Introduction
This document contains important information about installing and
operating the Johnson Controls 5551RJ intelligent, analog, rate-of-rise
thermal detector with a conventional fixed temperature heat detector. If
you install 5551RJ intelligent rate-of-rise thermal detectors for someone
else to use, you must leave a copy of this document with the user.
Before you install the 5551RJ detector, read and become familiar with:
●the control panel system installation manual
●the requirements of the authority having jurisdiction
●National Fire Protection Association (NFPA)-72-National Fire
Alarm Code
●System Sensor Guide for Proper Use of System Smoke Detectors
Technical Bulletin in the Fire Initiating Devices and Notification
Appliances Technical Manual (FAN 408), which provides detailed
information on detector spacing, placement, zoning, wiring, and
special applications
●or, for non-United States installations, applicable codes and standards
specific to country and locality of installation
Failure to follow these directions may result in failure of the device to
report an alarm or trouble condition. Johnson Controls is not responsible
for devices that have been improperly installed, tested, or maintained by
others.
As is the case with all installations under NFPA, Underwriters
Laboratories, Inc. (UL), Underwriters Laboratories of Canada (ULC), or
Canadian Electrical Code classification, final written approval of
permissible operation and configuration rests with the authority having
jurisdiction.
4 Intelligent Products—5551RJ Intelligent Rate-of-Rise Thermal Detector w/ Fixed Temp. Heat Detector
Model 5551RJ intelligent thermal detectors utilize a state-of-the-art dual
thermistor sensing circuit for fast response. The detector transmits an
analog representation of the smoke density over a communication
Signaling Line Circuit (SLC) to the fire alarm control panel. These
detectors are designed to provide open area protection with 50 foot
spacing capability, and are designed to be used with compatible control
panels only.
!
CAUTION: Equipment hazard. Do not use in potentially
explosive atmospheres. Do not leave unused
wires exposed.
Rotary decade switches are provided on the back of the detector for setting
the detector’s SLC address.
The detector has two Light Emitting Diodes (LEDs) that provide visual
indication of the detector’s status. In normal mode, the LEDs blink every
time the detector is polled by the control panel when the blink feature is
enabled in the system programming of the control panel. When the
detector is in alarm, the LEDs are latched into a constant On condition.
When the system and the detector is reset after an alarm, the LEDs will
return to the normal blink mode if programmed.
Note that only five detectors on any one SLC can latch on the detector
LEDs in the alarm condition. However, if the detectors are designed to
limit the current drawn from the SLC, the system can be programmed to
latch on more LEDs when additional detectors are in alarm. This mode is
needed if a relay or sounder detector mounting base is used when
controlling an auxiliary function such as equipment control or local
signaling, or if a duct smoke detector relay controls a HVAC fan.
Remote LED annunciation capability is available as an optional accessory
(RA400Z).

CAUTION: Personal injury hazard. This device will not
operate without electrical power. Frequently, fire
situations may cause an interruption of power. The
system safeguards should be discussed with your
local fire protections specialist.

Johnson Controls smoke detectors are marked with a compatibility
identifier located as the last digit of the five digit code stamped on the base
of the product. Connect detectors only to compatible control units as
indicated in Johnson Controls compatibility chart, which contains a list of
UL Listed control units and detectors. See the Device Compatibility
Technical Bulletin located in the Fire Management Accessories Manual
(FAN 445).

Installation Procedures
This section contains installation information for Johnson Controls
5551RJ intelligent rate-of-rise thermal detectors. Instructions are given for
wiring the detector, and basic installation information is provided.
The National Fire Protection Association (NFPA)-72-National Fire
Alarm Code defines the spacing requirements for smoke detectors.
Typically, this is 30 foot centers for mounting (maximum of 21 foot radius
of each detector) when the detectors are installed on a smooth ceiling no
higher than a foot. Room configuration and operating environment may
require a reduction in the standard maximum 900 square foot coverage for
each detector.
All wiring must conform to applicable local codes, ordinances, and
regulations. Verify that all detector bases are installed and the wiring
polarity is correct at each base. 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.
Bases are provided with screw terminals for Signaling Line Circuit (SLC)
communications/power, ground, and remote annunciator connections.
Refer to the selected plug-in detector mounting base document located in
the Fire Initiating Devices and Notification Appliances Technical Manual
(FAN 408) for installation and wiring instructions.
!
WARNING: Equipment hazard. Disconnect power from the
control panel before installing detectors.
If the fire system was previously installed, inform the operator and
appropriate local authorities that the system will be temporarily out of
service.
!
WARNING: Equipment hazard. Remove power from the loop
before installing detectors.

8 Intelligent Products—5551RJ Intelligent Rate-of-Rise Thermal Detector w/ Fixed Temp. Heat Detector
To install detectors:
1. Wire the detector base (supplied separately) per the wiring diagram
provided in the detector base technical bulletin.
2. Set the detector to a desired SLC address on the detector rotary
switches (Figure 1), and then write the address on the label on the
base. Set the detector address by:
●rotating the right dial so that the arrow points to the address
unit digit
●rotating the left dial so that the arrow points to the address
decade digit
3. Install the detector into the detector base.
4. Turn the detector clockwise until it drops into place.
5. Continue turning the detector clockwise to lock it in place.
6. Enable the tamper-proof feature. For instructions see the
Tamper-Proof Feature section of this technical bulletin.
7. After all detectors have been installed, apply power to the SLC or
control unit.
8. Remove the detector dust cover if the operating environment is free of
excessive dust as is typically encountered during construction.
9. Test the detector by following the procedure in the Testing section of
this technical bulletin.

Figure 1: Rotary Decade Address Switches
Dust covers can be used to help limit dust entry to the detector, but they
are not a substitute for removing the detector during building construction.
If detectors are mounted in a construction area, with or without the dust
cover in place, each detector should be thoroughly cleaned, inspected, and
tested after construction is complete. Remove any dust covers before
placing system in service.

This detector includes a tamper-proof feature that prevents removal of the
detector without the use of a tool.
To make the detector tamper-proof:
1. Break off the smaller tab at the scribed line on the tamper proof tab on
the detector mounting bracket.
2. Install the detector.

To remove the detector from the bracket once it has been made
tamper-proof:
1. Use a pocket screwdriver, or similar tool, and depress the
tamper-proof tab located in the slot on the mounting bracket.
2. Turn the detector counterclockwise until it separates from the base.
See the applicable detector base data for the location of the tamper-proof
break-off tab and the location of the tool insertion point.
