Before Installing  
NOTE: When not used as a supplementary evacuation system  
the external 24 VDC supply shall be treated as a component of  
the main power supply system and shall fall under the require-  
ments of the main power supply system per NFPA 72.  
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.

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  
Terminals 3 and 4 are used for the communication circuit.  
The B501BHT sounder base is used with System Sensor 200  
and 500 Series sensor heads. Refer to the appropriate manual  
for more information on sensors.  
Mounting  
Mount the B501BHT directly to an electrical box, using the  
mounting kit, supplied (see Figure 2).  
The B501BHT 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 1.1-inches deep. Electrical boxes must  
1
be 4-inches square by at least 1 ⁄2 inches deep - 218 inches is  
recommended.  
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.  
NOTE: A maximum space of 18 inch from the outside edge of  
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.  
When the sensor’s visible LEDs are latched on for approxi-  
mately 10 seconds, the associated horn sounds. A loop of  
horns can be made to sound by reversing the polarity 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.

gether using terminal 5, Sounder Base Interconnect, as shown

UL has approved grouping for up to six B501BHT base with  
horn units. When wired as a group, any detector in the group  
that has its LED’s latched on by the panel will cause other  
B501BHT units in the group to sound. This type of “local”  
grouping is accomplished by wiring the grouped devices to-  
NOTE: Since a local grouping of horns is not supervised, the  
groups can only be used as a supplementary evacuation system.  
It is not acceptable to group horns for primary alarm signaling.
