cobwebs or dust and clean the Alarm as described in
the “cleaning” section if necessary.
5. 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. On releasing the button the
local Alarm will stop sounding immediately and the
remote Alarms will stop sounding approximately 3
seconds later (if testing using RF interconnection
this could take slightly longer). This will verify that
the interconnect is working. Check all the other units
similarly.
6. 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.
7. Monitor the Alarm over a short period of time for any
beeps.
Switching off Mains for long periods
If the premises are regularly being left without mains
power for long periods the Smoke/Heat Alarms should be
removed from their mounting plates to prevent the batteries
becoming fully depleted. (This is sometimes done with
holiday homes which are only occupied in the Summer).
The Alarms must be re-attached to the mounting plates
when the premises are re-occupied.
Note: Long term storage (over 1 year) can damage the
batteries such that they will not recharge when the units
are re-connected to the mains supply.
If the unit is beeping
Check that the green mains power light is on. If it is off
the Alarm is not receiving mains power and is being
powered from its internal back-up cells. The beeps
indicate that they are depleted. The cells are not
replaceable. Re-connect the mains, check fuse, circuit
breakers and wiring. If in doubt contact a licensed
electrician. The beeps should cease within 2 hours as
the cells charge up. Fully charged, the cells will provide
up to 6 months back-up without mains power.
On the Optical Smoke Alarm only (EIB166e or
EIB166e-DHHS) 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” section.
If all of the above possible causes of beeps have been
ruled out, but the beeping has still persisted for over 2
hours with the green light on - the rechargeable cells
may be defective. The Smoke / Heat Alarm must be
returned to the manufacturer for repair or replacement -
see “Service and Guarantee” section.
