8 Transmission
The RBS 2107 supports two transmission standards:
• T1 1.5 Mbit/s, 100
, with PCM synchronisation
• E1 2 Mbit/s, 75
, with PCM synchronisation
• E1 2 Mbit/s, 120 , with PCM synchronisation
9 External Alarms
The RBS 2107 supports a maximum of 16 external alarms. The external alarm
unit can set the alarm using either an open or a closed condition.
The alarm device connected to the screw terminals must be isolated by 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 at the installation by using the OMT, or from
the BSC using the remote OMT.
Note: An installed DC/DC converter is hard-coded to alarm input 16 in the
external alarm unit. Pin 16 is therefore unavailable.
Note: An installed smoke detector is hard-coded to alarm input 2 and 3 in the
external alarm unit. Pins 2 and 3 are therefore unavailable.
