Instruction Sheet

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.
NUISANCE ALARM SILENCE FEATURE: 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 and releasing the Silence button on the smoke alarm cover while in alarm
condition. The smoke alarm will automatically reduce sensitivity and the red LED will blink on approx.
every 10 seconds to indicate the alarm is in the Silence mode. The smoke alarm will gradually regain
normal sensitivity and sound the alarm if particles of combustion are still present. The approximate 10
minute Silence feature may be used repeatedly until the air has cleared, by pushing and releasing the
Silence button again. Resetting the smoke alarm after a nuisance alarm is recommended.
NOTE: If the Test button is pressed and held during the Silence mode, the smoke alarm will be
tested normally. Upon the release of the Test button, the Silence mode will be restarted.
Before using the alarm Silence Feature, identify the source of smoke and be certain that safe
conditions exist.
(UTHA) 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, insects 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.
NEVER use an open flame of any kind to test this smoke alarm. You might accidentally damage
or set fire to the smoke alarm or to your home. The built-in test switch accurately tests the
smoke alarm's operation as required by Underwriters Laboratories Inc. (UL).
(UTHA) Sensitivity Indicating Means
The sensitivity indicating means for this Smoke and Fire Alarm is the use of the analyzer for Smoke
Detectors Model 501-A or 501-A/Bat Aerosol Generator Manufactured by Gemini Scientific Corp.,
1122-B Aster Ave., Sunnyvale, CA 94086.
The
Equivalent UL 268 Light obscuration %/Ft as measured by this instrument must be within the
obscuration listed on the back of this alarm.
(UTHA) Go/No-Go Field Test
The Go/No-Go test for this smoke and fire alarm is to use one of the following UL listed can-type aerosol
smoke alarm testers. The instructions for use are printed on the canister. Home Safeguard, Model 25S.
NOTE: It is best to "reset" the alarms before initial test is performed. See Page 7 for Reset procedures.
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.
RESET: To reset the QUICK FIND
®
Alarm Origination condition, press and hold the Test button
on any alarm for at least 10 seconds and then release. Reset after each alarm. The reset
feature will reset all interconnected units.
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 green LED stays on. The alarm should be replaced immediately.
The product end-of-service life signal can be silenced for approximately 4 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 9 hours. The
end-of-service life signal will reactivate after the silence period.
