INSTRUCTIONS
SERIES AH-WP INDOOR/OUTDOOR AUDIBLE HORN APPLIANCES
Use this product according to this instruction manual. Please keep this instruction manual for future reference.
GENERAL:
Wheelock’s AH-WP Audible Horn Appliances are designed to provide a selectable continuous horn or code 3 tone when
connected directly to the Fire Alarm Control Panel (FACP), or provide a synchronized code 3 horn when used in conjunction
with a Sync Module (SM), Dual Sync Module (DSM) or Wheelock’s Power Supplies. The AH-WP Appliances are UL Listed
under UL Standard 464 for Audible Signal Appliances. The AH-24WP is ULC Listed under Standard CAN/ULC-S525-99 for
Audible Signaling Appliances. They are listed for indoor and outdoor use and can be mounted to a 4” backbox (See Mounting
Options).
AH-WP Appliances can be field set to provide either High (HI) dBA, Medium (MED) dBA or Low (LO) dBA sound output.
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.
NOTE:
The code 3 horn incorporates the temporal pattern (1/2 second on, 1/2 second off, 1/2 second on, 1/2 second off, 1/2
second on, 1-1/2 off and repeat) specified by ANSI/NFPA for standard emergency evacuation signaling.
The code 3 horn shall
be used only for fire evacuation signaling and not for any other purpose.
