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.

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.
GENERAL DESCRIPTION
Models IDP-Photo, IDP-Photo-T and IDP-Acclimate
are plug-in type smoke sensors that combine a
photoelectronic sensing chamber with addressableanalog 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
K200-04-00 1 I56-2720-00R
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.

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.

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 IDPAcclimate 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.
