CAUTION
Canned aerosol simulated smoke (canned smoke agent) formulas will vary
by manufacturer. Misuse or overuse of these products may have long term
adverse effects on the smoke detector. Consult the canned smoke agent
manufacturer’s published instructions for any further warnings or caution
statements.
For 2251A-COPTIR, smoke entry testing should be performed im-
mediately following the magnet test. Magnet test initiates an ap-
proximately 10 minute period when the detector’s signal processing
software routines are not active. Failure to first perform the magnet
test will introduce a time delay before the detector alarms.
C. Multi-Criteria Method
The Testifire® model 2001 Multi-Stimulus Detector Tester by SDi/No
Climb Products, Ltd can be used to test the 2251A-COPTIR in multi-
criteria mode. This tester is capable of introducing smoke, heat and
carbon monoxide either sequentially or simultaneously. Follow the
manufacturer’s recommendations for proper testing and operation of
the Testifire unit.
D. Direct heat Method (hair Dryer of 1000-1500 watts)
A hair dryer of 1000-1500 watts should be used to test the thermistors.
Direct the heat toward either of the two thermistors, holding the heat
source approximately 12 inches from the detector in order to avoid dam-
aging the plastic housing. The detector will reset only after it has had
sufficient time to cool. Make sure both thermistors are tested individu-
ally.
A sensor that fails any of these tests should be cleaned as described un-
der CLEANING, and retested. If the sensor fails after cleaning, it must be
replaced.When testing is complete, restore the system to normal operation
and notify the proper authorities that the system is back in operation.
CLEANINg
Before removing the detector, notify the proper authorities that the smoke
detector system is undergoing maintenance and will be temporarily out of
service. Disable the zone or system undergoing maintenance to prevent
unwanted alarms.
1. Remove the sensor to be cleaned from the system.
2. Remove the sensor cover. Use a small flat blade screwdriver to gently
release each of the four cover removal tabs that hold the cover place.
Use caution to avoid damaging the thermistors and other sensors
3. Carefully vacuum the outside of the anti insect screen without remov-
ing it from the detector cover.
4. The chamber cover, CO and IR sensors may be removed as a single
assembly. Gently pull the assembly away from the sensing chamber
being careful neither to damage the thermistors, the IR / CO sensor
PCB nor to strain the connector cable to the PCB, then gently folded
away from the optical chamber.
5. Use a vacuum cleaner and/or clean compressed air to remove dust
and debris from the sensing chamber and sensing chamber cover.
6. Re-install the sensing chamber cover assembly by sliding the cover
over the chamber, gently pressing it home until it snaps into place.
7. Re-install the sensor cover. Use the cover removal tabs, LEDs and
thermistors to align the cover with the sensor. Snap the cover into
place.
8. When all sensors have been cleaned and re-installed, restore power
to the loop and test the sensor(s) as described under TESTING.
After completion of maintenance and testing, notify the proper authorities
that the system is operational.
CO SENSOR LIfETIME
The CO cell has an expected lifetime of approximately six years. The de-
tector is programmed to signal the approach of end of this lifetime to the
control panel. The CO cell is not a field replaceable component and on
failure, you should contact the system supplier to arrange for replacement
of the cell or the detector itself.
System Sensor warrants its enclosed smoke detector to be free from defects 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 workman-
ship under normal use and service during the three year period commencing 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
