Use this product according to this instruction manual.
GENERAL:
The Multitone Strobe Appliances are UL Listed under Standard 1638 for Fire Protective Service, private mode and UL Standard 464
for Audible Signal Appliances. They are Listed for indoor/outdoor use, wall or ceiling mount, with the backbox specified in these
instructions (see Mounting Options). 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.
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 Information). All inputs are
polarized for compatibility with standard reverse polarity supervision of circuit wiring by a Fire Alarm Control Panel (FACP).

The UL Listed "Rated Voltage" range is 18-31VDC for MT-24-WM/WH/RH and 12VDC for MT-12-WH using either filtered (DC)
or unfiltered full-wave-rectified (FWR) voltage. 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 signaling device.
WARNING: ALTHOUGH UL TESTING HAS VERIFIED THAT THESE PRODUCTS FUNCTION EVEN AT 80% OF
THEIR MINIMUM RATING AND 110% OF THEIR MAXIMUM RATING, WHEELOCK STRONGLY RECOMMENDS
THAT THE VOLTAGE APPLIED TO THESE PRODUCTS BE WITHIN THEIR RATED VOLTAGE RANGE. THE
APPLICATION OF IMPROPER VOLTAGE MAY RESULT IN DEGRADED OPERATION OR DAMAGE TO THESE
PRODUCTS.

STEP 2: Set desired alarm tone as follows (refer to Figure 3 and Table 6). Multitone Strobe Appliances are field set for any one of eight alarm tones by setting a four-position switch (SW1) as shown in Figure 3 and Table 6. Use SW1 POS 2, 3, 4 to select the desired alarm tone. 1) Multitone Strobe models have in-out wiring Table 6: Switch Settings terminals that accept two #12 to #18 American... -
Page 6: Mounting Option
Although the limits shown for each mounting option comply with the National Electrical Code (NEC), Wheelock recommends use of the largest backbox option shown and the use of approved stranded field wires, whenever possible, to provide additional wiring room for easy installation and minimum stress on the product from wiring. -
Page 7: Mounting Procedures
2-gang by 3-1/2" inch minimum deep electrical box (Figure B). All models can also be surface mounted to Wheelock's model IOB backbox (Figure C or D) or to a 4" square backbox (model DBB or BB) with Wheelock's model ISP extender (Figure F and G). - Page 8 Wheelock. No part of the Multitone Strobe products shall be decompiled, disassembled or reverse engineered.
