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 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 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. 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 approx. 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); (3) If 120 volt AC power has been interrupted

and no backup battery is present.

RV INSTALLATION

WARNING: TEST SMOKE ALARM OPERATION AFTER VEHICLE HAS BEEN IN STORAGE,

BEFORE EACH TRIP AND AT LEAST ONCE PER WEEK DURING USE. An identical marking is to

be provided by the recreational vehicle manufacturer that shall be permanent and located visibly,

within 24 inches (810mm) of the smoke alarm.

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. It is necessary to test each alarm to determine the originating alarm in a 9 volt non-

interconnected installation.

RESET: To reset the QUICK FIND

on any alarm for at least 10 seconds and then release, or temporarily remove (and then

replace) the battery. This will clear alarm origination indicator. Reset after each alarm activation.

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.
