GENERAL:

Series HS4-24MCW and HS4-24MCC Multi-Candela Horn Strobe provides four selectable candela settings (15, 30, 75, 110 and 15/30/75/95 respectively). These
models allow for independent operation of the strobe circuit and the horn circuit. It is the ideal choice for retrofit applications as well as new installations. The HS4
appliance is UL Listed under Standard 1971 for Signaling Applicances for the Hearing Impaired and UL Standard 464 for Audible Signal Appliances. The HS4­24MCW is also ULC Listed under Standard CAN/ULC-S526-02 for Visual Signaling Appliances and Standard CAN/ULC-S525-99 for Audible Signaling Appliances
for Fire Alarm Systems. It is listed for
appliance is listed for
enclosed in a polycarbonate lens to provide maximum visibility and reliability for effective visible signaling.

The horn portion of the HS4 appliance can be field set to provide either a continuous horn when connected directly to the fire alarm control panel (FACP), or a
synchronized code 3 horn when used in conjunction with the Sync Module (SM), Dual Sync Module (DSM) or Wheelock power supplies. The horn can be field set to
provide either high (HI) dBA, medium (ME D ) dBA or low (LO) dBA sound output.
NOTE: The Code 3 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) is specified by ANSI and
NFPA 72 for standard emergency evacuation signaling.

The HS4 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 an FACP.

NOTE: All Canadian Installations should be in accordance with the Canadian Standard for the Installation of Fire Alarm Systems – CAN/ULC-S524-01 and Canadian
Electrical Code, Part 1. Final acceptance is subject to authorities having jurisdiction (AHJ).

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, CANDELA SETTING, INSTALLATION AND/OR OPERATIO N OF
THESE PRODUCTS IN AN EMERGENCY SITUATION, WHICH COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR
OTHERS.

When calculating the total current: Use Tables 3, 3A & 3B to determine the highest value of “RMS Current” for an individual HS4 then multiply the value by the total
number of HS4 Appliances. Be sure to add the currents for any other appliances powered by the same source and to include any required safety factors.

NOTE: The maximum number of strobes on a single notification appliance circuit shall not exceed 50.

CAUTION: These notification appliances are UL Listed as “Regulated”. They are intended to be used with FACPs whose notification circuits are UL Listed as

“Regulated.” These appliances shall not be used on UL Listed “Special Application” notification circuits unless the appliances are identified to be compatible in the
installation instructions of the FACP or unless the FACP is identified to be compatible in this instruction manual.

WARNING: CANDELA SETTING WILL DETERMINE THE CURRENT DRAW OF THE PRODUCT.

WARNING: THESE APPLIANCES WERE TESTED TO THE REGULATED VOLTAGE LIMITS OF 16.0-33.0 VOLTS FOR 24V MODELS USING FILTERED DC OR

UNFILTERED FULL-WAVE-RECTIFIED VOLTAGE. DO NOT APPLY VOLTAGE OUTSIDE OF THIS RANGE.

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 APPPLIED VOLTAGE TO THE STROBES. THE MAXIMUM WIRE IMPEDANCE BETWEEN
STROBES SHALL NOT EXCEED 35 OHMS.

WARNING: MAKE SURE THAT THE TOTAL RMS CURRENT REQUIRED BY ALL APPLIANCES THAT ARE CONNECTED TO THE SYSTEM’S PRIMARY AND
SECONDARY POWER SOURCES, APPLIANCE CIRCUITS, SM, DSM SYNC MODULES AND WHEELOCK POWER SUPPLIES DOES 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.

CAUTION: The strobe is not designed to be used on coded systems in which the applied voltage is cycled on and off.

NOTE: The horn circuit is compatible with coded systems only if the unit is wired for independent horn and strobe operation per fig ure 4.

Factory setting for HS4-24MCW and MCC is on 15 candela, Medium dB and Code 3.

WARNING: THE CANDELA SELECT SWITCH MUST BE FIELD SET TO THE REQUIRED CANDELA INTENSITY BEFORE INSTALLATION. WHEN CHANGING
THE SETTING OF THE CANDELA SELECT SWITCH, MAKE CERTAIN THAT IT “CLICKS” IN PLACE. AFTER CHANGING THE CANDELA SETTING, THE
APPLIANCE MUST BE RETESTED TO VERIFY PROPER OPERATION. IMPROPER SETTING OF THE CANDELA SELECT SWITCH MAY RESULT IN OPERATION
AT THE WRONG CANDELA, WHICH COULD RESULT IN A CURRENT DRAW EXCEEDING THE POWER SUPPLY’S CAPACITY.

CAUTION: If these appliances are operated within 15 inches of a person's ear, they can produce a sound pressure level that exceeds the maximum 120dBA

permitted by ADA and OSHA rules. Exposure to such sound levels can result in damage to a person's hearing.

WARNING: THE HS4 APPLIANCES MUST BE FIELD SET TO THE DESIRED TONE AND dBA SOUND OUTPUT LEVEL BEFORE THEY ARE INSTALLED. THIS
IS DONE BY PROPERLY INSERTING JUMPER PLUGS 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.
