SigTEL ECU-4

The SigTEL ECU-4 4 Line Master Controller from SigNET is part of the SigTEL Compact 4-224 line emergency voice communication system is ideal for use in all disabled refuge emergency call point, fire telephone & stadium marshalling applications.

In disabled refuge applications, it allows people who cannot easily evacuate a building to communicate with a central control point whilst waiting for help during a fire or other emergency.

In fire telephone applications, it allows building management, the emergency services and fire marshals to communicate with each other before, during and after a fire.

The system is fully monitored, extremely cost-effective and meets and exceeds the requirements of BS 5839 part 9 when correctly installed.

  • Allows operators to communicate with up to 4 disabled refuge or fire telephone 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.
  • Can be semi-flush mounted using an EVC385 bezel.
  • Operation can be maintained for 24 hours (standby) and 3 hours (in use) using 2 x 12V 7 Ahr batteries.
  • Easily interfaced to NC951 accessible toilet alarms, PDA range hearing loop systems, strobes, CCTV activation relays, etc.

The SigTEL 4-224 line emergency voice communication system comprises three wall-mounting master controllers (the ECU-4, ECU-8 and the ECU-16 which can handle 4, 8 or 16 lines). Typically located in a building's control room or fire services access point, they allow emergency personnel to communicate via a telephone-style handset with the system's 'outstations'. A powerful networking facility allows up to 14 master controllers (any mix) to be interlinked meaning systems of up to 224 lines can easily be created.
