INSTALLATION INSTRUCTIONS
www.wheelockinc.com 115VAC MULTITONE STROBE APPLIANCE
MT4-115
Use this product according to this instruction manual. Please keep this instruction manual for future reference.
GENERAL:
115VAC Multitone Strobe Signals are UL Listed for private mode Fire Protective Service and for General Signaling Service. They
are listed for both indoor and outdoor use with the backboxes specified in these instructions (See Mounting Information).
115VAC Multitone Strobe Signals can be field set to produce any one of eight commonly used alarm tones. Sound output can be
field set to provide either HIGH (HI) dBA or STANDARD (STD) dBA sound output level. They are available with a 115VAC
Xenon Tube Strobe with an intensity of 15 candela (cd).
The 115VAC Multitone Strobe Signals have separate input terminals for alarm tone activation and strobe activation. Shunt wires are
provided to operate both the alarm tone and the strobe simultaneously on a single input circuit (See Wiring Diagram). All inputs have
a DC blocking capacitor for compatibility with supervision
when used with a Fire Alarm Control Panel (F.A.C.P.).
NOTE: All CAUTIONS and WARNINGS are identified by the symbol
. All warnings are printed in bold capital letters.
WARNING: PLEASE READ THESE INSTRUCTIONS CAREFULLY BEFORE USING THIS PRODUCT. THE
MULTITONE STROBE SIGNALS MUST BE FIELD SET TO THE DESIRED dBA SOUND OUTPUT LEVEL AND
ALARM TONE BEFORE THEY ARE INSTALLED. THIS IS DONE BY PROPERLY INSERTING A JUMPER PLUG
AND ADJUSTING A FOUR POSITION SWITCH IN ACCORDANCE WITH THESE INSTRUCTIONS. INCORRECT
SETTINGS WILL RESULT IN IMPROPER PERFORMANCE AND MAY DAMAGE THE PRODUCT AND COULD
RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS.
CAUTION: NOT RECOMMENDED FOR USE AT REGRIGERATOR / FREEZER DOOR ENTRANCES OR OTHER
AREAS WITH PERSISTENT CONDENSATIONS.

GENERAL NOTE:
If the strobe and audible are wired to operate in unison on a single circuit, add strobe current from Table 1 to audible signal current
from Table 3 to obtain total current for each unit.
WARNING: IF MULTITONE STROBE SIGNALS ARE OPERATED WITHIN 15 INCHES OF A PERSON'S EAR, THEY CAN
PRODUCE A SOUND PRESSURE LEVEL THAT EXCEEDS THE MAXIMUM 120 dBA PERMITTED BY ADA AND OSHA RULES.
EXPOSURE TO SUCH SOUND LEVELS CAN RESULT IN DAMAGE TO A PERSON'S HEARING.
WARNING: MAKE SURE THAT THE TOTAL RMS CURRENT REQUIRED BY ALL APPLIANCES THAT ARE CONNECTED
TO THE SYSTEM’S PRIMARY AND SECONDARY POWER SOURCES 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 and 3 to determine the highest value of “RMS Current” for an individual strobe
(across the expected operating voltage range of the stro be), then multiply these values by the total number of strobes; be sure to add
the currents for any other appliances, including audible signaling appliances, powered by the same source and include any required
safety factors.
WARNING: MAKE SURE THAT ALL FUSES USED ON SIGNALING CIRCUITS ARE RATED TO HANDLE THE MAXIMUM
INRUSH OR PEAK CURRENT FROM ALL DEVICES ON THOSE CIURCUITS. FAILURE TO DO THIS MAY RESULT IN LOSS OF
POWER TO THE SIGNALING CIRCUIT AND THE FAILURE OF ALL DEVICES ON THAT CIRCUIT TO OPERATE, WHICH
COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS.
The Multitone audible signals produce a brief inrush current that lasts for just 50 microseconds but can reach a peak value of 5.0
Amps.
