PLEASE READ THE DETAIL DESCRIPTION BEFORE PURCHASING. NO RETURNS ALL SALES ARE FINAL. System Sensor B200S-WH Intelligent Addressable Sounder Base, White The B200S-WH and B200S-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-WH and B200S-IV sounder bases were designed specifically to meet the needs of dwelling unit applications. They offer maximum flexibility in configuration and operation to meet or exceed the requirements of UL268 and UL464. 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-WH/B200S-IV can be commanded by the Fire Alarm Control Panel to adopt the address of the attached sensor head, but as a unique device type on the loop. By using the address, the fire alarm control panel 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 fire alarm panels will offer the ability to command a custom tone pattern. Refer to the appropriate fire alarm control panel manual for more information. In addition, the B200S-WH/B200S-IV is equipped with the circuitry to recognize the System Sensor synchronization protocol, enabling the sounder base to be used as a component of the general evacuation signal ? producing an NFPA 72 compliant Temporal 3 pattern in synchronization with other System Sensor notification devices. This requires connection to a power supply capable of generating the System Sensor synchronization pulses, a FACP NAC output configured to System Sensor synchronization protocol, or a separate synchronization module.
