IS Optical Smoke Detector 2251EIS

ﬁ g. A

ﬁ g. C

The addressable Intrinsically Safe Optical Smoke Detec- tor 2251EIS (ﬁ g. A) uses the scattered light principle and was developed for the detection of smoke particles in hazardous areas. The modern design of the sensing chamber allows to reliably evaluate the characteristics of ﬁ re.

The proven ADM loop technology with System Sen- sor/200 protocol establishes a permanent communica- tion between the ﬁ re detection control panel and the detector. That ensures a periodical function testing of the detector. In the control panel all types of ﬁ res are detected by continuously comparing ﬁ re patterns.

Intelligent evaluation algorithms use the current condi- tion of the sensing chamber to predict the likely time

of the next maintenance. Thus the alarm threshold is automatically adjusted within the permissible range, de- pending on the contamination. With that, the constant response sensitivity of the detector is ensured for a long time.

The two LEDs with 360° visibility indicate the activated condition of the detector. The detector address is selec- ted with two decadic rotary switches, thus allowing to change the detector without additional tools.

A detector function test can be conveniently conducted using a magnet or test gas. The detector can be pro- tected against theft.
