The LFSBBB-W Low Frequency Sounder Back Box is designed to support the PAD100-LFSB addressable low-frequency sounder base, enabling applications such as single-station operation, grouped activation, or full system-wide notification. It provides compliant low-frequency audible signaling per NFPA 72 and UL 464 and integrates seamlessly into Potter addressable fire alarm systems using PAD sub-point addressing. The unit features field-selectable sensor locking, accessible sounder components, and internal supervision of the 24 VDC sounder power eliminating the need for external supervision relays.
