The Raychem TraceTek TTM was essentially a cut down version of the TTB-MA utilising a Grey plastic enclosure rather than the metal enclosure of the TTB-MA.
TTM panels were used to monitor:
TT100 water detection sensing cable.
TT300 water/aqueous chemical sensing cable.
TT501 Hydrocarbon sensing cable.
The TTM alarm module provided both a visual and audible warning if there was either a leak or loss of system integrity, it was available in 3 variants which read in either Feet, Metres or zones.
The system can be supported but spare parts for the panel are no longer available.
