For the function person alarm the input is activated via a signal cable that is connected to the light
switch in the station and starts an internal timer which after a set time activates a relay output. This

operator time is finished and has to be prolonged. If this is not done a person alarm will be sent . To
avoid that this happens the light switch has to be turned off and on.

sensor in the door and starts an internal timer which is set to after a certain set time activates a relay.
