FSP-951 + B501

The NOTIFIER FSP-951 is an intelligent addressable photoelectric smoke detector designed for FlashScan and CLIP protocol systems, featuring advanced optical sensing for early fire detection across various combustion sources.
It requires a compatible base like the B501 standard base for mounting and wiring to the SLC loop, providing rotary decimal addressing (1-159 FlashScan, 1-99 CLIP) with dual-color LEDs for 360° status indication.
