Section A.5.4 RS-485 socket (unit rear), page36

.In this configuration, you always should connect the NurseCall Main Unit first. The NurseCall NC8 Relay Units must then be connected to the RS485-bus one by one, not at the same time.Relay outputIn the same connector, a potential free contact is available. It is a low current switching contact. The relay (potential free, switching power max. 48 V / 0.5 A) is activated at a call for help, call for assistance or fire alarm. This relay can be set as closing or switching contact (cycle of 10 seconds on / 10 seconds off). This feature can be used to drive a signal lamp for example.For connector wiring, see
