SERIES AS AUDIBLE STROBE APPLIANCES

GENERAL:

Wheelock’s Series AS Audible Strobe Appliances are the industry’s first 2-wire horn strobe alarm appliance that provides a selectable continuous or code 3 horn tone
and continuous strobe when connected directly to the fire alarm control panel (FACP), or provide a synchronized code 3 horn tone and synchronized strobe when used
in conjunction with a Sync Module (SM), Dual Sync Module (DSM) or Wheelock power supplies. The AS Appliances are UL Listed under Standard 1971 for
Emergency Appliances for the Hearing Impaired and UL Standard 464 for Audible Signal Appliances. The 1575W candela wall mounted strobes are listed at 15
candela under UL Standard 1971 and meet 75 candela intensity on axis with low current draw. They are listed for wall mounting and indoor use only
with a universal mounting plate (UMP) that can be mounted to single-gang, double-gang, 4” backbox, 100mm European backbox or SHBB surface backbox (See wiring
and mounting information). The AS Appliances use a xenon flashtube with solid state circuitry enclosed in a polycarbonate lens to provide maximum visibility and
reliability for effective visible signaling.

Series AS Appliances can be field set to provide either high (HI) dBA, medium (MED) dBA or low (LO) dBA sound output.

These strobe 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 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.

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. Strobe will produce 1 flash per second over the "Regulated Voltage" range.

2. These strobe/horn models meet the required light distribution patterns defined in UL 1971.

3. These models are UL/ULC Listed for indoor use with a temperature range of +32ºF to +120ºF (0ºC to +49ºC) 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.

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

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

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.

When calculating the total current: Use Table 3 to determine the highest value of “RMS Current” for an individual AS Appliance then multiply the value by the total
number of AS Appliances. Be sure to add the currents for any other appliances powered by the same source and 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: 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. LIGHT DISTRIBUTION PER UL 1971:

SOUND OUTPUT (SPL) SETTINGS:

WARNING: THE AUDIBLE STROBE 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.
