Extended Coverage Alarm Terminal

OL-ECAT is a high-performance addressable alarm terminal with 7- or 12-inch touchscreen controller, designed for interfacing with acquisition modules manufactured by OmniLeak. The communication with these modules is based on a proprietary long-range failsafe bus. Both versions are offered in IP54/NEMA 3S water-resistant wall-mounted enclosures, and can be installed in technical rooms and other premises where dripping water might be potentially present. The primary use of OL-ECAT is to monitor up to four circuits with long detection strings for conductive liquids or hydrocarbons of up to 1200 m each. The communication frontend permits robust and reliable operation even in case of partial failure of the circuit of acquisition modules. Each individual acquisition module is connected to an independent sensor cable and the system provides true multi-leak capability. All compatible acquisition modules are powered by the terminal through the proprietary bus and the need of additional infrastructure is considerably reduced. The maximum distance covered with this wired layout (accumulated sensor and jumper cables) is in excess of 2 km. The optional loopback wiring increases the system reliability in case of cable breaks and shorts. This provides a redundancy architecture. Alarm threshold adjustment on each sensing cable installed is possible. 

 The intuitive password-protected user interface on the touch panel provides flexible configuration and adjustable alarm threshold. High-level interfacing to BMS/DCS/SCADA is implemented through Modbus RTU, Modbus TCP, email alerts and SNMP Traps. Configurable dry contacts (number 12) for general alarm, leak alarm, power failure and trouble are also available.
