Installation
2.1
Location and Mounting
The Reader Expander is available as a PCB Only (Printed Circuit Board) or complete unit supplied with a metal
cabinet. We recommend that the cabinet is used wherever possible as this provides the best mounting and
installation solution as well as the required cable entry and termination space.
When installing the Reader Expander ensure that there is adequate clearance around all sides of the enclosure
and air flow to the vents of the enclosure are not restricted.
We recommend the Reader Expander is installed in a location that will facilitate easy access for wiring. We also
recommend that the Reader Expander is installed in electrical rooms, communication equipment rooms, closets
or in an accessible area of the ceiling.
1.
Insert the plastic stand-offs in to the locations to mount the PCB board.
2.
Calculate the location and position of the enclosure and mark the holes for the keyhole points in the top left
and right locations. This will allow you to screw in the screws and then hang the box on them adjusting the
location to suit.
3.
Ensure a solid fixing point and screw in the two screws. Before tightening the top screws insert the tamper
bracket in the slot provided on the right side of the enclosure.
4.
Fix the enclosure securely using the remaining mounting holes on the bottom left, right and centre of the
enclosure.
5.
Insert the PCB in to the enclosure and mount using the plastic standoffs inserted during step one.
i
Install the enclosure when the circuit board is NOT installed on the plastic stand-offs. This will reduce
the risk of damage caused by debris during the installation process.
2.2
Cabinet Tamper Switch
The enclosure tamper input signals to the monitoring station or remote computer that the Reader Expander
enclosure has been opened. The tamper input switch shall be mounted into the steel bracket provided and
connected to the tamper connection terminals as shown in the diagram below. The tamper input opens and
closes trouble zone RDxxx:01 on the Reader Expander.
