Model 5451EIS is an intrinsically safe rate of rise
detector with fixed temperature alarm. It uses stateof-the-art dual thermistor technology to provide
maximum sensitivity. This detector is designed to afford
open area protection and is for use in hazardous areas
where potentially explosive atmospheres are likely to
arise (confirm classification of equipment required with
your responsible authority). Model 5451EIS detectors
are designed to be used with compatible panels only.
Each detector has remote LED annunciator capability as
well as two LEDs to provide a local visual indication of
detector status. Once the detector senses a fire, it
latches in alarm and remains in this condition until it is
reset by a momentary power interruption.
