Allgon Systems AB AR Repeaters This document describes installation, commissioning and the design of the Allgon AR Repeaters. Communication between Allgon AR repeaters and operators is carried out either by using Allgon OMT32 (Operation and Maintenance Terminal), or Allgon OMS (Operation and Maintenance System). OMT32 is described in the OMT32, User’s Manual. OMS is described in the Advanced Repeater OMS, User’s Manual.

Allgon Systems AB AR Repeaters Safety 1. Safety Any personnel involved in installation, operation or service of Allgon repeaters must understand and obey the following: • Allgon AR repeaters are designed to receive and amplify signals from one or more base stations and retransmit the signals to one or more mobile stations. Also, the repeaters are designed to receive signals from one or more mobile stations, amplify and retransmit to the base stations.
Allgon Systems AB AR Repeaters Safety • A lithium battery is permanently mounted on the CU and FON boards. Due to the risk of explosion, this battery must not be removed from the board. In case of battery malfunction, replace the entire board. The old board can be sent to Allgon for repair. • The optional FON board contains a class 1 laser transmitter that emits invisible laser radiation during operation. Avoid direct exposure from unconnected laser transmitter or fiber cord.
Allgon Systems AB AR Repeaters Safety Static Electricity Static electricity means no risk of personal injury but it can severely damage essential parts of the repeater, if not handled carefully. Parts on the printed circuit boards as well as other parts in the repeater are sensitive to electrostatic discharge. Never touch the printed circuit boards or uninsulated conductor surfaces unless absolutely necessary.
Allgon Systems AB AR Repeaters Installation 2. Installation Before installation, read carefully Chapter 1, Safety. Siting the Repeater Allgon repeaters are designed for outdoor usage. However, humidity and temperature changes may have affect on the reliability. A preferable site for the repeater is thus indoor, in a tempered and ventilated room.
Allgon Systems AB AR Repeaters Installation Dimensions and Weights The dimensions of the repeater, including the mounting bracket, is shown in Figure 2-1. The repeater chassis consists of two main parts, a cabinet in which the circuitry is housed, and a cover, which can be either a low cover or a high cover (see the figure) depending on the repeater type. Mounting bracket Cabinet Shelter Low cover High cover 520 (20.5") 110 (4.3") 530 (20.9") ALLGON 174 (6.9") 440 (17.3") 240 (9.4") 290 (11.

Allgon Systems AB AR Repeaters Installation Mounting The AR repeater is easy to mount using the provided mounting bracket, which has Ø14mm (9/16") holes for 10mm (3/8") or 12mm (1/2") fixing screws. Clamps with c-c measures of 90mm (3.5"), 135mm (5.3"), 144mm (5.7"), 205mm (8.1"), 250mm (9.8"), and 300mm (11.8") can be used as well. The vertical c-c measure for these are 411mm (16.2"). The mounting bracket is shown in the figure.

Allgon Systems AB AR Repeaters Installation Figure 2-6. Attaching the repeater to the bracket 2. After attaching the bracket, hang the repeater on the upper supports (see Figure 2-6) and use the screws for the lower ones. Tighten the upper and lower screws. There are locking cylinders that can be inserted and locked with a key after the lower screws have been tightened (see Figure 2-6). These prevents from unauthorized removal of the repeater. 3.

Allgon Systems AB AR Repeaters Installation Mains Breakdown Relay To be able to distinguish PSU faults from power failure, a mains breakdown relay can be used. The mains breakdown relay is not included in the repeater. So, it has to be mounted outside the repeater chassis. The relay intended for this purpose must fulfil the following specifications: Relay specification Closing time: Insulation coil/contact: Max. 30 milliseconds. Min. 4KV.
Allgon Systems AB AR Repeaters Installation Finishing the Installation Check all connections made. If a 24 Volt or 48 Volt power supply unit is to be used, then replace the PSU as described in the next section. When ready with the installation, commission the repeater as described in Chapter 4, Commissioning, in the AR Repeaters, User’s Manual. VD204 43/EN - Installation Guide Rev.

Allgon Systems AB AR Repeaters Installation Connection Ports The DIA distribution board provides most of the internal connection between the repeater units, and to external ports. Connectors involved in the installation are also located on the DIA board. These connectors are described below. A complete DIA board connector list is found in Chapter 5 of the AR Repeaters, User’s Manual. Figure 2-16 shows the location of the connection ports.
Allgon Systems AB AR Repeaters Installation P27 Auxiliary Port 1 8 Auxiliary port P27 is used to power the RCU, Remote Control Unit, for communication with the repeater. The connector is found on the DIA board to the left in the cabinet. P27 is an 8 pole, 1 line male connector. Pin 2 and 3 of the P27 port must always be interconnected to provide the CU and ALI boards with voltage supply. If there is no cable connected to the P27 port, pin 2 and 3 must be interconnected with a jumper.

Allgon Systems AB AR Repeaters Installation P28 - AI4 door switch alarm input 1 Normally, alarm input AI4 is used for repeater cover opening alarm EAL4, which is arranged using a door switch (optional). Because of that, AI4 and AIC are available also in the P28 connector, to which the door switch is connected. 3 The connector is found on the DIA board to the left in the cabinet. The EAL4 door switch alarm is activated 10 – 30 seconds after the cover has been opened.
Allgon Systems AB AR Repeaters Installation P34 Repeater to Repeater Link Port The P34 port is used for the R2R, Repeater to Repeater Link, which is an optional feature for the AR repeaters. This port is also used to interconnect the F2F, Fiber to Fiber Link feature, to the R2R net. The connector is found on the DIA board to the left in the cabinet. P34 is an 8 pole RJ45 modular female connector.
