6.3.8 Fault alarm contact
For the activation of signal lamps or acoustic alarms and for notification of
higher level central control units, a channel can be parameterised as a fault
alarm contact.
The fault alarm contact is activated when:
The operating voltage fails (immediately)
The power unit fails (immediately)
There is no communication with the weather station (after 3 min.)
There is no communication with the control panel (after 40 min.)
When de-energised (idle state) and if there is a fault, the contact between C
and E is closed. When there is no fault, the relay pulls in and closes the con-
tact between C and
.
Each channel of the Wisotronic can be used as a fault alarm contact.
During commissioning, this channel must be created for the product fault
alarm contact.
The push button inputs of the channel parameterised as a fault alarm contact
are without function.
