The B200S-LF-WH and B200S-LF-IV sounder bases are used with addressable detector heads. For a list of compatible sensors, refer to the System Sensor website at www.systemsensor.com. Refer to the appropriate manual for more information on sensors.
The B200S-LF-WH/B200S-LF-IV low frequency sounder base generates a low frequency tone around 520 Hz. Studies have shown that low frequency audible devices that operate around 520 Hz are more effective in waking individuals in sleeping areas.
The sounder base is capable of producing a variety of tone patterns, including the distinctive three-pulse temporal pattern (ANSI Temporal 3) fire alarm signal now required by NFPA 72 for commercial and residential applications.
The B200S-LF-WH/B200S-LF-IV offers maximum flexibility in configuration and operation to meet or exceed the requirements of UL268 and UL464 for Continuous, Temporal 3 and March time patterns. The temporal 4 pattern meets all requirements of UL268 and UL2075, as well as, private mode setting of UL 464.
The B200S-LF-WH/B200S-LF-IV can be commanded by the Fire Alarm Control Panel (FACP) to adopt the address of the attached sensor head, but as a unique device type on the loop. By using the address, the FACP can command an individual sounder base to activate, or a group of sounders in a suite or other multi-room configuration. The command set from the panel can be tailored to the specific event, allowing selection of volume, tone, and group.
The device offers two volume levels: 75 dBA and 85 dBA. The available tones are Continuous, ANSI Temporal 3, ANSI Temporal 4, and March Time. In addition, some panels will offer the ability to command a custom tone pattern.
Refer to the appropriate FACP manual for more information.
