GENERAL:

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

The Multitone Strobe Weatherproof Appliances are UL Listed under Standard 1638 (Visual Signaling Appliances) and Standard 1971 (Signaling Devices for the
Hearing Impaired) for indoor/outdoor use, Fire Protective Service and UL Standard 464 for Audible Signal Appliances. Models with amber, blue, green or red lens are
not UL approved. The MTWP-2475W is ULC Listed under Standard CAN/ULC-S526-02 for Visual Signaling and under Standard CAN/ULC-S525-99 for Audible
Signal Devices for Fire Alarm Systems Appliance . The Multi-High-Candela strobe provides two selectable light output intensities in one unit. An outdoor backbox is
required for outdoor installation. The Multitone Strobe Appliances use a xenon flashtube with solid state circuitry enclosed in a polycarbonate lens to provide
maximum visibility and reliability for effective visible signaling.

Multitone Strobe Appliances 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.

All Multitone Strobe models are designed for use with either filtered DC or unfiltered full-wave-rectified (FWR) input voltage. The Multitone Strobe Appliances 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 are polarized for compatibility with standard reverse polarity supervision of circuit wiring by a fire alarm control
panel (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 the
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, 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.

CAUTION: NOT RECOMMENDED FOR USE AT REFRIGERATOR / FREEZER DOOR ENTRANCES OR OTHER AREA WITH PERSISTENT CONDENSATION.

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

2. All models are listed for indoor and outdoor use. UL 1971 is tested from a temperature range of 32ºF to 120ºF (0ºC to 49ºC). UL 1638 is
tested from a temperature range of -40ºF to +150ºF (-40ºC to +66ºC) with a maximum humidity of 98% ±2% RH.. The effect of shipping
and storage temperatures shall not adversely affect the performance of the appliances when it is stored in the original cartons and is not
subjected to misuse or abuse

3. Candela ratings in Table 1 are rated for clear lens. Derate approximately 24% for amber, 55% for green, 70% for blue and 80% for red.

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 APPLIED VOLTAGE TO THE STROBES. THE MAXIMUM WIRE IMPEDENCE BETWEEN
STROBES SHALL NOT EXCEED 35 OHMS.

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

Use Tables 2, 2A and 2B to determine the highest value of “Rated Current” for an individual Multitone Strobe (across the expected operating voltage range of the
Multitone Strobe). Add strobe current from Table 2B a audible appliance current from Table 2 and Table 2A to obtain total current for each unit, if the strobe and

A

same source and include any required safety factors.

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

WARNING: MAKE SURE THAT THE TOTAL RATED 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.
