Turn on AC power and press the TEST/RESET button. Check the LED's for proper operation
(see "TESTING YOUR ALARM"). After test sequence, the Green LED lights to indicate AC
power and blinks off approximately every 20 seconds to indicate proper operation.

OPERATION, TESTING & MAINTENANCE

OPERATION: The alarm is operating once the power is connected and turned on (the battery must
also be installed).

SMOKE/COMBUSTION PRODUCTS ALARM CONDITION:  When products of combustion are
sensed, the unit sounds a loud SMOKE alarm pattern which continues until the air is cleared. For
the SMOKE alarm pattern, this alarm incorporates the internationally recognized horn signal for
evacuation. During smoke alarm mode, the horn produces three beeps followed by a two second
pause and then repeats.

CARBON MONOXIDE CONDITION: When CO is sensed at a high level or at a low level for a
lengthy period of time, the unit sounds a loud CO alarm pattern (4 short horn pulse, pause, repeat)
which continues until the air is cleared or the alarm is reset. The Red LED will flash on simultaneously
with the horn pulses.

SERVICE/TROUBLE CONDITION: Periodically, the alarm's circuitry is tested. If an error is detected,
the alarm will sound a double "beep" and the Yellow LED will flash on twice approximately every 40
seconds. If this occurs, reset your alarm (see "RESETTING YOUR ALARM"). If the SERVICE/
TROUBLE signal persists, it is an indication of circuit malfunction and that the alarm requires
immediate servicing.

TESTING YOUR ALARM: Test alarm weekly for proper operation by pushing, then releasing, the

TEST/SILENCE button. The alarm will then test itself for proper operation of BOTH the SMOKE and

CO detection and alarm circuits. The Red LED will begin to flash rapidly and the alarm will indicate

two cycles of the SMOKE alarm pattern. The Red LED will stop flashing during the second SMOKE

alarm pattern. This will be followed by two cycles of the CO alarm pattern, during which the Green

LED is off, the Yellow LED is on and the Red LED flashes on 

simultaneously with the horn pulses.

RESETTING YOUR ALARM: To reset your alarm, initiate the Test cycle per TESTING YOUR ALARM

above. While the alarm is indicating the CO alarm patterns of the Test Cycle, press the TEST/

SILENCE button again and HOLD it until the Test Cycle is completed (when the Yellow LED turns

off, approximately 5 seconds).

STANDBY (NON-ALARM) CONDITION: Whenever AC power is present, the Green LED is on and

blinks off approximately every 20 seconds and the Red LED is off and flashes on every 40 seconds.

If powered by the backup battery (DC) only, both the Green and the Red LED's are off and flash on

every 40 seconds.

LOCAL (ORIGINATING ALARM) CONDITION: For BOTH the SMOKE and CO alarm conditions,

the Red LED flashes on rapidly and the unit emits a loud, pulsating alarm (refer to the OPERATION

section to differentiate between the SMOKE and CO alarm patterns).

REMOTE  (NON-ORIGINATING  ALARM)  CONDITION:  For  BOTH  the  SMOKE  and  CO  alarm

conditions, the Red LED is off and the unit emits a loud, pulsating alarm (refer to the OPERATION

section to differentiate between the SMOKE and CO patterns).

INITIATING ALARM INDICATOR (IAI) CONDITION: Whenever a unit comes out of the LOCAL

ALARM CONDITION, it will display an IAI until  manually reset (see "RESETTING YOUR ALARM").

If the unit indicated a SMOKE alarm, the IAI is the Red LED flashing on for 1 second every 5

seconds. If the unit indicated a CO alarm, the IAI is the Green LED which flashes on for 1 second,

then off for 1 second and then repeats this cycle until it is manually reset (see "RESETTING YOUR

ALARM").
