Attach the mounting bracket in the proper location on the wall or ceiling (screws and anchors provided).

To activate 9 volt battery and alarm, hold the battery, pull and remove the PULL-TAB. Confirm

that the entire PULL-TAB has been completely removed. Discard PULL-TAB.

Push and twist the alarm clockwise onto the mounting bracket.

See "OPTIONAL TAMPER RESISTANT FEATURE" and "TO ACTIVATE THE LOCKING

FEATURE" instructions on Page 4.

The red LED will blink on approx. every 40-45 seconds to indicate proper operation.

OPERATION: The smoke alarm is operating once the battery power is connected by removing the

pull-tab. When products of combustion are sensed, the alarm sounds a loud alarm which continues

until the air is cleared.

This alarm incorporates the NFPA recognized horn signal for evacuation. During alarm mode, the

horn produces three long beeps followed by a two second pause and then continually repeats.

READY/ACTIVE CONDITION: The red LED blinks on once approx. every 40-45 seconds to indicate

the alarm is properly functioning.

ALARM CONDITION: The red LED blinks on once approx. every 2 seconds and the alarm emits a

loud, pulsating alarm sound.

NUISANCE ALARMS: The smoke alarm is designed to minimize nuisance alarms. Smoking will

not normally set off the alarm unless smoke is blown directly into the smoke alarm. Combustion

particles from cooking may set off the alarm if the smoke alarm is located close to the kitchen

cooking surface. Large quantities of combustion particles are generated from spills or broiling.

If the smoke alarm does sound, check for fires first. If a fire is discovered, get out and call the fire

department. If no fire is present, check to see if one of the reasons listed above may have caused

the alarm. Use the Silence Feature if it is a nuisance alarm, or reset the alarm by pressing and

holding the test button for ten seconds. Refer to RESET below.

NOTE: It is best to "reset" the alarms before initial test is performed. See below for Reset procedures.

TESTING: Test by pressing 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. If no alarm

sounds, the alarm may have a power supply failure. Test the smoke alarm weekly to assure

proper operation. IMPORTANT: Under normal conditions, the test button should sound the alarm

immediately after it is pressed. There are special conditions that when you press the test button,

you will experience a delay of approximately 10-15 seconds before the alarm sounds. This delay

occurs if the test button is pressed during a self-diagnostic period.This occurs: (1) upon initial

power up; (2) after battery replacement (and no AC power is present) and (3) if 120 volt AC

power has been interrupted and no backup battery was present.

ALARM ORIGINATION: The QUICK FIND

alarm (once the alarm has stopped sounding). To initiate QUICK FIND

button on each alarm. After releasing the button, the originating alarm will continue to sound for 60

seconds. In a non-interconnected installation, it is necessary to test each alarm to determine the

originating alarm.

RESET: To reset the QUICK FIND

approx. 10 seconds, or temporarily remove (and then replace) the battery. This will clear

alarm origination indicator.

END-OF-SERVICE LIFE NOTIFICATION: A majority of home fire deaths are a result of no smoke

alarms or no working smoke alarms. In addition to the "replace by date" stamped on the back of your

alarm, your alarm contains a unique audible end-of-service life notification feature. When it is time

to replace your alarm, which is after approximately 10 years of operation from initial power up, the

alarm will sound 1 beep approx. every 60 seconds and the red LED will blink on once approx. every

40-45 seconds. The alarm should be replaced immediately.

The end-of-service life signal can be silenced for approximately 6 hours. To perform this function,

press and release the test button. The alarm will sound for approximately 60 seconds while it resets.

After the reset function is completed, the alarm will be silent for approximately 6 hours. The end-of-

service life signal will reactivate after the silence period.
