5.10.4 Alarm output as relay action
The relay outputs of the IQ S ENSOR N ET can be configured so a relay
action is triggered when an alarm event occurs (Open or Close). For
this the Alarm contact function must be set for the relay output in the
Settings of outputs and links.
The Alarm contact function is only available for relays that are not
linked with a sensor. If necessary, an existing link must be erased. For
details please refer to the operating manual of the output module.
5.10.5 Alarm message as an SMS
All alarm messages can be sent as SMS via a GSM modem. The same
information that is output on the display is transmitted when doing so.
Details of how to connect the IQ S
ENSOR N ET to a GSM modem are
given in the operating manual "Remote connection to the
IQ S
ENSOR N ET 2020 XT USB".
Caution
For critical alarm events take into account that - due to radio
transmission - SMS messages may possibly be received delayed.
