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) as shown in the wiring
diagram. (See 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.
CAUTION
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
Intelligent photoelectric smoke 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.

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 SD365 and SD365-IV 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 com-
munication line to a control panel. Rotary dial switches are provided for set-
ting the sensor’s address. (See Figure 1.)

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).
Fire-Lite panels offer different features sets across different models. As a
result, certain features of the photoelectric sensors may be available on some
control panels, but not on others. SD365 will support only LiteSpeed® protocol
mode. SD365-IV will support either LiteSpeed or CLIP (Classic Loop Interface
Protocol) mode. 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 specific
operation. The photoelectric sensors require compatible addressable com-
munications to function properly. Connect these sensors to listed-compatible
control panels only.
SPACING
Fire-Lite recommends spacing sensors in compliance with NFPA 72. In low air
flow applications with smooth ceilings, space sensors 30 feet apart (9.1 m).
For specific information regarding sensor spacing, placement, and special ap-
plications, refer to NFPA 72 or the System Smoke Detector Application Guide,
available from Fire-Lite.
Duct Applications:
SD365 and SD365-IV are listed for use in ducts. See Duct
Smoke Detectors Applications Guide HVAG53 for details on pendant mount ap-
plications.
NOTE:
Intelligent photoelectric smoke sensors are also listed for use
inside DNR(W) duct smoke detectors.
