TROUBLESHOOTING
ALARM SOUNDS FOR NO APPARENT REASON:
(1) Identify the alarm source. On all interconnected units, the
red light under the test button or on the cover will flash
rapidily only on the unit which is the source of the alarm.
(2) Check for fumes, steam etc. from the kitchen or bathroom.
Paint and other fumes can cause nuisance alarms.
(3) Fan the unit vigorously with a newspaper to disperse
fumes.
(4) If alarm does not stop, disconnect the 12V supply.
INTERCONNECTED ALARM DO NOT ALL SOUND:
(1) Hold test button for 10 seconds after first alarm has
sounded to ensure signal is transmitted to all units.
(2) Check that cables have been correctly connected and that
the connections are tight.
