10 Alarms
The RBS 2207 can be connected to a maximum of 16 external alarms. The DF
is used for external alarm connection. Each alarm connection is provided with
overvoltage protection. (One OVP module protects two alarm connections.)
The alarm device can set the alarm by either an open or closed circuit.
The alarm device connected to the screw terminals should be isolated relay
contacts. A closed contact (logic zero) is required to be below 2 k
, and an
open contact (logic one) above 100 k
. The current through a closed 0
contact is 1.2 mA. The voltage between terminals with an open contact is
24 V DC. The external alarms are defined during installation either using the
Operation and Maintenance Terminal (OMT) or from the BSC.
