BEfORE INSTALLINg

This sensor must be installed in compliance with the control panel sys-
tem installation manual. The installation must meet the requirements of the
Authority Having Jurisdiction (AHJ). Sensors offer maximum performance
when installed in compliance with CAN/ULC-S524.

gENERAL DESCRIPTION

Model 2251A-COPTIR is a plug-in type smoke sensor that is a photoelec-
tronic sensing chamber combined with carbon monoxide (CO), thermal,
infra-red (IR) sensors and addressable-analog communications. The sen-
sors transmit an analog representation of smoke density over a commu-
nication 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 an-
nunciator (P/N RA100ZA /RA400ZA).
The 2251A-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 CAN/
ULC-S524. In low air flow applications with smooth ceilings, space sensors
30 feet apart. For specific information regarding sensor spacing, place-
ment, and special applications, refer to CAN/ULC-S524 or the System
Smoke Detector Application Guide, available from System Sensor.

TAMPER-RESISTANCE

Models 2251A-COPTIR includes a tamper-resistant capability that pre-
vents 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 Canadian Electrical
Code, applicable local codes, and any special requirements of the Author-
ity Having Jurisdiction. Proper wire gauges should be used. The installa-
tion wires should be color-coded to limit wiring mistakes and ease system
troubleshooting. Improper connections will prevent a system from respond-
ing properly in the event of a fire.
Remove power from the communication line before installing sen-
sors.
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 man-
ual.
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 CAN/
ULC-S536.
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, test-
ing 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 sen-
sor status. Coded signals, transmitted from the panel, can cause the
LEDs to blink, latch on, or latch off. Refer to the control panel tech-
nical documentation for sensor LED status operation and expected
delay to alarm.
B. Smoke Entry: Aerosol generator (gemini 501) or Canned Aero-
sol
The GEMINI model 501 aerosol generator can be used for smoke
entry testing. Set the generator to represent 4%/ft to 5%/ft obscura-
tion 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 Tes-
ter model 25S available from Home Safeguard Industries available
from SDi. When used properly, the canned smoke agent will cause
the smoke detector to go into alarm. Refer to the manufacturer's pub-
lished instructions for proper use of the canned smoke agent.
