Three-Year Limited Warranty
System Sensor warrants its enclosed smoke detector to be free from de-
fects in materials and workmanship under normal use and service for a
period of three years from date of manufacture. System Sensor makes no
other express warranty for this smoke detector. No agent, representative,
dealer, or employee of the Company has the authority to increase or alter
the obligations or limitations of this Warranty. The Company’s obligation
of this Warranty shall be limited to the repair or replacement of any part of
the smoke detector which is found to be defective in materials or work-
manship under normal use and service during the three year period com-
mencing with the date of manufacture. After phoning System Sensor’s toll
free number 800-SENSOR2 (736-7672) for a Return Authorization number,
send defective units postage prepaid to: System Sensor, Repair Depart-
ment, RA #__________, 3825 Ohio Avenue, St. Charles, IL 60174. Please
include a note describing the malfunction and suspected cause of failure.
The Company shall not be obligated to repair or replace units which are
found to be defective because of damage, unreasonable use, modifica-
tions, or alterations occurring after the date of manufacture. In no case
shall the Company be liable for any consequential or incidental damages
for breach of this or any other Warranty, expressed or implied whatsoever,
even if the loss or damage is caused by the Company’s negligence or fault.
Some states do not allow the exclusion or limitation of incidental or conse-
quential damages, so the above limitation or exclusion may not apply to
you. This Warranty gives you specific legal rights, and you may also have
other rights which vary from state to state.
Connecting Auxiliary Devices with Relay
This detector has a built-in relay which may be used to activate auxiliary
devices such as bells, horns, and door closers. The relay contacts auto-
matically close approximately eight (8) seconds after the detector goes
into alarm, and automatically resets approximately five (5) seconds after
the alarm stops. For wiring refer to Figure 8. Auxiliary voltage and current
requirements must be within relay contact ratings and appropriate wiring
must be used.
How to Interconnect Detectors
NOTE: Interconnect smoke detectors within one household only. If detec-
tors are interconnected between households, nuisance alarms will
occur when a detector in another residence is tested.
•
Up to twelve 1012, 2012, and 2001LVRI detectors may be intercon-
nected so that if one detector senses smoke, all of them will sound an
alarm. After interconnecting the detectors, push the test switch on one
detector. The alarm horns on all of the other detectors should sound if
they are connected correctly.
•
Connect the detectors together by connecting all the signal terminals
to each other and all ground terminals to each other. (See Figure 7.)
Use 18 guage (#18AWG) or larger two-conductor stranded wire.
•
If detectors will not be interconnected, DO NOT use signal and
ground terminals.
•
The LEDs on all smoke detectors should flash about 1 to 2 times per
minute when power is turned on to the detectors. Test detectors after
interconnection wiring is complete.
Cautionary Note: Test interconnection wiring after installation is com-
pleted. Test each unit in a system and make sure ALL other
units alarm. FAILURE TO OBSERVE ANY OF THESE CONDI-
TIONS CAN CAUSE SYSTEM MALFUNCTION AND/OR DAM-
AGE TO THE DETECTORS.
Testing Information
•
You should test your detector at least once a week to assure yourself of
its operation, as recommended by NFPA. Test the detector by firmly de-
pressing the recessed test switch located on the detector cover (marked
“Push to Test”) with a 0.1 inch diameter tool such as an allen wrench
or small screwdriver FOR 20 SECONDS. (See Figure 9). The alarm
horn should sound, and the LED should flash rapidly.
•
In an interconnected system, all of the detectors should sound their
alarm horns when any one of the test buttons is pushed. If the alarm
horn makes a continuous loud sound, the detector is working properly.
This is the only way to be sure the detector is working. Test the de-
tector weekly. If the detector fails to test properly, have it repaired
or replaced immediately.
WARNING: Never use an open flame of any kind to test the smoke de-
tector. You may set fire to and damage the detector, as well as your home.
The built-in test switch accurately tests all detector functions, as required
by Underwriter's Laboratories.
•
DANGER: If the alarm horn sounds a loud continuous sound and
you are not testing the detector, the detector has sensed smoke or
combustion particles in the air. THE ALARM HORN IS A WARNING
OF A POSSIBLY SERIOUS SITUATION. IT REQUIRES YOUR IMME-
DIATE ATTENTION. See “What to Do In Case of Fire” section of this
manual.
•
The alarm could be caused by a nuisance situation. Cooking smoke or
a dusty furnace can cause the alarm to sound. If this happens, open a
window or fan the air to remove the smoke or dust. The alarm will
turn itself off as soon as the air is completely clear. DO NOT TURN
OFF POWER TO THE SMOKE DETECTOR. THIS WILL REMOVE
YOUR PROTECTION.
Monitoring Your Detector
Once the detector is powered, a green LED flashes about 1 to 2 times per
minute. This signals that the detector is receiving power and is in the de-
tect mode. If the detector is not operating properly, the green LED will be
OFF. (If so, have the detector repaired or replaced immediately.) When the
smoke detector senses smoke, the green LED will flash rapidly. If the initi-
ating smoke detector senses smoke and signals other interconnected
smoke detectors to sound their alarms, their LEDs will flash about 1 to 2
times per minute. See chart below for specific LED functions.

The detector will automatically return from Alarm to Normal state when
the reason for alarm, as the presence of smoke, is completely removed.
Cleaning and Maintenance
DANGER: Electrical Shock Hazard. Turn off power to the smoke detector
at the main service panel before cleaning the smoke detector.
This smoke detector has been designed to be as maintenance-free as pos-
sible. However, regular testing (see “Testing” above) and periodic mainte-
nance are necessary.
To clean the detector, turn off power and vacuum the outside of the detec-
tor with the soft brush attachment of a vacuum cleaner. Do this at least
once every year, preferably every six months. DO NOT ATTEMPT TO
CLEAN THE DETECTOR IN ANY OTHER WAY.
If the detector requires service, do not attempt to service it yourself; this
will void your warranty. Send the detector to: Repair Department, System
Sensor, 3825 Ohio Avenue, St. Charles, Illinois 60174. Enclose a note de-
scribing what is wrong with the detector.
