Installation
Important:
●
Review the section headed ‘Safety Information’ on
Page 31.
●
Ensure that ‘Design Considerations’ on
Page 7 have been understood.
●
Refer to the wiring diagrams from Page 27 onwards.
General
The major components of the system are fitted with high quality pluggable screw terminal
blocks. This enables all the connections to the system to be fully completed, whilst easily
isolating individual pieces of equipment during testing and commissioning.
Fitting the Control Unit
All of the equipment within the control unit box is mounted on a removable plate. It is
important that while the box is being drilled for cable-entry conduits and being secured to
the wall that the equipment is removed to prevent metal swarf from falling onto PCBs.
The mains connection can now be wired
as per the section entitled ‘Safety
Information’ on
Page 31 (Inside back page). Pay particular attention to earth
connections.
Installing the Battery
The battery (if required) should be installed only after all tests on the system have been
completed and any faults have been cleared. Take care not to inadvertently short out the
battery terminals as the available current (200A) may burn or overheat cables and other
metal objects. Once installed the battery is safe and fuse-protected. The battery sits on
the base of the control cabinet and is connected to the free spade connections already
provided. Ensure the correct polarity is observed; the red wire with the red spade terminal
goes to the battery positive terminal (also red).
Ensuring that the battery is fully charged may save test time.
Entrance
The panel should be mounted at an optimum height of 1.6 m, measured between the
ground and the top of the panel and is to be located on the wall adjacent to the main
entrance of the dwellings. With flush mounting panels it is advisable to apply mastic to the
top and side edges of the panel to prevent water ingress behind the panel, but not to the
bottom edge. On construction sites the panel must be protected from corrosive
substances such as ‘brick acid’. The panel should be cleaned only with a damp cloth
containing dilute detergent.
All connections to the entrance panel and doors are provided by the control PCB marked
'BSX2'; dual entrance models contain two controller PCBs, each of which is connected to
one entrance as shown in diagram 1 or diagram 4.
Up to 16 push-buttons are wired to the control PCB as shown on Diagram 2. The buttons
are wired with 1 common for each group of 8 buttons giving a maximum requirement of 10
cores.
If the panel has a Trades button fitted it is wired as a separate pair of connections to the
terminals marked 'Trade'.
