Turn on AC power and check the LED's for proper operation. The green LED lights to indicate
AC power. The red LED will flash every 40-60 seconds to indicate proper operation.

OPERATION, TESTING & MAINTENANCE

OPERATION:

 The smoke alarm is operating once the power is connected and turned on (the battery

must also be installed). When products of combustion are sensed, the unit sounds a loud alarm
which continues until the air is cleared.

This alarm incorporates the internationally recognized horn signal for evacuation. During alarm
mode, the horn produces three short beeps followed by a two second pause and then repeats.

STANDBY CONDITION:

 The red LED flashes once every 40-60 seconds to indicate the unit is

properly functioning.

LOCAL ALARM CONDITION:

 The red LED flashes rapidly and the unit emits a loud, pulsating

alarm sound.

REMOTE ALARM CONDITION:

 The red LED is off and the unit emits a loud, pulsating alarm.

GREEN LED:

 The green LED is on whenever AC power is turned on.

TESTING:

 Test by pushing the test button on the smoke alarm cover until the alarm sounds, then

release. The alarm sounds if all electronic circuitry, horn and battery are working. The alarm may
continue to sound for up to 10 seconds after the button is released. If no alarm sounds, the unit may
have a defective battery or other failure. 

Test the smoke alarm weekly to assure proper operation.

NEVER use an open flame of any kind to test this unit. You might accidentally damage or set
fire to the unit or to your home. The built-in test switch accurately tests the unit's operation as
required by Underwriters Laboratories Inc. (UL).

If you choose to use an aerosol smoke product to test the smoke alarm, be certain to use one
that has been Listed to Underwriters Laboratories, Inc. Safety Standards and use it only as
directed. Use of non-UL Listed products or improper use of UL Listed products may affect
the smoke alarm's sensitivity.

FALSE ALARMS "SILENCE" CONTROL: 

Units with the "silence" feature have the capability of

temporarily reducing the sensitivity of the alarm circuit for approximately 3-5 minutes. This feature is
to be used only when a known alarm condition such as smoke from cooking activates the smoke
alarm. The smoke alarm "silence" feature is activated by pushing the Hold to Silence button on the
smoke alarm cover for at least three seconds. The smoke alarm will automatically reduce sensitivity
and the red LED will light for approximately 3-5 minutes to indicate the alarm is in the temporary
silent condition. The smoke alarm will gradually regain normal sensitivity and sound the alarm if
particles of combustion are still present. The "silence" feature may be used repeatedly until the air
has cleared.

Before using the alarm "silence" feature, identify the source of smoke and be certain that
safe conditions exist.

MAINTENANCE:

 The smoke alarm is virtually maintenance free. However, under dusty conditions,

a vacuum hose may be used to clear the sensing chamber of dust.

Clean the smoke alarm at least once a month

 to remove dust, dirt or debris. Always turn off power

to smoke alarm before cleaning. Using a soft brush or wand attachment to a vacuum cleaner, vacuum
all sides and cover of smoke alarm. Be sure all the vents are free of debris.

If the smoke alarm is false alarming and cannot be restored to normal operation, the smoke alarm
should be replaced.
