Select Series low-frequency sounder bases are 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. In fact, studies show that a lower frequency, centered around 520 Hz, is the most ideal to wake sleeping occupants, even those with mild to severe hearing loss. Also, the System Sensor B300-6-IV is fully compatible with existing B501BH-Series sounder base installations. The device enables users to select one of two B501-supported tones (ANSI Temporal 3 or Continuous) through a jumper.
The System Sensor B300-6-IV adopts the same address as the detector but uses a unique device type on the loop. Besides, the Fire Alarm Control Panel (FACP) can use that address to command an individual sounder or a group of sounders to activate. The command set from the FACP can be tailor to multiple event-driven tone outputs allowing selection of volume (75 or 85 dBA), tone (ANSI Temporal 3, ANSI Temporal 4 or March Time), and group. In addition, some FACPs will enable custom tone patterns.
The System Sensor B300-6-IV recognizes the System Sensor synchronization protocol. This enables it to be use as a component of the general evacuation signal along with other System Sensor AV appliances; when connected to a power supply or FACP output capable of generating the System Sensor synchronization pulses.
