LED INDICATORS: This smoke alarm is equipped with red and green LED indica-
tors. The green LED (when illuminated) indicates the presence of AC power.
The red LED has four modes of operation:
Standby Condition:
The red LED will flash every 40 seconds to indicate
that the smoke alarm is operating properly.
Alarm Condition:
When the alarm senses products of combustion and
goes into alarm, the red LED will flash one flash per
second. The flashing LED and pulsating alarm will
continue until the air is cleared.
WHEN UNITS ARE INTERCONNECTED, only the red LED
of the alarm which senses the smoke or is being tested
(the originating unit) will flash. All other units in the
interconnect system will sound an alarm but their red
LED’s will NOT be flashing.
Alarm Memory:
This smoke alarm is equipped with an alarm memory,
which provides a visual indication when an alarm has
been activated. The red LED will illuminate for about 1.5
seconds every 20 seconds to indicate the memory
condition. The memory will remain activated until
pushing the Test/Hush Button resets it or will time-out
between 11 to 13 hours. In an interconnected installation
only the memory of the originating alarm will be activated.
Hush
®
mode:
The red LED will illuminate for 1.5 seconds every 10
seconds, indicating the smoke alarm is in the Hush®
mode.
TESTING: Test by pushing the Test/Hush button on the cover and hold it down
for a minimum of 5 seconds. This will sound the alarm if all the electronic cir-
cuitry, horn and battery are working. In an interconnected installation all inter-
connected alarms should sound when the test feature on any one of the inter-
connected alarms is activated. If no alarm sounds, check the fuse or circuit
breaker supplying power to the alarm circuit. If the alarm still does not sound,
the unit has defective batteries or other failure. DO NOT use an open flame to
test your alarm, you could damage the alarm or ignite combustible materials
and start a structure fire.
TEST THE ALARM WEEKLY TO ENSURE PROPER OPERATION. Erratic or low sound
coming from your alarm may indicate a defective alarm, and it should be
returned for service (see Section 12).
