TR-B200S-WH / TR-B200S-IV TR-B200S-LF-WH / TR-B200S-LF-IV

Intelligent Sounder Base


The TR-B200S sounder base series is designed for new and existing commercial dwelling unit applications. It offers maximum flexibility in installation, configuration, and operation to meet or exceed UL 268 and UL 464 requirements.


The sounder base “listens in” to the communication between the attached sensor head and the fire alarm control panel (FACP) to adopt the same address as the detector, but as a unique device type on the loop. The FACP can then use that address to command an individual sounder – or a group of sounders – to activate. In addition, the FACP’s will enable custom tone patterns.


The TR-B200S series sounder bases recognize the System Sensor® synchronization protocol. This enables it to be used as a component of the general evacuation signal – along with other System Sensor horns, horn strobes, and chimes – when connected to a FACP output programmed as sounder base power.


The TR-B200S-LF low frequency sounder base is designed to meet the NFPA 72 sleeping space requirement to produce a fundamental frequency of 520 Hz +/- 10% with a square wave or its equivalent. Studies show that a lower frequency, centered around 520 Hz, is the most ideal to awaken sleeping occupants, even those with mild to severe hearing loss.


The TR-B200S series sounder bases can be mounted directly to 4” (10.16 cm) square, 4” (10.16 cm) octagon, 3 1/2” (8.9 cm) octagon, single-gang or double-gang junction boxes.
