Ceiling Loudspeakers
Designed to be aesthetically pleasing and acoustically
engineered for quality sound reproduction, the MC range
of loudspeakers are ideal for general public address,
background music and voice evacuation systems.
“FT” versions are supplied with firedomes which are fitted into
a ceiling prior to the driver assembly, giving the advantage of
hard wiring through 2 x 20mm and 1 x 25mm top gland entries
to a terminal block in the firedome. For ease of installation, the
units incorporate a user-friendly true first and second fit fixing
method and are supplied with a dual 100V/70V line transformer.
A convenient plug-in connector is provided for rapid second
stage installation.
The MC-FT range is supplied compliant to BS5839, part 8.
