery at the next possible opportunity.
b. Battery Change
i. Firstly isolate the mains supply at the consumer unit by identifying the appropriate
circuit. This may be a dedicated fuse marked "Fire/Smoke Alarms" or with a symbol
such as
