INSTALLATION INSTRUCTIONS
INDOOR/OUTDOOR AUDIBLE HORN APPLIANCES
IMPORTANT –
All audible and visual signaling appliances must be
installed in accordance with all applicable national and local fire
alarm codes and any other required regulatory agency.
Series AH-R-WP Appliances provide a selectable Continuous or
Code 3 Horn tone when connected directly to the Fire Alarm Control
Panel (FACP). They can also provide a synchronized code 3 or
march time horn tone when connected to a notification appliance
circuit running the Siemens sync protocol. The AH-R-WP
Appliances are UL Listed under UL Standard 464 for Audible Signal
Appliances. The AH-R-WP 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-R-WP Appliances can be field set to provide either High (HI)
dBA, Medium (MED) dBA or Low (LO) dBA sound output.
AH-R-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.

Refer to the installation instructions for the appropriate NAC to find the maximum allowed voltage drop. Use this value along with the current draw
for the appliance to determine the allowable wire resistance.
WARNING: FOR UL APPLICATIONS THESE APPLIANCES WERE TESTED TO THE OPERATING VOLTAGE LIMITS OF 16-33 VOLTS
FOR 24V MODEL USING FILTERED (DC) OR UNFILTERED FULL-WAVE-RECTIFIED (FWR). DO NOT APPLY 80% AND 110% OF THESE
VOLTAGE VALUES FOR SYSTEM OPERATION.
WARNING: FOR ULC APPLICATIONS THESE APPLIANCES WERE TESTED TO THE OPERATING VOLTAGE LIMITS OF 20-31 VOLTS
FOR 24V MODELS USING FILTERED (DC) OR UNFILTERED FULL-WAVE-RECTIFIED (FWR). APPLY 80% AND 110% OF THESE
VOLTAGE VALUES FOR SYSTEM OPERATION.
