    SigTEL 4-224 Line Controller - 4, 8 or 16

    Our SigTEL range comprises three wall-mounting master controllers (the ECU-4, ECU-8 and ECU-16 which can handle 4, 8 and 16 lines respectively). Typically located in a building's control room or fire services access point, they allow management and/or the fire services to communicate via a telephone-style handset with the system's 'outstations'. A controller without a handset (ECU-8NT) and a new 224 line desk controller (ECU-224) are also available.

    • ECU-4 can be connected to up to 4 outstations
    • ECU-8 can be connected to up to 8 outstations
    • ECU-16 can be connected to up to 16 outstations
    • Includes an attractive semi-recessed handset
    • Improved SigTEL networking capability allow systems of up to 224 lines to be created with optional/additional desk unit control
    • Backlit LCD and unique ‘auto-learn’ facility allows fast system set up.
