It is important to run an appropriate power cable to the reader that is capable of carrying a current of 1A.
A 5 metre length of 0.75 mm sq x 2 core cable is supplied with the reader. For longer runs it will be
necessary to increase the size of the cable as any voltage drop will reduce the read range. We recommend a
cable of 2.5 mm sq x 2 core cable for distances up to 100 m.
A data cable must be run from the control unit to the reader interface. The recommended cable for this is
Belden 9540; a 10 core overall screened cable with a maximum length of 100 metres. Spare cores should be
used to double up on the power wires (Red/Black) to the interface.
The reader requires a higher current (up to 1A) than can be supplied by the ACU reader port and so an
independent 12V DC power feed must be provided. As per the wiring diagram, the spare outputs on the
Paxton 2A boxed power supply can be used for this purpose.
Fitting
Determine the position of the reader and mark and drill holes for the ixing screws and cable access. Fix the
mounting plate to the post with the locating hooks at the top. (Fig 1)
Feed the cables for power and data through the mounting plate and into the rear section of the reader leaving
enough slack to allow easy connection to the circuit boards later in the installation.
Tighten the weatherproof cable glands at the rear of the reader. (Fig 2)
Hang the rear reader section on the mounting plate and secure with two screws. (Fig 3)
Complete the wiring of the reader as shown in this instruction.
Join the front section to the rear section with the Allen screws provided. (Fig 4)
It may be necessary to briely remove the reader from its mounting plate if access to the Allen screws is limited by
the post or wall.
The long range reader consists of a reader module mounted inside the front half of the housing and a hands free
interface mounted inside the rear half. An interconnect cable is supplied that connects the two sections together.
Two 5 metre cables for data and power are provided. These enter the module at the rear through two compression
glands. If longer cables are required, refer to the previous section for further details.
