wheelock MT Service Manual

FIRE ALARM SYSTEMS

Description:

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. With MT and MT Strobe
appliances, one alarm appliance meets most of your
signaling needs. Strobe models can be synchronized
using the Wheelock SM or DSM sync modules.

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, filtered
or FWR. Strobe versions are specific for either 12VDC
or 24VDC and 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 Multitone Strobe appliances are ULC Listed under
Standard CAN/ULC-S526-02 for Visual Signaling
Appliances and Standard CAN/ULC-S525-99 for Audible
Signal Appliances, and use a Xenon flashtube with solid
state circuitry enclosed in a rugged Lexan ® lens to
provide maximum reliability for effective visible signaling.

Note: If the strobe and audible operate on
the same circuit, add the strobe current
from T able 2 to the audible current from
T able 1.

For Peak and Inrush current across the
listed voltage range refer to Installation
Instructions.

CAUTION: 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.

WARNING: FOR ULC VERSIONS THESE APPLIANCES
WERE TESTED TO THE OPERA TING VOLT AGE OF
