Notifier MT User Manual

GENERAL

Wheelock’s Series MT and MT Strobe Multitone electronic
appliances offer a choice of eight (8) nationally and in­ternationally recognized alerting sounds: Horn, Bell, March
Time Horn, Code-3 Tone, Code-3 Horn, Slow Whoop, Si­ren or Hi/Lo Tone. The Code-3 Horn and tone patterns
are engineered to comply with NFPA/ANSI Temporal Pat­tern specifications without requiring additional equipment.
With MT and MT Strobe appliances, one alarm appliance
meets most of your signaling needs. Strobe models can
be synchronized using the Wheelock SM, DSM Sync Mod­ules or a power supply equipped with Wheelock’s pat­ented Sync Protocol.

The MT Strobes are designed for ADA applications with
maximum performance, reliability and cost-effectiveness
while meeting or exceeding the latest requirements of
NFPA 72, ANSI 117.1, UFC and UL Standard 1971 as well
as meeting ADA requirements concerning photosensitive
epilepsy.

Each MT and MT Strobe appliance has two installer selec­tive sound output levels: STANDARD dBA and HIGH dBA.
Non-strobe versions provide selectable voltage capability
in one unit, 12VDC or 24VDC. Strobe versions are specific
for either 12VDC or 24VDC and all models may be used
with filtered or unfiltered (full-wave-rectified) input voltages.
Separate input terminals are available, shunt wires are
provided to enable both tone and strobe to operate simul­taneously from a single input.

The Series MT Multitone Strobe appliances are UL Listed
for indoor wall mount applications under Standard 1971
for Signaling Devices for the Hearing Impaired and under
Standard 464 for Audible Signaling Appliances.

FEATURES

• One alarm appliance with (8) eight selective signals
to provide superior sound penetration for various

ambient and wall conditions with two field selectable
sound output levels

GENERAL NOTES ON STROBES

• Strobes are designed to flash at 1 flash per second
minimum over their “Regulated Voltage Range”. Note
that NFPA-72 specifies a flash rate of 1 to 2 flashes

Note: If the strobe and audible operate on the
same circuit, add the strobe current from Table
2 to the audible current from Table 1. For Peak
and Inrush current across the listed voltage
range refer to Installation Instructions.

*Average RMS Current is per UL average RMS
method and Average Mean Current is per UL
average mean method. For rated In Rush and
Peak current across the UL listed voltage range
for both filtered DC and unfiltered VRMS (FWR),
see installation instructions.

NOTES on dBA/CURRENT RATINGS TABLES ABOVE: 1) Anechoic dBA is measured on axis in a non-reflective (free field) test
room using fast meter response. For peak dBA (measured with peak meter response), add 5 dBA to typical anechoic values shown
in tables above. 2) Reverberant dBA is a minimum UL rating based on sound power measurements in a reverberant test room.

*

This setting is acceptable only for general signaling (non-fire alarm) use. Use the “high” dBA setting

with this tone or use a different tone for public mode fire alarm service.
