After installation, TEST your alarm by pressing and holding the test button for
several seconds. This should sound the alarm.
4. OPERATION AND TESTING
OPERATION: The smoke alarm is operating once A.C. power is applied, fresh
batteries are installed and testing is complete. When the smoke alarm ionization
chamber senses products of combustion, the horn will sound a loud (85db) tem-
poral alarm until the sensing chamber is cleared of smoke particles.
LED INDICATORS: This smoke alarm is equipped with red and green LED indica-
tors. The green LED is located under test button "B" and will be illuminated
when AC power is present. The red LED is located under test button “A”.
Standby:
The red LED will flash briefly approximately every 30- 40 seconds to
indicate that smoke alarm is operating properly.
Alarm
When the unit senses products of combustion and goes into alarm,
mode:
the red LED will flash rapidly (one flash per second). The rapid
flashing LED and temporal 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 rapidly. All
other units in the interconnect system will sound an alarm but their red LED's
will NOT flash rapidly.
Sensitivity
The red LED will be on while Test "B" button is being pressed.

Alarm
This smoke alarm is equipped with an alarm memory, which
Memory:
provides a visual indication when an alarm has been activated.
The red LED will illuminate for about 1.5 seconds every 16 seconds
to indicate the memory condition. The memory will remain activated
until pushing the test button resets it. The memory will also reset if
the battery voltage drops to 8 volts.
In an interconnected installation only the memory of the originating alarm will
be activated.
