Intelligent Products—2551J and 2551TJ Plug-In Intelligent Photoelectronic Smoke Detector 7
Installation Procedures
This section contains installation information for Johnson Controls 2551J
and 2551TJ plug-in intelligent photoelectronic smoke 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 10 feet. 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.
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.
