will stop when the button is released. Pressing the test button
simulates the effect of smoke or heat during a real fire and is
the best way to ensure the Alarm is operating correctly.
WARNING: DO NOT TEST WITH FLAME
This can set fire to the Alarm and damage the house
We do not recommend testing with smoke or heat as the
results can be misleading unless special apparatus is used.
(iii) Check for any sign of contamination such as cobwebs or
dust and clean the alarm as described in the “CLEANING
YOUR ALARM” section on page 6, if necessary.
(iv) Interconnected Alarms only - Test the first unit by
pressing the button for 10 seconds. All the units should alarm
within 10 seconds of the first horn sounding. The red light on
the first unit only will flash about once a second. Check all the
other units similarly.
(v) Check the functioning of the mains battery back-up directly
after installation and then at least yearly as follows:
- Turn off the mains power at the distribution board and check
that the green indicator light is extinguished.
- Press the test button and ensure the horn sounds loudly for
10 seconds.
Turn on the mains supply at the distribution board only if the
unit passes the above test.
Note: If the mains is disconnected and the battery is almost
depleted the unit will beep every 40 seconds for at least 30 days.
(vi) Monitor the alarm over a short period of time for any
beeps.
5.1 If the unit is beeping
The Alarm automatically monitors the battery every 40
seconds to ensure that it is satisfactory. If it is depleted it will
give a short beep every 40 seconds.
Models Ei141, Ei144 & Ei146 only
Before replacing the battery, check that the beeps are not
due to one of the following:
(i) battery snaps not connected properly.
(ii) On the Optical Smoke Alarm only (Ei146) if the unit
beeps and the red light does not flash at the same time it
indicates a problem with the smoke chamber - see
“CLEANING YOUR ALARM” section on page 6.
(iii) If the beeps have continued for over 20 minutes (and
the other causes of beeps have been ruled out - see
“TROUBLESHOOTING” section on page 11) the battery
must be replaced.
See “CHANGING THE BATTERY” section on page 4.
