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.

CAUTION

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.
