HS-24 APPLIANCE

Use this product according to this instruction manual. Please keep this instruction manual for future reference.

GENERAL:

The HS-24 Appliance can be field set to provide either Continuous Horn or Code 3 Horn. It can provide a continuous horn tone
when connected directly to the Fire Alarm Control Panel (FACP), or synchronized Code 3 Horn when used in conjunction with
the Sync Module (SM), Dual Sync Module (DSM) or Wheelock’s Power Supplies. Audible Horn Appliance can be field set to
provide either High (HI) dBA, Medium (MED) dBA or Low (LO) dBA sound output and can be used on coded systems in
which the applied voltage is cycled on and off. The HS-24 Appliance is UL Listed under Standard 464 for Audible Signal
Appliances and also ULC Listed under Standard CAN/ULC-S525-99 for Audible Signaling Appliances for Fire Alarm Systems.
It is listed for

indoor use only and can be mounted to double-gang, 4” backbox, 100mm European backbox or SHBB surface

backbox (See Mounting Options).

The HS-24 is 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 Fire Alarm Control Panel (FACP).

NOTES:

1. The HS-24 is UL Listed for indoor use with a temperature range of +32°F to +120°F (0°C to +49°C) an d maximum
humidity of 93% ± 2% RH.

WARNING: FOR UL APPLICATIONS THIS APPLIANCE WAS TESTED TO THE OPERATING VOLTAGE
LIMITS OF 16-33 VOLTS 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 THIS APPLIANCE WAS TESTED TO THE OPERATING VOLTAGE
LIMITS OF 20-31 VOLTS 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 AND TOTAL AVERAGE CURRENT
REQUIRED BY ALL APPLIANCES THAT ARE CONNECTED TO THE SYSTEM’S PRIMARY AND SECONDARY
POWER SOURCES, SIGNALING CIRCUITS, SM, DSM SYNC MODULES AND WHEELOCK’S POWER
SUPPLIES DO NOT EXCEED THE POWER SOURCES’ RATED CAPACITY OR THE CURRENT RATINGS OF
ANY FUSES ON THE CIRCUITS TO WHICH THIS APPLIANCE IS 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.
