If a Remote Control Switch is not fitted, find the alarm with its red alarm light flashing rapidly – if it is a
Carbon Monoxide Alarm follow the instructions on page 4.
If it is a fire, evacuate everybody from the premises, closing all doors as you leave, call the Fire Brigade
and follow the other emergency instructions supplied with your Smoke/Heat Alarm.
(Note: When all the alarms are sounding you must not press the hush button on the Ei411H until you
know which unit caused the alarm).
5.2 Testing the System
5.2.1. 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).
5.2.2. Test the unit weekly by pressing the Test/Hush button. Hold the button (for up to 10 seconds)
until the horn sounds for over 5 seconds & the RadioLINK Indicator light turns red for about 3.5 seconds
(the horn will pause during the RF transmission). Any other interconnected devices should now sound.
Release the Test/Hush button. The local alarm will cease and you should then be able to hear any other
alarms sounding in the distance (if any of the alarms do not sound - see Section 14 Troubleshooting.
5.2.3. Pressing the Test/Hush button 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 the red
alarm light flashes when the button is pressed, see Section 2.4 "CO ALARM MEMORY"). Alternatively, if
an Ei411H Remote Control Switch is in the system the Alarm can be tested by pressing the Test switch.
This is equivalent to pressing the Test button on the Alarm. For further information see "ACCESSORIES"
section.
5.2.4. 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.
