This sensor must be installed in compliance with the control panel system
installation manual. The installation must meet the requirements of the Au-
thority Having Jurisdiction (AHJ). Sensors offer maximum performance when
installed in compliance with the National Fire Protection Association (NFPA);
see NFPA 72.

GENERAL DESCRIPTION

Models SK-Photo, SK-Photo-T and SK-Acclimate are plug-in type smoke sen-
sors that combine a photoelectric sensing chamber with addressable-analog
communications. The sensors transmit an analog representation of smoke
density over a communication line to a control panel. Rotary dial 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 RA100Z). Models SK-Acclimate and SK-Photo-T combines a photoelec-
tronic sensing chamber and 135°F (57.2°C) fixed temperature heat detector.
The SK-Acclimate also transmits an alarm signal due to heat (135°F fixed) per
UL 521.
Please refer to the operation manual for the UL listed control unit for specific
operation of the SK-Photo, SK-Photo-T and SK-Acclimate.
The SK-Photo, SK-Photo-T and SK-Acclimate require compatible addressable
communications to function properly. Connect these sensors to listed-compat-
ible 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.
When using the SK-Acclimate as a heat detector in FM3210 compliant applica-
tions, space sensors 20 feet apart. For specific information regarding sensor
spacing, placement, and special applications, refer to NFPA 72.
Duct Applications: SK-Photo and SK-Photo-T are listed for use in ducts.
NOTE: SK-PHOTO is listed for use inside SK-DUCT 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. Im-
proper 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, 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 SK-Photo, SK-Photo-T and SK-Acclimate include a tamper-resistant ca-
pability 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.
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. Test-
ing 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 mag-
net electronically simulates smoke in the sensing chamber, testing the
sensor electronics and connections to the control panel.
