Anleitung Zusammenfassung


c IS Optical Smoke Detector 2251EIS The addressable Intrinsically Safe Optical Smoke Detector 2251EIS (fig. 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 fire. The proven ADM loop technology with System Sensor/200 protocol establishes a permanent communication between the fire detection control panel and the detector. That ensures a periodical function testing of the detector. In the control panel all types of fires are detected by continuously comparing fire patterns. Intelligent evaluation algorithms use the current condition of the sensing chamber to predict the likely time of the next maintenance. Thus the alarm threshold is automatically adjusted within the permissible range, depending 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 selected 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 protected against theft.

B) is used for intrinsi- detectors in hazardous areas. Due to the galvanic isola-cally safe electric circuits. The built-in zener barrier and tion, the earth leakage monitoring can remain activated the safe galvanic isolation allow the connecton of fire in the fire detection control panel.

C) serves for the design of an intrinsically safe electric circuit in ADM loop technology. It allows the bidirectional data traffic between fire detection control panel and fire detectors in hazardous areas via an ADM loop with System Sen- sor/200 protocol. The interface is always used together with the Safety Barrier Y72221. The Surface Mounting Box SMB500 is required for mounting the protocol interface.
