TESTING WITH CARBON MONOXIDE
The unit checks for CO every 4 seconds and as soon
as it detects CO, it flashes the red light (as per Table
B on page 4) to confirm that is detecting CO gas.
Alternatively:
Pressing the Test/Hush button causes the unit to check
for CO - this is the
Fast CO Test Mode
. This eliminates
the long wait normally required (e.g. up to 90 minutes at
55ppm CO and up to 3 minutes at 330ppm CO).
The unit can be tested with CO by using one of the
kits that comes with CO either in a glass phial or
aerosol can. Follow the instructions on the kit but be
sure to press the Test/Hush button to speed up the
CO sampling
directly
after you expose the unit to
the CO. It is best if possible to inject the CO gas into
the gas entry holes (see
Figure 4
). When it senses
the CO it will give 3 beeps and the red light will flash
as per Table B. It then automatically resets to normal
mode. (If unit fails to respond, press the Test/Hush
button again as gas can take some seconds to enter
sensor).
The
Fast CO Test Mode
normally does not activate
the memory function unless a high level of CO
remains in the sensor for a few minutes. (This can
be checked by pressing the Test/Hush button. If the
red light flashes continuously (indicating CO was
detected), hold the Test/Hush button for 20 seconds
until the red light stops flashing as the memory
resets).
7. HOW TO DISTINGUISH BETWEEN CO
ALARM & SMOKE ALARM WARNINGS
The CO Alarm has a distinctive on-off sound of 3
pulses followed by a pause, as compared with a
typical Smoke/Heat Alarm which has a rapid pulsing
sound.
In addition, when your CO Alarm is sounding, the red
alarm light on the cover will be flashing.
Testing both your CO Alarms and Smoke/Heat
Alarms weekly will help you and your family to clearly
distinguish between them in an emergency.
If CO Alarms and Smoke/Heat Alarms are
interconnected (and are all sounding), press the
LOCATE switch on the Ei1529RC Remote Control
to leave just the alarm that has triggered the system
sounding.
8. MAINTENANCE
Clean the outside case by occasionally wiping with a
clean damp cloth (disconnect the mains supply at the
distribution/fuse board first). Do not use any cleaning
agents, bleaches, detergents or polishes, including
those in aerosol cans. Avoid spraying air fresheners,
hair spray, paint or other aerosols near the CO
Alarm. Do not place air fresheners near the unit.
Use the narrow nozzle of a vacuum cleaner to
remove dust and other contamination from the gas
entry holes in the cover of the Alarm to ensure CO
gas can reach the sensor.
