With the external alarm inputs it is possible to monitor the status of connected
devices, e.g. a UPS, via software. All alarm inputs are normally high (5 V) without
connection. The polarity (high/ low) can be set via the software at the Master Unit (for
details please see according software manual).
The device to be monitored must be connected so that the alarm contacts will be
closed in case of an alarm (I max = 8 mA). The alarm inputs are potential-free with
common ground.
Subminiature circular connectors series 712 with five and seven contacts, which are
contained in the alarm kit, can be ordered directly from the Binder Connector Group,
the manufacturer, or indirectly from Andrew Solutions (for ID No of the alarm kit see
).
