1. Scope

1.1 Product Overview

The SharpEye CCTV Model Flame Detector (20/20CTIN and 20/20CTIP) is a self-

contained, triple-spectrum, optical flame detector that incorporates a video color

camera. The detector's IR sensors and spectral band pass filters have been

selected to ensure the greatest degree of spectral matching to the radiant energy

emissions of fire and the lowest degree of matching to non-fire stimuli.

The color video camera enables the user to investigate the monitored area, to

identify the fire's source and location, and help select the best response to the

situation (activation of fire suppression means).

Configuration can be made to issue a live color video picture signal at all times, on

request or only when a fire is detected. Therefore, the detector is also useful for

standard CCTV purposes.

The front side of the detector is sealed to keep the electronic and sensor chamber

dry for longer life. The programmable functions are available through a RS 485

port used with a standard PC or by a Pocket PC and software supplied by

Spectrex.

The video signal output of the CCTV Model Flame Detector can be either NTSC or

PAL.

Refer to Manual TM 784050 for instructions to use the HOST software and to

change the required Functions.
