ECU-8 SigTEL 8 Line Master Controller for Disabled Refuge & Fire Telephone Systems
The ECU-8 is an ideal solution for fire telephone systems, disabled refuge emergency voice communication systems and stadium marshalling applications. It enables the central operator to carry out full duplex communication with up to eight handsfree disabled refuge outstations or fire telephone lines.
Total line capacity can be increased to 16 by adding an ECU-8 expansion panel. Thanks to its networking capability, up to four control panels can be linked together, allowing systems with a total capacity of up to 32 lines.
Its front door with LCD display and handset makes on-site operation and management easy. The auto-learn function quickly recognises connected devices, enabling fast commissioning. Semi-flush mounting is also possible using the AFP385 bezel.
