SMOKE ALARM FEATURES

• Features False Alarm Control which, when activated, quiets unwant-

ed alarms for up to 15 minutes.

• This smoke alarm is powered by 120V AC and a 9-volt battery

back-up source. AC/DC smoke alarms offer added protection in the
event of a power failure or a drained battery.

• Unique power connector prevents interconnection with incompatible

smoke alarms or security systems.

• This smoke alarm may be interconnected with as many as 11 other

Firex model AD, ADC and PAD smoke alarms, or as many as 6
Firex model ADH heat alarms for a total of not more than 18
interconnected devices.

• Optional tamper-resist feature can safeguard against tampering.
• Unique “battery missing” signal. The smoke alarm will not attach to

the mounting bracket if a battery is not in the battery pocket.

• Improperly connected or weak battery signal. The smoke alarm will

sound a short beep about once a minute if the battery is weak or
improperly connected. The red LED will blink 4 times per minute to
help identify the alarm with the weak battery.

• Separate green and red LEDs indicate whether the smoke alarm is

receiving AC and DC power, working under normal operation, in
alarm, or under false alarm control.

• Loud alarm horn—85 decibels at 10 feet—alerts you to an emergency.
• Test button checks smoke alarm operation.

• Latching LED - the red LED blinks 3 times per minute on the unit

that initiates the alarm.

• Ramp-up test horn that emits 2 reduced-volume beeps before

reaching the full 85db level during testing.

THIS MANUAL

Installer: Please leave this
manual with the product.

The ionization type alarms are generally more effective at detecting fast, flaming
fires which consume combustible materials rapidly and spread quickly.  Sources of
these fires may include flammable liquids or paper burning in a waste container.
The photoelectric type alarms are generally more effective at detecting slow,
smoldering fires which smolder for hours before bursting into flame.  Sources of
these fires may include cigarettes burning in couches or bedding.   However, both
types of alarms are designed to provide adequate detection of both types of fires.
If you desire the benefits of both systems, you should install smoke alarms that
combine in one alarm both photoelectric and ionization sensing technologies.
