5.2.8. TESTING WITH CARBON MONOXIDE

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. It is best if possible to inject the CO gas into the gas entry holes (see Figure 4).

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 7) to

confirm that is detecting CO gas.

Testing with CO 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 the memory has been activated -

therefore, hold the Test/Hush button for 20 seconds until the red light stops flashing as the memory resets).

6. 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. Note: When the Test Button is pressed on the CO Alarm the

red alarm light does not flash unless the CO memory was activated.

If CO Alarms and Smoke/Heat Alarms are interconnected (and are all sounding), press the LOCATE switch

on the Ei1529RC or Ei411H3 Remote Control to leave just the alarm that has triggered the system sounding.

(Note: CO Alarms and Smoke/Heat Alarms from other manufacturers may sound differently).

7. 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.
