(800) 631-2148 SERIES HS4-24MCWH MULTI-HIGH-CANDELA FOUR WIRE APPLIANCES
www.wheelockinc.com (WALL MOUNT VERSIONS)
Use this product according to this instruction manual. Please keep this instruction manual for future reference.
GENERAL:
Wheelock’s Series HS4-24MCWH Multi-Candela Horn Strobe provides four selectable candela settings (15, 30, 75, 110). The HS4-24MCWH allows 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 HS4-24MCWH appliance is UL Listed
under Standard 1971 for Signaling Applicances for the Hearing Impaired and UL Standard 464 for Audible Signal Appliances. It is listed for indoor use only
be mounted to double-gang, 4” backbox, 100mm European backbox or SHBB surface backbox (See wiring and mounting information). This appliance is listed for wall
mounting only. The HS4-24MCWH appliance uses a xenon flashtube with solid state circuitry enclosed in a polycarbonate lens to provide maximum visibility and
reliability for effective visible signaling.
The horn portion of the HS4-24MCWH 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 (MED) 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 Code 3 Horn should be used only for fire evacuation signaling and not for any other purpose.
The HS4-24MCWH 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.
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 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. The strobe will produce 1 flash per second over the "Regulated Voltage" range.
2. This horn/strobe model meets the required light distribution patterns defined in UL1971.
3. This model is UL Listed for indoor use with a temperature range of +32°F to +120°F (0°C to +49°C) and maximum humidity of 93% ± 2% RH. The effect of
shipping and storage temperatures shall not adversely affect the performance of the appliance when it is stored in the original cartons and not subjected to misuse
or abuse.
WARNING: CANDELA SETTING WILL DETERMINE THE CURRENT DRAW OF THE PRODUCT.

When calculating the total current: Use Tables 3 & 3A 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: 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 figure 4.

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 PROPERTY DAMAGE AND
SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS.

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.

• Use needle nose pliers to pull and properly insert the jumper plug.
• No jumper plug is needed for continuous horn setting. However, it is
recommended that the jumper plug be retained in the unit for future
use (if needed) as shown in Figure 2.
• The HS4 must be set for Code 3 horn when used with the sync
module. Refer to instruction sheets for SM (P83123), DSM
(P83177) or Wheelock power supplies for additional information. If
the HS4 audible is connected to a coded system, the continuous horn
setting must be used
