SOUNDER BASE

The TR-B501BH-3 & TR-B501BH-3/W sounder base are used with

TRIGA intelligent detectors, and it is suitable for indoor use and damp

locations. Refer to the appropriate manual for more information on

detectors.

The TR-B501BH-3 & TR-B501BH-3/W sounder base was designed

specifically to meet the needs of dwelling unit applications. It offers

maximum flexibility in configuration and operation to meet or exceed

the requirements of UL268, UL464.

The sounder base is capable of sounding in high volume or low volume

and is capable of producing either the distinctive three-pulse temporal

pattern (ANSI Temporal 3) fire alarm signal now required by NFPA 72

for commercial and residential applications or a continuous tone by

simply setting toggle switch from the device.

The sounder base is intended for use with intelligent systems. It

includes an isolation circuit, and the isolation circuit enable part of the

communications loop to continue operating when a short circuit

occurs on it. The module will automatically restore the entire communications loop to the normal condition when the short circuit is removed.

The sounder base requires an external 24VDC.
