LumaSense supplies a 6-pin DIN plug (male) with a locking collar
JP0600 for connecting external alarm devices to the alarm relay.
Caution:
The DC voltage across the relay contacts must not exceed 25V. The
potential on the relay contacts must not be more than 25VDC above
chassis potential, as this will cause an excessive leakage current. The
current through the contacts must not exceed 100mA. AC voltages
must not be connected to the Alarm Relay socket.
