BEFORE INSTALLING

Please thoroughly read the System Sensor manual A05-1003, Applications

Guide for System Smoke Detectors, which provides detailed information on

detector spacing, placement, zoning, wiring, and special applications. Copies

of this manual are available from System Sensor.

NOTICE: This manual should be left with the owner/user of this equipment.

IMPORTANT: The detector must be tested and maintained regularly following

NFPA 72 requirements. The detector should be cleaned at least once a year.

GENERAL DESCRIPTION

The 2D51 photoelectronic detector uses a state-of-the-art optical sensing

chamber. This detector is designed to provide protection in duct applications

when installed with an Innovair Flex 4-wire duct smoke detector housing and

to be used with compatible UL listed control panels only.

The 2D51 can also be used in pendant mount applications when installed with

a B210LP or B501 base and D4P120 power board components.

Two LEDs on each detector provide local visible alarm indication. They flash

every five seconds indicating that power is applied and the detector is working

properly. The LEDs latch on in alarm. LEDs will be off when a trouble condi-

tion exists indicating that the detector sensitivity is outside the listed limit.

See applicable Innovair Flex duct smoke detector installation manual for more

information.. The alarm can be reset by a momentary power interruption,

test/reset button, or remote test accessory with reset function. This detector

may be tested by activating the internal reed switch with a magnet, test/reset

button, or remote test accessory.

INSTALLATION

NOTE: All wiring must conform to applicable local codes, ordinances, and

regulations.

WARNING

Remove power from initiating-device circuits before installing detectors.

1. Install detectors:

a. Place the detector into the detector base.

b. Turn the detector clockwise until the detector drops into place.

c. Continue turning detector clockwise to lock it in place.

2. After all detectors have been installed, apply power to the control unit.

3. Test the detector using the test/reset button or magnet as described

under TESTING

4. Reset the detector at the system control panel or on power board.

5. Notify the proper authorities that the system is back on line.

CAUTION

Dust covers are an effective way to limit the entry of dust into smoke detector sens-

ing chambers. However, they may not completely prevent airborne dust particles

from entering the detector. Therefore, System Sensor recommends the removal

of detectors before beginning construction or other dust producing activity.

Be sure to remove the dust covers from any sensors that were left in place dur-

ing construction as part of returning the system to service.

TESTING

Before testing, notify the proper authorities that the smoke detector system

is undergoing maintenance and will temporarily be out of service. Detectors

must be tested after installation and as part of periodic maintenance. Test the

2D51 as follows:

SPECIFICATIONS

Height: 2.0 in

Diameter: 4.1 in; 6.1 in

Weight: 3.1 oz. (88 g)

Operating Temperature Range: –20°C to 70°C (–4°F to 158°F)

Operating Humidity Range: 0% to 95% Relative Humidity Non-condensing

NOTE: Before testing the detector, check to ensure the the power board LEDs

blink. If they do not, the detector may not have power or may not be installed

properly (check the wiring), if it is defective, or the detector sensitivity is out-

side the listed limits return it for repair.

ALARM TESTS

1a. Test/Reset Button - Press and hold the test button located on the power

board cover for at least 2 seconds.

1b. M02-04-00 Magnet Test - Place the painted surface of the magnet onto

the MAGNET TEST location on the sensor cover or the duct smoke

detector (Figure 1).

2. The red alarm LED on the sensor and the power board should latch on,

as should any accessories (i.e. RA100Z, RTS151). Verify system control

panel alarm status and control panel execution of all intended auxiliary

functions (i.e fan shutdown, damper control, etc.).

3. The detector must be reset by the system control panel, front cover Test/

Reset button, or remote accessory.

4. To reset using the Test/Reset button on the power board cover simply

press and release.

SMOKE RESPONSE TESTS

To determine if smoke is capable of entering the sensing chamber, visually

identify any obstructions. Plug the exhaust and sampling tube holes to pre-

vent ducted air from carrying smoke away from the detector head, then blow

smoke such as cigarette, cotton wick, or punk directly at the head to cause

an alarm. REMEMBER TO REMOVE THE PLUGS AFTER THIS TEST, OR THE

DETECTOR WILL NOT FUNCTION PROPERLY.

SMOKE ENTRY USING AEROSOL SMOKE

This test is intended for low-flow systems (100-500 FPM). If the air speed is

greater than 500 FPM, use a conventional manometer to measure differential

pressure between the sampling tubes, as described per the installation manual

provided with the duct smoke detector.

Drill a

⁄4 inch hole 3 feet upstream from the duct smoke detector. With the air

handler on, measure the air velocity with an anemometer. Air speed must be

at least 100 FPM. Spray aerosol smoke* into the duct through the

⁄4 inch hole

for five seconds. Wait two minutes for the duct smoke detector to alarm. If the

duct smoke detector alarms, air is flowing through the detector. Remove the

duct smoke detector cover and blow out the residual aerosol smoke from the

chamber and reset the duct smoke detector. Use duct tape to seal the aerosol

smoke entry hole.

*Aerosol smoke can be purchased from Home Safeguard Industries at home-

safeguard.com, model 25S Smoke Detector Tester, and Chekkit Smoke Detector

Tester model CHEK02 and CHEK06 available from SDi. When used properly,

the canned smoke agent will cause the smoke detector to go into alarm. Re-

fer 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 to 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.
