Options AR Standard Repeater
4-12 044-05250 Rev A
The RCU is connected to P130 on either an RCI or FON. A jumper is required between pins 1
and 2 on the RCI if the P130 cable connector is disconnected. If a main power failure occurs,
the unit has a battery with enough capacity for sending a number of alarms.
Previous RCU versions have been replaced by the current type. The repeaters are
compatible with the previous version. Differences apply to the connections of the previous
version where data was transferred between the repeater and the RCU via the P32 modem
port on the DIA and was powered via the P27 auxiliary port on the DIA.
RCU for Radio Communication
The RCU antenna for a radio modem is connected to the BS antenna via the uplink DC,
provided the RCU and the repeater operate in the same cell system. Otherwise, the modem
must have a separate antenna. Data is transferred between the repeater and the RCU via the
P130 modem port on the RCI or FON. The RCU is also powered via the same port and has a
battery with enough capacity to send a number of alarms if a main power failure occurs.
RCU for Telephone Line Communication
The land line version uses a telephone line connected to a terminal block on the RCU. A free
strain relief bushing at the bottom of the repeater is used for the external telephone line cable.
