User Manual
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 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.
NEVER use an open ame of any kind to test this smoke alarm. You might accidentally
damage or set re 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 Scientic 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 re 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.
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 res rst. If a re is discovered, get out and call the re
department. If no re 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.
NOTE: It is best to "reset" the alarms before initial test is performed. See RESET procedures below.
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: Patented Quick Find® Alarm Origination—In an interconnected system
consisting of any of these models: MI106S, MIC1509S, 5304, MI106, MDS107, MCN108, MICN109,
MDSCN111, MP117, it may be difcult to determine which alarm initiated the alarms to sound during
an alarm event. This Quick Find® feature will immediately allow you to locate the originating alarm
once the alarms have stopped sounding. To initiate Quick Find®, press and hold the test/silence
button on any alarm until the test sequence on this alarm begins. Release the test button. The
specic horn pattern/sequence is designated by the alarm type. Once this test sequence ends,
the originating alarm continues to sound for approximately 60 seconds, which provides ample
time to locate the originating alarm. Remember to reset the originating alarm in order to clear the
Quick Find® alarm origination, and to return your system to normal operation. Refer to the wiring
instructions/model interconnect compatibility section of this manual for additional information. In
a non-interconnected installation, it is necessary to test each alarm by pressing the test/silence
button to determine the 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.
