- Model 128 - Multi-Zone System



The 128 Multi-Zone System operates a network of leak detection cables and sensors up to a total of 128 zones. A zone can be a single point or many metres of detection cable and the whole network is continuously monitored for leaks and continuity. Zones are electrically isolated from each other and individually displayed so the system can accept and report any number of simultaneous or consecutive zone alarms. An alarm in one zone has no effect on the normal monitoring of its neighbours or the rest of the system.

The FLOODLINE™ 128 Multi-Zone System consists of a control unit with full text display and a base unit for connection of the sensor network. The control unit provides clear and easy to understand status and alarm information. Output relays are provided for connection to remote alarm, BMS etc. BMS connection can also be provided by RS232/RS485 communication. Leak detection is shown clearly as LEAK DETECTED. Sensor or cable damage or failure is shown as SHORT CIRCUIT or OPEN CIRCUIT.
