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 7351J is a plug-in type smoke sensor that uses a laser based photoelectronic sensing chamber. The sensor uses analog-addressable communications
to transmit smoke density and other information to the control panel.
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).
Johnson Controls panels offer different features sets across different models. As a result, certain features of the product may be available on some control
panels, but not on others. The possible features available in the product, if supported by the control unit are:
1. The panel controls the LED operation on the sensor. Operational modes are RED blink, RED continuous, GREEN blink, and off.
2. The remote output may be synchronized to the LED operation or controlled independent of the LEDs.
Please refer to the operation manual for the UL listed control unit for specific operation of the 7351J.

SPACING
Johnson Controls recommends spacing sensors in compliance with NFPA 72. In low air flow applica-
tions with smooth ceilings, space sensors 30 feet apart. For specific information regarding sensor
spacing, placement, and special applications, refer to NFPA 72 or Johnson Controls

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 trouble-
shooting. 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 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 commu-
nication 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.
