OPERATION, TESTING & MAINTENANCE
OPERATION: The smoke alarm is operating once the AC power is connected and turned on (the
battery must also be installed). 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 seconds to indicate the
alarm is properly functioning.
LOCAL ORIGINATING ALARM CONDITION: The red LED blinks on approx. every 2 seconds and the
alarm emits a loud, pulsating alarm sound.
NON-ORIGINATING ALARM CONDITION: The red LED is off and the alarm emits a loud, pulsating
alarm.
GREEN LED: The green LED is on whenever AC power is turned on.
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 on Page 7.
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. If no alarm sounds,
the alarm may have a power supply failure. Test the smoke alarm weekly to assure proper operation.
ALARM ORIGINATION: The QUICK FIND
®
Alarm Origination Feature allows the user to identify the
initiating alarm smoke alarms in an interconnected alarm system. If an interconnected alarm system is
initiated by one of the alarms, when the alarm system exits alarm condition, the user can identify the
initiating alarm by:
a. Pressing and releasing the test button on any alarm in the system.
b. Interconnected alarms will sound and then stop.
c. The originating smoke alarm will continue to sound approx. 60 seconds to allow ample time to
quickly find originating alarm.

The yellow wire is used only for multiple station operations with USI ELECTRIC or UNIVERSAL
Model alarms only. Connecting this yellow wire to any other circuits may result in damage
and alarm malfunction. When alarms are interconnected, all alarms must be powered from a
single AC branch circuit. If local codes do not permit, be sure the neutral wire is common to
both phases. The maximum wire run distance between the first and last alarm/device in an
interconnected system is 1,000 feet. NOTE: Use standard household wire (18 gauge or larger,
rated at least 300V, as required by local codes) available at all electrical supply/hardware
stores.
The wiring to be used shall be in accordance with the provisions of Articles 210 and 300.3(B)
of the National Electrical Code, ANSI/NFPA 70. In addition, the resistance of the interconnecting
wiring shall be a maximum of 10 Ohms.
2. Attach the mounting bracket to the electrical junction box.
3. To activate 9 volt battery and alarm, hold the QUICK DRAW
(R)
battery drawer closed, pull and
remove the PULL-TAB. Confirm that the entire PULL-TAB has been completely removed. Discard
PULL-TAB.
4. Plug the AC QUICK CONNECTOR into the alarm base. Push and twist the alarm clockwise
onto the mounting bracket.
5. See "OPTIONAL TAMPER RESISTANT FEATURES" and "TO ACTIVATE THE LOCKING
FEATURES" instructions on Page 4.
6. Turn on AC power and check the LED's for proper operation. The green LED should be on to
indicate AC power. The red LED blinks on once approx. every 40 seconds to indicate proper
operation.
