Accessories

This appendix describes the accessories that can help you maximize fire detection with the
SharpEye IR3 flame detector:

D.1

Long Range IR3 Fire Simulator (Ref 6798433°

The SharpEye IR3 Long Range Fire Simulator 20/20-310 is designed specifically for use
with SharpEye IR3 flame detectors. The Fire Simulator emits IR radiation in a unique
sequential pattern corresponding to and recognizable by the IR3 detector as fire. This
allows the IR3 detectors to be tested under simulated fire conditions without the
associated risks of an open flame.

There is an optional beam collimator, model no. 20/20-190, specially designed for
extended test range.

D.1.1

Unpacking

Verify that you have received the following contents:

•

Delivery form

•

Fire Simulator with integral batteries

•

D.1.2

Operating Instructions

Warning

: Do not open the Fire Simulator to charge the batteries or for any other reason in

a hazardous area.

Caution

: The following test simulates a real fire condition and may activate the

extinguishing system or other alarms. If this is not desired, disconnect/inhibit them before
the test and reconnect after the simulation.
