What sort of PCC transmitters exist?
The simplest transmitters are small units which will fit into standard 2×4 wall boxes (TK124, TK184) which have a keypad for manual operation. There are also small, 6-address interface transmitters (TB134). ACT also manufactures very specialized units for hotel/motel control (TD140), RS232 interface transmitters (TI103) and 64 input, interface transmitters (TI100). All newly designed ACT transmitters offer true 2-way communications capability (see ACT’s A10 overview document for more information). Other new transmitters are planned for release in the future.
