Before Installing
Please thoroughly read the System Sensor manual I56-407,
Guide for Proper Use of System Smoke Detectors,
which
provides detailed information on detector spacing, place-
ment, zoning, wiring, and special applications. Copies of
this manual are available at no charge from System Sensor.
NFPA 72 and NEMA should be observed. (For installa-
tion in Canada, refer to CAN/ULC-S524,
Standard for the
Installation of Fire Alarm Systems
and CEC Part 1, Sec.

General Description
Models B401BH and B401BHA sounder bases are intended
for use with System Sensor 400 Series plug-in sensor heads
in conventional 2-wire plug-in systems. Refer to systems
manuals for the maximum allowable number of units per
loop. The B401BH requires an external 24VDC (nominal)
supply with reverse polarity capability. The connections of
the external supply (terminals 1 and 2) and the initiating
loop (terminals 3, 4, and 5) are isolated in the B401BH to
prevent electrical interaction between them.
