2.2.4 Alarm input and output
Please read the following section carefully before using the contacts.
2.2.4.1
Alarm input
The alarm input is switched when the external signal is switched to ground (mode: NO). For this
purpose, use e.g. a relay or switch.
NO and NC modes are supported.
Note:
If you want to interconnect several
recorders, avoid direct series or parallel
connection and use separate relay switching
contacts for each.
