DESCRIPTION
The EX72 Explosion Protected Camera has
been designed for surveillance applications in
hazardous areas. The camera’s ATEX-rated
housing consists of a heavy-duty aluminum
casting with a chemical resistant viewing
window. The housing is also NEMA rated for
watertight use.
The EX72 contains either the FMZ300 “Compact
Zoom Module” or the dual board Vari-Focal
Auto-Iris lens camera. The FMZ300 module
features Ex-View HAD performance with a total
zoom of 216x as well as an infrared cut filter for
true color and infrared performance.
A voltage regulator circuit allows for 12V dc or
24V ac operation, as well as a range in between.
It also provides protection from voltage surge,
transient spikes, and reverse voltage.
For additional information and specifications,
please contact your Bosch Security Systems
representative.

INITIAL PREPARATIONS
•The camera’s voltage regulator board
(VRB) accepts an input voltage of either
12V dc or 24V ac, and a range in-between,
from a regulated power supply.
•The VRB automatically switches between
ac or dc inputs, therefore no internal wiring
changes are necessary to accommodate
these input voltages.
•Determine the optimum location for the
camera.
Section 1: Mounting-Camera Housing.
•All cameras have been tested prior to
shipment.
