This sensor must be installed in compliance with the control panel sys-
tem 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
Model SS-PHOTO-T is a plug-in type multi-sensor smoke sensor that
combines a photoelectronic sensing chamber and 135°F (57.2°C) fixed tem-
perature heat detector across addressable-analog communications. The
sensors transmit an analog representation of smoke density over a commu-
nication line to a control panel. Rotary dial switches are provided for setting
the sensor's address. (See Figure 1.) The intelligent photoelectric and tem-
perature sensors also transmit an alarm signal due to heat at 135°F (57.2°C)
per UL 521.

TENS
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).
System Sensor panels offer different feature sets across different models. As
a result, certain features of the photoelectric and temperature sensors may be
available on some control panels, but not on others. These devices support
SS, LiteSpeed, and SK protocol. The possible features available if supported
by the control panel are:
1. The sensor's LEDs can operate in three ways—on, off, and blinking–and
they can be set to red, green, or amber. This is controlled by the panel.
2. The remote output may be synchronized to the LED operation or con-
trolled independent of the LEDs.
3. Devices are point addressable up to 159 addresses.
Please refer to the operation manual for the UL listed control panel for spe-
cific operation. The photoelectric and temperature sensors require compatible
addressable communications to function properly. Connect these sensors to
listed-compatible control panels only.
SPACING
System Sensor recommends spacing sensors in compliance with NFPA 72.
In low air flow applications with smooth ceilings, space sensors 30 feet apart
(9.1 m). When using the photoelectric and temperature sensors as a heat
detector in FM3210 compliant applications, space sensors 20 feet apart (6
m). For specific information regarding sensor spacing, placement, and spe-
cial applications, refer to NFPA 72 or the System Smoke Detector Application
Guide, available from System Sensor.

WIRING GUIDE
All wiring must be installed in compliance with the National Electrical Code,
applicable local codes, and any special requirements of the Authority Hav-
ing Jurisdiction. Proper wire gauges should be used. The installation wires
should be color-coded to limit wiring mistakes and ease system troubleshoot-
ing. 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 2.
2. Set the desired address on the sensor address switches, see Figure 1.
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 panel 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
Photoelectric and temperature sensors include a tamper-resistant capability
that prevents their removal from the base 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.
