ECU-16 SigTEL 16 Line System Controller
The ECU-16 is an ideal solution for fire telephone systems, disabled refuge emergency communication systems and stadium marshalling systems. It allows the central operator to communicate in full duplex mode with up to 16 handsfree disabled refuge outstations or fire telephone lines.
Thanks to its networking capability, up to 14 control panels can be interconnected, providing a total system capacity of up to 224 lines. Its front door with LCD display and handset makes on-site operation and system management much easier.
The auto-learn function quickly recognises connected field devices and allows fast and easy commissioning. Semi-flush mounting can also be achieved using the AFP385 bezel.
