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 mod ule
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 specificati ons,
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.

GUIDELINES

1. MOUNTING - CAMERA HOUSING

Caution: Install with the appropriate screws

or drywall anchors to suit the mounting

surface. Select a suitable location that is

protected from accidental damage or

tampering, and environmental conditions

that could exceed the camera’s general

specifications.

See page 32.

Caution: Ensure the selected location is

protected from falling objects, accidental

contact with moving objects, and

unintentional interference from personnel.

Follow all applicable building codes.
