BEFORE INSTALLING

This sensor must be installed in compliance with the control panel system
installation manual. The installation must meet the requirements of the
Authority Having Jurisdiction (AHJ). Sensors offer maximum performance
when installed in compliance with the National Fire Protection Association
(NFPA); see NFPA 72.

GENERAL DESCRIPTION

Model 2251-COPTIR is a plug-in type smoke sensor that is a photoelectronic
sensing chamber combined with carbon monoxide (CO), thermal, infra-red
(IR) sensors and addressable-analog communications. The sensors transmit
an analog representation of smoke density over a communication line to a
control panel. Rotary-decade switches are provided for setting the sensor’s
address.

Two LEDs on the sensor are controlled by the panel to indicate sensor sta­tus. An output is provided for connection to an optional remote LED an­nunciator (P/N RA100Z /RA400Z).

The 2251-COPTIR requires compatible addressable communications to
function properly. Connect these sensors to listed-compatible control pan­els only.

SPACING

System Sensor recommends spacing sensors in compliance with NFPA 72.
In low air flow applications with smooth ceilings, space sensors 30 feet
apart. For specific information regarding sensor spacing, placement, and
special applications, refer to NFPA 72 or the System Smoke Detector Applica-
tion Guide, available from System Sensor.

TAMPER-RESISTANCE

Models 2251-COPTIR includes a tamper-resistant capability that prevents
removal from the bracket without the use of a tool. Refer to the base man­ual for details on making use of this capability.

WIRING GUIDE

All wiring must be installed in compliance with the National Electrical
Code, applicable local codes, and any special requirements of the Authority
Having Jurisdiction. Proper wire gauges should be used. The installation
wires should be color-coded to limit wiring mistakes and ease system trou­bleshooting. Improper connections will prevent a system from responding
properly in the event of a fire.

Remove power from the communication line before installing sensors.

1. Wire the sensor base (supplied separately) per the wiring diagram, see
Figure 1.

2. Set the desired address on the sensor address switches, see Figure 2.

3. Install the sensor into the sensor base. Push the sensor into the base
while turning it clockwise to secure it in place.

4. After all sensors have been installed, apply power to the control unit
and activate the communication line.

5. Test the sensor(s) as described in the TESTING section of this manual.

Dust covers provide limited protection against airborne dust particles dur­ing shipping. Dust covers must be removed before the sensors can sense
smoke. Remove sensors prior to heavy remodeling or construction.

TESTING

Before testing, notify the proper authorities that the system is undergoing
maintenance, and will temporarily be out of service. Disable the system to
prevent unwanted alarms.

All sensors must be tested after installation and periodically thereafter. Testing
methods must satisfy the Authority Having Jurisdiction (AHJ). Sensors offer
maximum performance when tested and maintained in compliance with NFPA

72.

The sensor can be tested in the following ways:

A. Functional: Magnet Test (P/N M02-04-01 or M02-09-00)

This sensor can be functionally tested with a test magnet. The test

magnet electronically simulates smoke in the sensing chamber, testing
the sensor electronics and connections to the control panel.

1. Hold the test magnet in the magnet test area as shown in Figure 3.

2. The sensor should alarm the panel.

Two LEDs on the sensor are controlled by the panel to indicate sensor

status. Coded signals, transmitted from the panel, can cause the LEDs
to blink, latch on, or latch off. Refer to the control panel technical
documentation for sensor LED status operation and expected delay to
alarm.

B. Smoke Entry: Aerosol Generator (Gemini 501) or Canned Aerosol

The GEMINI model 501 aerosol generator can be used for smoke entry

testing. Set the generator to represent 4%/ft to 5%/ft obscuration as
described in the GEMINI 501 manual. Using the bowl shaped applica­tor, apply aerosol until the panel alarms.

Additionally, canned aerosol simulated smoke (canned smoke agent)

may be used for smoke entry testing of the smoke detector. Tested and
approved aerosol smoke products are the Smoke Detector Tester model
25S available from Home Safeguard Industries and Chekkit Smoke De­tector Tester models CHEK02 and CHEK06 available from SDi. When
used properly, the canned smoke agent will cause the smoke detector
to go into alarm. Refer to the manufacturer’s published instructions
for proper use of the canned smoke agent.

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 2251-COPTIR, smoke entry testing should be performed immedi-

ately following the magnet test. Magnet test initiates an approximately
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 2251-COPTIR in multi­criteria 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 dam­aging the plastic housing. The detector will reset only after it has had suf­ficient time to cool. Make sure both thermistors are tested individually.

A sensor that fails any of these tests should be cleaned as described under
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 remov­ing 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 detec­tor 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.
