General Description
This B401A plug-in detector base is used with System
Sensor smoke and heat detector heads. The capability of
plugging these detectors into a variety of special bases
makes them more versatile than equivalent direct-wired
models. Refer to the System Sensor catalog for other
available plug-in detector bases.
The B401A base is intended for use in 2-wire systems, with
screw terminals provided for power and remote annuncia-
tor connections.

Attach the base to the box using the screws supplied with the junction box. SHORTING SPRING Installation Guidelines All wiring must be installed in compliance with applicable codes and the authority having jurisdiction. Proper wire gaug- es should be used. The conductors used to connect smoke detectors to control panels and accessory devices should be color-coded to reduce the likelihood of wiring errors. Improper connections can prevent a system from responding properly in the event of a fire. For signal wiring (the wiring between interconnected detec- tors), it is recommended that the wire be no smaller than 18 gauge. Wire sizes up to 12 gauge may be used with the base. For best system performance, the power (+) and (–)
