Intelligent Products—2251J Plug-In Low Profile Intelligent Photoelectronic Smoke Detector 7
Installation Procedures
This section contains installation information for Johnson Controls 2251J
intelligent photoelectronic detectors. Instructions are given for spacing the
detector, and basic wiring 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 be installed in compliance with all applicable local codes,
ordinances, 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.
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.
