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

Models IDP-Photo, IDP-Photo-T and IDP-Acclimate

are plug-in type smoke sensors that combine a

photoelectronic sensing chamber with 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 status. An output is provided for

connection to an optional remote LED annunciator (P/N

RA400Z). Models IDP-Acclimate and IDP-Photo-T

combines a photoelectronic sensing chamber and 135°F

(57.2°C) fixed temperature heat detector.

Please refer to the operation manual for the UL listed

control unit for specific operation of the IDP-Photo, IDP-

Photo-T and IDP-Acclimate.

The IDP-Photo, IDP-Photo-T and IDP-Acclimate require

compatible addressable communications to function

properly. Connect these sensors to listed-compatible

control panels only.

SPACING

Silent Knight 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.

Duct Applications: IDP-Photo and IDP-Photo-T are listed

for use in ducts.

NOTE: These products are not listed for use inside duct

smoke detectors.

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 (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 during shipping. Dust covers must be

removed before the sensors can sense smoke. Remove

sensors prior to heavy remodeling or construction.

TAMPER-RESISTANCE

Models IDP-Photo, IDP-Photo-T and IDP-Acclimate

include a tamper-resistant capability that prevents their

removal from the bracket without the use of a tool. Refer to

the base manual for details on making use of this capability.

CAUTION

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

other UL lised devices)

The GEMINI model 501 aerosol generator can be

used for smoke entry testing. Other UL listed smoke

generating devices may be used as well. 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.

For IDP-Acclimate, smoke entry testing should be

performed immediately following the magnet test.

Magnet test initiates an approximately 10 minute period

when the detector’s signal processing software routines

are not active. Failure to first perform the magnet test

will introduce a time delay before the detector alarms.

C. Direct Heat Method (Hair dryer of 1000-1500

watts). IDP-Photo-T and IDP-Acclimate only.

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 and returned for repair.

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. Make sure that the thermistors do not become

bent under the cover on the IDP-Photo-T and IDP-

Acclimate models.

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.
