Before Installing
Please thoroughly read System Sensor's manual I56-407,
Guide for Proper Use of System Smoke Detectors. This
manual provides detailed information on detector spacing,
placement, zoning, wiring, and special applications, and is
available at no charge from System Sensor.
NOTICE: This manual should be left with the owner/user
of this equipment.
IMPORTANT: The detector used with this base must be
tested and maintained regularly following NFPA 72 re-
quirements. The detector used with this base should be
cleaned at least once a year.
General Description
The B404BT detector base is designed for use with Sys-
tem Sensor model 2451 and 2451TH photoelectronic and
1451 ionization detector heads. The capability of plug-
ging 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 bases. The B404BT base is intended for
use in 4-wire systems with terminals provided for re-
mote annunicator and relay connections.
