Based around two core products, the TC4010 Remote Display Terminal (RDT) and the fully functional TC4020 Remote Control Terminal (RCT). Both remote terminals utilise the same graphical LCD user interface that can be found on the TC4000 series fire panels and are based upon the same advanced, flash based, microprocessor technology. All TC4000 series panels and remote terminals can communicate over the same 2-core network cable. Integral network interface incorporating a special screen termination to prevent mains frequency earth-loop currents flowing between network nodes. The ‘Ad-NeT' network operates as a true peer-to-peer system with full cross panel reporting, control and cause and effect functionality of up to 1000 zones. The display information is fully programmable by individual zone or sector and can display any combination of fires, faults, pre alarms or plant alarms. E.g. can display all information in its own sector, but only show fire signals from other sectors of a building. Both remote terminals incorporate buzzer mute, view, enable/disable and test facilities with dedicated system and navigation keys for simple user control. The RCT has additional sector based control keys for Evacuate, Silence, Resound and Reset, which allows other networked panels to selectively respond to controls as programmed. E.g. on a site with multiple buildings, a user may be allowed to silence and reset fires originating in their own building. Fires originating from other buildings are displayed but cannot be reset. Fully on-site programmable via on-board alphanumeric keypad or PC configuration tools. By using 'flash memory' and an advanced graphical display the remote terminals can be easily configured to operate in virtually any language, with any character set and allows for the installer's logo and company details to be displayed on the LCD display during normal operation.
