Before Installing
Please read the System Smoke Detector Application Guide,
which provides detailed information on sensor spacing. place-
ment, zoning, wiring, and special applications. Copies of this
manual are available from System Sensor. NFPA 72 and NEMA
guidelines should be observed.
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 requirements.
The detector should be cleaned at least once a year.
General Description
The B501BHT-2 sounder base is used with System Sensor 200
Series sensor heads. Refer to the appropriate manual for more
information on sensors.
The B501BHT-2 incorporates the distinctive three-pulse tempo-
ral pattern fire alarm evacuation signal now required by NFPA
72 for commercial and residential applications.
The sounder base is intended for use with intelligent systems.
Refer to the panel manual for the maximum allowable num-
ber of units per loop. The sounder base requires an external
24VDC supply with reverse polarity capability or a relay mod-
ule configured to reverse the power as in Figure 5. The con-
nections for the external supply (terminals 1 and 2) and the
communication loop (terminals 3 and 4) are isolated to pre-
vent electrical interaction between them.
A loop of horns can be made to sound by reversing the polar-
ity of the external supply when configured as in Figure 4 and
5. When configured as in Figure 5, a loop of horns can also be
made to sound by turning on the Intelligent Relay Module.

Mounting
Mount the B501BHT-2 directly to an electrical box, using the
mounting kit, supplied (see Figure 2).
The sounder base is 1.1-inches deep. Electrical boxes must be
4-inches square by at least 1 1 ⁄ inches deep - 2
2
ommended.
NOTE: A maximum space of 1 ⁄ inch from the outside edge of
8
the electrical box to the inside edge of the drywall or ceiling
tile is allowable.
Wiring Guidelines
All wiring must be installed in compliance with the National
Electrical Code and the local codes having jurisdiction and
must not be of such length or wire size which would cause
the base to operate outside of its published specifications. The
conductors used to connect smoke sensors 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.
