6. TESTING
1.
Regularly check that the green mains power light is
on. The unit cannot detect CO if the mains power is off
and the rechargeable battery back-up is depleted. (If it
is off check circuit breakers, fuses, wiring etc).
2.
Test the unit weekly by pressing the Test/Hush
button. Hold the Test button (for up to 10 seconds)
until the horn sounds for over 5 seconds. This will
help to familiarise you and your family with the
distinctive on-off sound of the CO Alarm. This test
checks that the electronics and horn are working
correctly. If units are interconnected, button test
each unit in turn and check all interconnected units
alarm. (If the red alarm light flashes when the button
is pressed, see 2.4 “CO ALARM MEMORY” on page
8). Alternatively, if an Ei1529RC Remote Control is
in the system the unit can be tested by pressing the
Test switch on the Ei1529RC. This is equivalent to
pressing the Test button on the Alarm.
3.
If the Alarm gives a short beep and the amber
fault light flashes every 40 seconds it means the
self-checking circuit has detected a fault. Press and
hold the Test/Hush button. If the amber light flashes
without the horn sounding, the sensor is faulty. On
the Ei261DENRC the display will show
SF
indicating
S
ensor
F
aulty.
4.
If the Alarm fails to operate when the Test/Hush
button is pressed, switch off the mains supply at the
distribution fuse board and remove unit from mounting
plate for 3 minutes. Put unit back on mounting plate.
Reconnect the mains and test again. (This procedure
resets the microprocessor in the unit).
5.
If the unit beeps every 40 seconds (without a
light flash) it means the battery is depleted. (On the
Ei261DENRC with depleted cells, the display will
show
CP
to remind you to
C
onnect mains
P
ower).
Connect mains power (ensure green light is on) to
allow cells to charge.
6.
Once a year check the
rechargeable battery
by
switching off the mains supply and pressing the Test
/Hush button for 10 seconds. The horn should sound
loudly. Reconnect the mains supply.
If the CO Alarm fails any of the above tests it must
be replaced immediately (see “GETTING YOUR CO
ALARM SERVICED”).
END OF LIFE (EOL)
When in EOL condition, the Alarm will flash yellow
and beep 3 times every 40 seconds. The Alarm
has reached the end of its usable life and must be
replaced. Display Alarms will also indicate ‘EL’ on
the screen. Pressing the Test button while the Alarm
has entered the EOL condition will also cause the
Alarm to flash yellow and beep 3 times, this will then
be followed by the normal test sound while the test
button continues to be pressed.
N.B.
When the test button is released the Alarm will
enter a 30 day supression of the EOL indicator, i.e.
the 3 yellow flashes with beeps will stop for a 30 day
period. Any subsequent test button presses during
this 30 day period will be as normal (normal test
sound).
