Honeywell FS7 Flame Detector

The Honeywell FS7 Flame Detector provides and intelligent two-stage response to semiconductor wet bench fires:

Stage 1: Alert.
This is the first-stage response to a small fire with a heat energy output of 3 kW (the equivalent of a 4-inch diameter polypropylene pool fire). This allows time for the fire to self-extinguish.

Stage 2: Alarm.
If the fire does not self-extinguish, and grows to the Factory Mutual specified heat energy threshold of 13 kW (the equivalent of an 8-inch diameter polypropylene pool fire), the second-stage response is activated.
