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.
