Notifier BX-501 Smoke Detector Base

The Notifier BX-501 base comes intended for use in a 2-wire intelligent system, with screw terminals provided for power (+) and (-), and remote annunciator connections. Besides, communication takes place over the power (+) and (-) lines. Also, used with the Notifier model CPX-551 ionization and SDX-551 photoelectronic smoke detector heads.

In general, Notifier BX-501 mounts directly to 3-1/2 inch and 4-inch octagon boxes, 4-inch square boxes (with or without plaster rings), and single gang boxes. To mount, remove the decorative ring by turning it in either direction to unhook the snaps, then separate the ring from the base. Install the base to the box using the screws supplied with the junction box and the appropriate mounting slots in the base. Place the decorative ring onto the base, then turn in either direction until the ring snaps in place.

In addition, all wiring must be installed in compliance with the National Electrical Code and the local authorities having jurisdiction. Proper wire gauges should be used. The conductors used to connect smoke detectors to control panels and accessory devices should be color-coded to prevent wiring mistakes. Improper connections can prevent a system from responding properly in the event of a fire.
