Therefore, it is extremely well suitable for the detection of fires which are difficult to detect with common smoke detectors - for example, alcoholic fires or gas flames. The detector is ideal for the following applications: • Pharmaceutical industry • Paint shops • Warehouses • Nuclear facilities • Tunnels three independent infrared sensors for different wavelengths and with an intelligent evaluation logic, the detector can safely distinguish between alarm situations and deceptive alarm

Due to its robust multi-wire screw terminals, the detectors can be wired with ease, thus achieving a secure and durable connection. The base provides the possibility to easily connect an external remote indicator, and has been designed for surface mounting in dry rooms. For special applications a range of accessories (for moist room, false cei- ling or flush installation) is available Specifications Ambient temperature -30°C to +70°C Relative humidity 0 - 95% (no condensation) Colour crea

The detector communicates with the RF Interfaces M500RFE-AS or M400RFE-AS via a secured radio protocol. The activated condition of the detector is optically indicated by an LED. The radio detector is especially suitable for areas, where cabling is impossible or uneconomical. 4 data channels in the frequency band 868MHz as well as 20 channels in the frequency band 434MHz are avai- Specifications Operating voltage Alarm temperature 58°C Range of radio transmission (free air) 300m Frequency

That way on the one hand the detector shows an especially high insensitiveness to unwanted alarms, on the other hand fires are recognised quickly and safely. The multi-criteria detector can operate in difficult fields of application, for instance • workshops – e.g., welding shops, paint shops • hotel rooms with steam formation in the bathroom • smoking areas in bars or restaurants • discotheques with fog generators • garages or loading ramps and is therefore suitable for virtually universal use.

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 per

The modern design of both measurement systems and the analysis of the parame- ters by means of a special algorithm allow to reliably evaluate the characteristics of fire. The sensitivity of the detector can be individually adjus- ted in 5 steps between 1.5%/m and 5.2%/m according to the application. Three steps have a fixed sensitivity, whereas two self-learning steps automatically adjust the sensitivity to short-term changes of the environmental conditions. Furthermore, the optical detection un

The modern design of the measurement chamber allows to reliably evaluate the characteristics of fire. An internal drift compensation adjusts the alarm threshold by continually evaluating the contamination of the detector. With that, the sensitivity of the detector is kept constant for a long time. Addressable conventional technology is used for alarm transmission to the fire detection control panel. The detector addressing can be achieved in 2 ways: • A detector with an Address Module NG58-1

It was developed to detect the characteristics of fire in a wide range of applications, and to avoid deceptive alarms. The modern design of both measurement systems and the analysis of the parameters by means of a special algorithm allow to reliably evaluate the characteristics of fire. This makes it an all-rounder that is used in virtually all fields of fire detection. An internal drift compensation adjusts the alarm threshold by continually evaluating the contamination of the detector. With t
