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

GENERAL:

The Multitone Strobe Appliances can provide a non-synchronized strobe appliance when connected directly to a Fire Alarm Control Panel (FACP), or
provide a synchronized strobe appliance when used in conjunction with a Sync Module (SM), Dual Sync Module (DSM) or Wheelock’s Power Supplies.
All models in the MT Series are for
required for outdoor installation. The Multitone Strobe Appliances use a Xenon flashtube with solid state circuitry enclosed in a rugged Lexan® lens to
provide maximum visibility and reliability for effective visible signaling.

NOTE: “Lexan” is a registered trademark of General Electric Company.

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 CAUTIONS and WARNINGS are identified by the symbol

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.

SPECIFICATIONS:

Model Regulated Voltage

NOTES:

1. Strobes will produce 1 flash per second over the “Regulated Voltage” Range.

2. MT models are 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.
MTWP models are for outdoor use with a temperature range of -31° F to +150°F (-35° C to +66°C) and maximum humidity of 98% ± 2% RH.
MTA-121575W-NW can be used outdoors with the IOB backbox.

3. Candela ratings in Table 1 are for clear lens. Derate approximately 25% for amber lens, 55% for green lens, 70% for blue lens and 80% for
red lens.

NOTE: THE MAXIMUM WIRE IMPEDENCE BETWEEN STROBES SHALL NOT EXCEED 35 OHMS. THE MAXIMUM NUMBER OF
STROBES ON A SINGLE NOTIFICATION APPLIANCE CIRCUIT SHALL NOT EXCEED 47.

WARNING: THE MULTITONE STROBE APPLIANCES 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, WHICH COULD RESULT IN PROPERTY DAMAGE
AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS.

WARNING: THESE APPLIANCES WERE TESTED TO THE OPERATING VOLTAGE LIMITS OF 16-33VDC FOR 24VDC MODELS
AND 8-17.5VDC FOR 12VDC MODELS USING FILTERED (DC) OR UNFILTERED FULL-WAVE-RECTIFIED (FWR). DO NOT APPLY
80% AND 110% OF THESE VOLTAGE VALUES FOR SYSTEM OPERATION.

Add strobe current from Table 3 to audible appliance current from Table 2 to obtain total current for each unit, if the strobe and audible are wired to
operate in unison on a single circuit.

WARNING: MAKE SURE THAT THE TOTAL RMS CURRENT REQUIRED BY ALL APPLIANCES THAT ARE CONNECTED TO
THE SYSTEM’S PRIMARY AND SECONDARY POWER SOURCES, NAC CIRCUITS, SM, DSM SYNC MODULES OR WHEELOCKS
POWER SUPPLIES 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 3 to determine the highest value of “RMS Current” for an individual strobe (across the expected
operating voltage range of the strobe), 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.

If the peak current exceeds the power supplies’ peak capacity, the output voltage provided by the power supplies may drop below the listed voltage
range of the appliances connected to the supply and the voltage may not recover in some types of power supplies. For example, an auxiliary power
supply that lacks filtering at its output stage (either via lack of capacitance and/or lack of battery backup across the output) may exhibit this
characteristic.

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

MT MULTITONE SETTINGS:

The Switch (SW1) of the Multitone Appliance, shown in Figure 1, is used to set the dBA sound output level and alarm tone. The factory settings are
shown below. Read these instructions carefully before changing any of these factory settings.

USE A SMALL SCREWDRIVER TO
CHANGE THE SWITCH POSITION.

STEP 1:

Set desired dBA sound output level as follows (Refer to Figure 1 and Table 4):

Multitone Strobe Appliances cannot be field set for input voltage. Multitone Strobe Appliances are field set for dBA sound output level by adjusting a
four position Switch (SW1) as shown in Table 4 and Figure 1. Use SW1 Position 1 to select the dBA sound output level.
