ECU-4 SigTEL 4 Line Master Fire Telephone Control Panel
The ECU-4 is an ideal solution for fire telephone systems, disabled refuge emergency communication systems and stadium marshalling applications. It provides full duplex communication between the central operator and up to four handsfree disabled refuge outstations or fire telephone lines.
With the addition of the ECU-8S expansion panel, the total line capacity can be increased to 12 lines. Thanks to its networking capability, up to four control panels can be interconnected, allowing systems of up to 64 lines in total.
Its front door with LCD display and handset makes on-site use and system management easier. The auto-learn feature recognises connected field devices and allows straightforward commissioning. Semi-flush mounting can be achieved using the AFP385 bezel.
