SD350 and SD350T Addressable Photoelectronic Smoke Sensors
Installation and Maintenance Instructions
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
Model SD350 and SD350T are addressable sensors that combine a state-of-the-art photoelectronic sensing chamber with communications. The SD350T
adds thermal sensors that will alarm at a fixed temperature of 135
°
F. These sensors are designed to provide open area protection and are intended for use
with compatible control panels only.
Two LEDs on each sensor light to provide a local, visible sensor indication. Remote LED annunciator capability is available as an optional accessory (Part
No. RA400Z).

SPACING
Fire•Lite 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 or
the Guide For Proper Use of System Smoke Detectors, available from
Fire•Lite (P/N I56-407-XX).
WIRING INSTRUCTIONS
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.
Disconnect power from the communication line before installing sensors.
All wiring must conform to applicable local codes, ordinances, and regulations.
1. Wire the sensor base (supplied separately) per the wiring diagram (Figure 1).
2. Set the desired address on the sensor address switches.
NOTE: Some panels support extended addressing. In order to set the sensor above address 99
on compatible systems, carefully remove the stop on the upper rotary switch with thumb or as shown in 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.
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 magnet 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.
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 con-
trol panel technical documentation for sensor LED operation and expected delay to alarm.

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.
