Retro-fitting Otis REM

We were asked to come up with products to replace “REM” that could utilise the existing wiring and fixings, and also carry out the BS EN81-28 functions, without deviating or changing the original design or compromising the “CE2 Standard” for the Otis lift.
Our product fits behind the “cop” on an adaptor plate so the existing ancillary rem units can be accommodated and the voice synthesizer will still work, we have a plug in loom to accommodate existing pictograms and we utilise wiring from the alarm push to activate our autodialler and two wires from the car ancillary unit to connect to the “rem” telephone line.
This system can be expanded to any number of units/out-stations, in fact our machine room station is specially designed to fit in the landing controller incorporated into the architrave.
This is a simple plug and play system that is inexpensive and easy to fit.
