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

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.
