Description
Cerberus Pyrotronics’ series of Synchronous Electronic
Horn / Horn Strobes provide synchronous strobes with
temporal tone signals on one pair of wires. Two notification
output circuits are required: one non-silenceable - for
strobes and one for silenceable signals.
The new U-MHST series horn operates on a current of
23ma at 24Vdc, The audio portion of the signal provides a
temporal 95dB tone output. The U-MHST-1G mounts to a
single gang, the U-MHST horn or U-MHST horn/strobe are
either 1, 2 gang or 4” square mounting.
Cerberus Pyrotronics’ notification devices are designed with
the installer in mind. The U-MHST series devices are
constructed with all of the electronics in the housing and
not in the box. This design helps eliminate possible ground
faults from jamming wires and devices in the box. Units
are also available in two different colors, red or white.
The U-MHST/Strobe construction consists of a Xenon
flashtube with solid state circuitry for maximum reliability
and efficiency. Full range of candella series strobes have a
rounded dome shape made of clear Lexan ® . “FIRE” letters
are visible on the front mounting plate. The overall lens is
2.0” x 2 7/8” with a height of 1 3/8”.
U-MHST series synchronous strobes must be used with
either SCM-F or DSC (Dual Sync Control) modules.
To order a device in “white” use a “-W” at the end of the
model number (i.e., U-MHST-W).
