Use existing pictograms and emergency button on a lift equipped with OTIS REM5. OCC contains a circuit board and cabling for installation of SafeLine SL6, SL1 or MX2. The circuit board is easily installed on existing REM5 connectors and signals for emergency buttons and pictograms are connected to the emergency telephone.

If an SL6 is used, the bus signal is available through two RJ45 connectors on the OCC circuit board, enabling easy installation of a car station with a standard CAT5/6 network cable. A mounting plate is also available for replacing existing REM5 voice station with SLB-COP2 for use with SL6.
