Produktübersicht
The analogue, line-shaped heat detection system Alarmline II is a flexible, long-lasting form of fire detection, suitable for use in confined spaces or harsh environmental conditions. The system consists of an evaluation unit that is PC-programmable and a sensor cable. The Alarmline II sensor cable is a four-conductor cable that senses temperature changes by continuously monitoring the resistance of the specially doped polymer insulation (NTC). An abnormal change in resistance along the sensor cable triggers either pre-alarm or alarm conditions in the evaluation unit. The Alarmline II evaluation unit ensures the monitoring of the Alarmline II sensor cable, the configuration of alarm and pre-alarm temperatures as well as the interfaces to the BMZ.
- For use in tunnels, parking garages, escalators, conveyor belts, cold storage, high-voltage and recycling systems, among others
- The pre-alarm and alarm temperatures are programmed using a laptop on which the programming software is installed
- Potential-free changeover contacts for pre-alarm and alarm, opto-isolated phototransistor as fault output
- Display alarm / pre-alarm red LED
- Yellow LED malfunction display
- Green LED power supply indicator
- Remote reset possible
- With cable break and short circuit monitoring
- Combined Max/Diff detector adjustable to response classes A1, A2, B, C and freely adjustable
- For connecting up to 500m of sensor cable
- Detects temperature excesses even over long distances
- Resistant to mechanical and chemical influences, corrosion, moisture, dust
- Chassis temperature alarm
- Connection to the Loop 3000 via IOM3311, see connection diagram 56567
- Termination unit for closing the end of the sensor cable is included
