P84150 MTWP WEATHERPROOF “GENERAL INFORMATION” SHEET (P82380) ON THESE PRODUCTS. THESE DOCU-
MENTS DO UNDERGO PERIODIC CHANGES. IT IS IMPORTANT THAT YOU HAVE CURRENT INFORMATION ON THESE
PRODUCTS. THESE MATERIALS CONTAIN IMPORTANT INFORMATION THAT SHOULD BE READ PRIOR TO SPECIFYING
OR INSTALLING THESE PRODUCTS, INCLUDING:
• TOTAL CURRENT REQUIRED BY ALL APPLIANCES CONNECTED TO SYSTEM SECONDARY POWER SOURCES.
• FUSE RATINGS ON NOTIFICATION APPLIANCE CIRCUITS TO HANDLE PEAK CURRENTS FROM ALL APPLI-
ANCES ON THOSE CIRCUITS.
• COMPOSITE FLASH RATE FROM MULTIPLE STROBES WITHIN A PERSON’S FIELD OF VIEW.
• THE VOLTAGE APPLIED TO THESE PRODUCTS MUST BE WITHIN THEIR RATED INPUT VOLTAGE RANGE.
• INSTALLATION IN OFFICE AREAS AND OTHER SPECIFICATION AND INSTALLATION ISSUES.
• USE STROBES ONLY ON CIRCUITS WITH CONTINUOUSLY APPLIED OPERATING VOLTAGE. DO NOT USE STROBE
ON CODED OR INTERRUPTED CIRCUITS IN WHICH THE APPLIED VOLTAGE IS CYCLED ON AND OFF AS THE
STROBE MAY NOT FLASH.
• FAILURE TO COMPLY WITH THE INSTALLATION INSTRUCTIONS OR GENERAL INFORMATION SHEETS COULD
RESULT IN IMPROPER INSTALLATION, APPLICATION, AND/OR OPERATION OF THESE PRODUCTS IN AN EMER-
GENCY SITUATION,WHICH COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU
AND/OR OTHERS.
• CONDUCTOR SIZE (AWG), LENGTH AND AMPACITY SHOULD BE TAKEN INTO CONSIDERATION PRIOR TO DE-
SIGN AND INSTALLATION OF THESE PRODUCTS, PARTICULARLY IN RETROFIT INSTALLATIONS.
Wheelock products must be used within their published specifications and must be PROPERLY specified, applied, in-
stalled, operated, maintained and operationally tested in accordance with their installation instructions at the time of
installation and at least twice a year or more often and in accordance with local, state and federal codes, regulations and
laws. Specification, application, installation, operation, maintenance and testing must be performed by qualified person-
nel for proper operation in accordance with all of the latest National Fire Protection Association (NFPA), Underwriters’
Laboratories (UL), National Electrical Code (NEC), Occupational Safety and Health Administration (OSHA), local, state,
county, province, district, federal and other applicable building and fire standards, guidelines, regulations, laws and
codes including, but not limited to, all appendices and amendments and the requirements of the local authority having
jurisdiction (AHJ).
The notification appliance shall be a Wheelock Series MT audible/visual appliance or equivalent. Notification appliance
shall be electronic and use solid state components. Electromechanical alternatives are not approved. Each electronic
appliance shall provide eight (8) field selectable alarm tones. The tones shall consist of: HORN, BELL, MARCH TIME
HORN, CODE-3 HORN, CODE-3 TONE, SLOW WHOOP, SIREN and HI/LO. Tone selection shall be by durable dip
switch assembly and not clips or jumpers. The Multitone Audible appliance shall be UL Listed under Standard 464 for
Audible Signal Appliances. The audible and the strobe shall be able to operate from a single NAC circuit while
producing any of these tones. The appliance shall provide two output sound levels: STANDARD and HIGH dBA. The
HIGH dBA setting shall provide a minimum 5 dBA increase in sound output at nominal voltage. The HIGH anechoic dBA
measurement at 10 feet at the alarm HORN SETTING shall be 101 dBA minimum for MT and 92 dBA minimum for MT
Strobes, at nominal voltage. Operating voltages shall be either 12 VDC or 24 VDC using filtered power or unfiltered
power supply (full-wave-rectified). All models shall have provisions for standard reverse polarity type supervision and
IN/OUT field wiring using terminals that accept #12 to #18 AWG wiring.
Combination audible/visual appliances shall incorporate a Xenon flashtube enclosed in a rugged Lexan
® lens or
equivalent with solid state circuitry. Strobe shall produce a flash rate of one (1) flash per second minimum over the
voltage range. The strobe intensity shall be rated per UL and Listed under Standard 1971 for Signaling Devices for the
Hearing Impaired for 1575 or 75 candela. The 1575 candela strobe shall be specified when 15 candela or with 75
candela intensity on-axis is required. Strobe Models shall incorporate circuitry for synchronized strobe flash and shall
be designed for compatibility with Wheelock SM and/or DSM Sync Modules or a Power Supply with Wheelock’s Sync
Protocol. The strobes shall not drift out of synchronization at any time during operation. If the module fails to operate
(i.e., contacts remain closed), the strobes shall revert to a non-synchronized default flash rate.
Strobe activation shall be via independent input or from the same input circuit as the audible.
The combination audible/visual appliances shall be installed indoors and may be surface or flush mounted. They shall
mount to standard electrical hardware requiring no additional trimplate or adapter. The aesthetic appearance shall not
have any mounting holes or screw heads visible when the installation is completed. The appliance shall be finished in
a textured red color.
The Series MT-12/24 audible appliance may be installed indoor or outdoor with the proper back box.
For Weatherproof applications where specifications require 75 cd @ -31°F (-35°C) and full temperature range
of -31°F to 150°F refer to Data Sheet S9004 and/or Installation Instructions P84150.
