Ionization Intrinsically Safe Detector 1151EISE

Ionization Intrinsically Safe Detector used in hazardous locations 1151EISE System Sensor

1151EISE - Ionization Intrinsically Safe Detector System Sensor

Intrinsically safe detectors are used in hazardous locations where explosive levels of gas or vapours are normally or potentially present. The 1151EIS circuit power levels is limited so the potential to ignite an explosive atmosphere is eliminated.
Model 1151EIS ionization smoke detector uses a state-of-the-art sensing chamber. This detector is designed to afford open area protection and is for use with compatible two-wire control panels only. Once the detector senses a fire, it latches in alarm and remains in this condition until it is reset by momentary power interruption.
1151EIS is equipped with two LEDs that provide a local, 360° visual indication of detector status. Remote LED annunciator capability is also included. The detectors can be tested by activating the internal reed switch with a test magnet.
