INSTALLATION INSTRUCTIONS
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 agencies.
Series AH 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 Appliances are UL Listed
under UL Standard 464 for Audible Signal Appliances and ULC Listed
under Standard CAN/ULC-S525-99 for Audible Signaling Appliances.
They are listed for indoor use only
and are equipped with a
Universal Mounting Plate (UMP) that can be mounted to single-gang,
double-gang, 4” square backbox, 100mm European or SHBBS
surface backbox (See Mounting Options).
AH Appliances can be field set to provide either High (HI) dBA,
Medium (MED) dBA or Low (LO) dBA sound output. All AH models
are designed for use with either filtered DC 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.

WARNING: CHECK THE MINIMUM AND MAXIMUM OUTPUT OF THE POWER SUPPLY AND STANDBY BATTERY AND SUBTRACT THE
VOLTAGE DROP FROM THE CIRCUIT WIRING RESISTANCE TO DETERMINE THE APPLIED VOLTAGE TO THE SIGNALING APPLIANCE.
FOR UL APPLICATIONS THESE APPLIANCES WERE TESTED TO THE OPERATING VOLTAGE LIMITS OF 16-33 VOLTS FOR 24V MODELS
USING FILTERED (DC) OR UNFILTERED FULL-WAVE-RECTIFIED (FWR). DO NOT APPLY 80% AND 110% OF THESE VOLTAGE VALUES
FOR SYSTEM OPERATION.
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.
