6. Initial Testing and Checking of Alarm
• Having energised circuit, press and hold the test button again – the alarm
should sound and other interconnected ones also, within a few seconds.
• Do this for all alarms.
• If any do not sound, isolate mains and recheck cabling.
• On optical alarms if the red L.E.D. blinks every 30-40 seconds and the alarm
chirps inbetween, it indicates failure of the sensing chamber - replace alarm.
{This condition also exists if the Hush button is pushed}
• Advise the house-holder (if present) as to how to test the alarms.
7. Interconnecting
• You may interconnect up to 23 Kidde Fyrnetics AC smoke, heat or CO alarms to
this unit. i.e. 24 in total.
• Crossing line and neutral connections or line and interconnect connections will
fatally damage all interconnected alarms invalidating the guarantee.
• All interconnected alarms must be powered off the same fuse/circuit breaker.
Total cable length between alarms must not exceed 250m (273yds) and be 1.0mm
in diameter, 3 core and earth (BS6243Y). Wiring must conform to the
