TST stands for door control technology and describes a line division, which has been existing since the seventies.

Beside door control units also control units for barrier systems has been developed and today the TST-division is presenting itself as a complete product program of control units, impulse generators (induction loop detectors and micro wave motion detectors) and electronics for security devices.

Single devices or modules, standard devices or individual manufactured custom-made solutions: all products are harmonized to each other and especially made for door and barrier system.
