3. Connect external alarm sensors (burglary, fire, etc.) and other
external alarm equipment (optical or acoustic signal, etc.), if any.
Cables for this installation is taken through free strain relief
bushings on the bottom of the repeater, in the same way as the
mains cable and the antenna cables.
External alarm is connected to the P33 alarm port located to the left
in the cabinet (see Figure 3-7 on page 3-9). Use a 15 pole D-sub male
connector.
The P33 port is described on page 3-11.
This is a schematic figure.
The various RCU parts can
be integrated or configured
differently.
4. Connect the internal phone/modem unit for remote control of the
repeater, if any.
The modem and a power backup unit are integrated in an RCU,
Remote Control Unit, which is mounted downmost inside the cabinet,
in front of the PSU. The RCU is available in different types for
various systems, which is further detailed in the Optional section in
Chapter 13.
The modem is connected to the P32 modem port (RS-232, V.24
interface) on the repeater located to the left in the cabinet (see
Figure 3-7 on page 3-9).
The P32 port is described on page 3-11.
The mobile phone antenna is connected to the MS –20dB port on the
BS directional coupler (DC) located to the right in the cabinet
(DC/BS), provided that the phone and the repeater operate in the
same system.
If an RCU is used, this is powered by the P27 auxiliary port located
to the left in the cabinet (see Figure 3-7 on page 3-9). Pin 2 and 3 of
the P27 port are interconnected with a jumper if not used. This
jumper must be removed before plugging the RCU connector to P27.
If the RCU is removed, the jumper between pin 2 and 3 on the P27
port must be reconnected. Otherwise, the CU and ALI boards will
have no voltage supply. Do not connect the jumper to another position
than between pin 2 and 3 on the P27 port.
The P27 port is described on page 3-10.
5. Connect a telephone line for remote control of the repeater, if any.
The telephone line is connected to a modem, which is connected to
the P32 modem port on the repeater.
The P32 port is described on page 3-11.
Use a free strain relief bushing at the bottom of the repeater for the
external telephone line cable.
