The wiring schematic shown here for the electric locks is only an example. Refer to the wiringinstructions provided with your electric lock. When using an electric lock, select a device that meets the followingguidelines.R Electric lock connection terminal (L+/L-): 12 V DC, less than 1.5 AWire type and distance (between the monitor and the door station)When the multiple monitors are connected in a series, the maximum distance between the door station and the lastmonitor in the series ("Door station 2" and "Monitor 3" in the illustration above) is 100 m.From - To Max. distance Cable standard Cable type referenceDoor station - Monitor 50 m 0.5 mm² RVV4 (4-wire)100 m 0.75 mm²Electric lock - Door station 5 m 1.0 mm² RVV2 (2-wire)10 m 1.5 mm²Monitor - Monitor 50 m 0.5 mm² RVV6 (6-wire)100 m 0.75 mm²Installing multiple monitorsWhen installing multiple monitors, remove the jumpers (A) attached to the "TERMINATION (SHORT)" terminals ofthe monitors ("Monitor 1 and 2" in the illustration above).
