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.
Power
Wire leads are provided for 24 VAC/DC power operation.
