The Raychem TraceTek TTG panel was available in 4, 8 and 12 zone variants. Each zone was capable of monitoring up to 30 Metres of either:
TT100 or TT1000 water detection sensing cable.
TT300 or TT3000 water/aqueous chemical sensing cable.
TT501 or TT5000 Hydrocarbon sensing cable.
The panel had 2 sets of clean relay contacts for Leak and a further 2 sets for fault which was common to all zones.
The system can be supported but spare parts for the panel are no longer available.
