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:

Cooper 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.

NOTE: All CAUTIONS and WARNINGS are identified by the symbol

. All warnings are printed in bold capital letters.

WARNING: THE AH-WP APPLIANCE IS A "FIRE ALARM DEVICE - DO NOT PAINT."

WARNING: PLEASE READ THESE INSTRUCTIONS CAREFULLY BEFORE USING THIS PRODUCT. FAILURE TO COMPLY WITH
ANY OF THE FOLLOWING INSTRUCTIONS, CAUTIONS AND WARNINGS COULD RESULT IN IMPROPER APPLICATION,
INSTALLATION AND/OR OPERATION OF THESE PRODUCTS IN AN EMERGENCY SITUATION, WHICH COULD RESULT IN PROPERTY
DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS.

NOTES:

1. All models are UL/ULC Listed for indoor and outdoor use with a temperature range of -31

o

98% RH.

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.

WARNING: FOR UL APPLICATIONS THESE APPLIANCES WERE TESTED TO THE OPERATING VOLTAGE LIMITS OF 16-33 VOLTS
FOR 24V MODELS AND 8-17.5 VOLTS FOR 12V MODELS 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 AND 10.5-15.6 VOLTS FOR 12V MODELS USING FILTERED (DC) OR UNFILTERED FULL-WAVE-RECTIFIED (FWR).
APPLY 80% AND 110% OF THESE VOLTAGE VALUES FOR SYSTEM OPERATION.

WARNING: MAKE SURE THAT THE TOTAL RMS CURRENT, TOTAL AVERAGE CURRENT AND TOTAL PEAK CURRENT REQUIRED
BY ALL APPLIANCES THAT ARE CONNECTED TO THE SYSTEM’S PRIMARY AND SECONDARY POWER SOURCES, NAC CIRCUITS, SM,
DSM SYNC MODULES OR WHEELOCK’S POWER SUPPLIES DO NOT EXCEED THE POWER SOURCES’ RATED CAPACITY OR THE
CURRENT RATINGS OF ANY FUSES ON THE CIRCUITS TO WHICH THESE APPLIANCES ARE WIRED. OVERLOADING POWER
SOURCES OR EXCEEDING FUSE RATINGS COULD RESULT IN LOSS OF POWER AND FAILURE TO ALERT OCCUPANTS DURING AN
EMERGENCY, WHICH COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS.

When calculating the total currents: Use Table 1 to determine the highest value of “RMS Current” for an individual AH Appliance (across the expected
operating voltage range of the AH Appliance) or use Table 1A to determine the highest value of “Rated Average Current” of an individual AH Appliance (across
the expected voltage range of the AH Appliance), then multiply these values by the total number of AH Appliances; be sure to add the currents for any other
appliances, powered by the same source and include any required safety factors.

If the peak current exceeds the power supplies’ peak capacity, the output voltage provided by the power supplies may drop below the listed voltage range of the
appliances connected to the supply and the voltage may not recover in some types of power supplies. For example, an auxiliary power supply that lacks filtering
at its output stage (either via lack of capacitance and/or lack of battery backup across the output) may exhibit this characteristic.

CAUTION: Audible Horn appliances are not designed to be used on coded systems in which the applied voltage is cycled on and off.

WARNING: THE AUDIBLE HORN APPLIANCES MUST BE FIELD SET TO THE DESIRED TONE AND dBA SOUND OUTPUT LEVEL
BEFORE THEY ARE INSTALLED. THIS IS DONE BY PROPERLY INSERTING A JUMPER PLUG IN ACCORDANCE WITH THESE
INSTRUCTIONS. INCORRECT SETTINGS WILL RESULT IN IMPROPER PERFORMANCE, WHICH COULD RESULT IN PROPERTY
DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS.
