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 sta-
tus. An output is provided for connection to an optional remote LED an-
nunciator (P/N RA100Z /RA400Z).
The 2251-COPTIR requires compatible addressable communications to
function properly. Connect these sensors to listed-compatible control pan-
els 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 man-
ual 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 trou-
bleshooting. 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 dur-
ing 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 applica-
tor, 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 De-
tector 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.
