INSTALLATION

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

The detector is plug-in type photoelectronic smoke and

heat sensors with addressable analog communications.

The sensors transmit an analog representation of smoke

density or temperature over a communication line to a

control panel. Inside MCU’s EEPROM keep the sensor’s

address that can be set by a portable Address setting

device.

Two LEDs on the sensor are controlled by the panel to

indicate sensor status.

The detector require compatible addressable

communications to function properly. Connect these

sensors to listed-compatible control panels only.

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 per the wiring diagram, Figure 1.

2. Set the desired address by portable address setting

device.

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.

Figure 1. Wiring diagram:

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.

TAMPER-RESISTANCE

The detectors include a tamper-resistant capability that

prevents their removal from the bracket without the use

of a tool.

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. Smoke Entry test: Aerosol Generator (Gemini 501)

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.

A.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.

B. 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 by pressing firmly on each

of the four removal tabs that hold the cover in place.

3. Vacuum the screen carefully without removing it. If

further cleaning is required continue with Step 4,

otherwise skip to Step 7.

4. Remove the chamber cover/screen assembly by

pulling it straight out.

5. Use a vacuum cleaner or compressed air to remove

dust and debris from the sensing chamber.

6. Reinstall the chamber cover/screen assembly by

sliding the edge over the sensing chamber. Turn until

it is firmly in place.

7. Replace the cover using the LEDs to align the cover

and then gently pushing it until it locks into place.

8. Reinstall the detector.

9. Test the detector as described in TESTING.

10. Reconnect disabled circuits.

11. Notify the proper authorities that the system is back

on line.
