All AH-WP models are designed for use with either filtered DC (VDC) or unfiltered Full-Wave-Rectified (FWR) input voltage.
All inputs are polarized for compatibility with standard reverse polarity supervision of circuit wiring by a FACP.

second on, 1-1/2 off and repeat) specified by ANSI/NFPA for standard emergency evacuation signaling. The code 3 horn shall
