Overview

The leakproof, stand-alone, digital, electro-optical

FS7-2173-2RP flame detector, with pigtailed cable, is designed

for installation within wet benches and other equipment

containing combustible materials in semiconductor

manufacturing clean room environment. The alert criteria are

programmed for a 3.9 kW and alarm criteria are programmed

for 13 kW polypropylene pool fire. The detector housing is rated

IP67. dust tight, and watertight to 1 meter.

FS7-2173-2RP

Electro-Optical Flame Detector

The FS7-2173-2RP detector contains a multi-spectral sensor

array consisting of Wide Band IRTM, Near Band IRTM, and Visible

BandTM sensors. The detector is designed to see all types of

hydrocarbon and non-hydrocarbon fires, including

polypropylene and IPA fires. The detector is able to see a one

square foot heptane fire at half the stated sensitivity when the

fire is 60 degrees off-axis. The detector’s microcomputer, with

digital signal processing algorithms, continuously monitors its

circuitry and verifies proper operation. When a fire is detected,

the alert relay is activated at 3.9 kW and alarm at a 13 kW

polypropylene pool fire criteria. The detector has a non-latching

relay and automatically resets the fire signal relays after 5

seconds, once the fire self-extinguishes or is discharged.

The detector’s printed circuit board is housed in a

polypropylene water- and acid-proof (leakproof) heat-sealed

(IP67) enclosure.

FirePicTM

The FirePicTM feature provides digital spectral data information

facilitating analysis of the probable fire cause. This feature may

be used to prevent a subsequent, potentially damaging fires

from occurring. FirePic will store 6 fire events in the non

volatile digital memory, 8 seconds of pre-fire, actual detector

sensor spectral data, and the time and date for each event. The

stored data includes a graphical display of the relative spectral

intensities versus time preceding and during the fire event.
