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 SK-Photo, SK-Photo-T and SK-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/RA100Z). Models SK-Acclimate and SK-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 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-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: SK-Photo and SK-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, 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 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.
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 mag-
net 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.Additionally, canned aerosol simulated smoke
(canned smoke agent) may be used for smoke entry testing of the smoke
detector. Tested and approved aerosol smoke products are the Smoke Detector Tester model 25S available from Home Safeguard Industries and
Chekkit Smoke Detector Tester models CHEK02 and CHEK06 available
from SDi. When used properly, the canned smoke agent will cause the
smoke detector to go into alarm. Refer to the manufacturer’s published
instructions for proper use of the canned smoke agent.
Canned aerosol simulated smoke (canned smoke agent) formulas will vary by
manufacturer. Misuse or overuse of 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.
For SK-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). SK-Photo-T and
SK-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.
FIGURE 3:
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 SK-Photo-T and SK-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.
