Installation
The flexibility of the modular system
allows for simple installation of single
or multipoint gas detection systems.
Each point of detection requires the
installation of one sensor/transmitter
and one receiver module. The sensor/
transmitter is installed in the area to be
monitored and the receiver module can
be located up to 1000 feet away. A power
supply module, sufficient for use with
up to two receivers, is housed with the
Receivers in a NEMA 4X enclosure.
All enclosures are provided with knockouts
on all four sides to facilitate wiring using
the 1/2" FNPT (12.7 mm) conduit hubs
provided. Equally suitable for indoor or
outdoor applications, these NEMA 4Xrated
polystyrene enclosures are fitted
with a tough hinged polycarbonate
window for clear visibility of all indicators
and easy access to the control panel.
Included within the enclosure is a
piezoelectric horn to provide audible
local warning.
