Installation Guide
•
Never carry out insulation tests on cables connected to electronic equipment .
•
DO NOT OVER TIGHTEN TERMINAL CONNECTOR SCREWS
•
Always use the correct type of cables specifically designed for the operation of
fire detection and alarm circuits .
•
Always adhere to volt drop limitation when sizing cables .
•
Always observe polarity throughout . Non colour coded conductors should be
permanently identified .
•
Screen continuity must be maintained throughout the entire loop circuit including
at each junction point and at each device . Terminals are provided on each device to
facilitate this .
•
The screen should be earthed at the connection point provided at the panel and
not at any other point . Both the loop start and the loop end must be connected to
the appropriate earthing points .
•
Care must be taken to avoid connecting the screen to the earthed body of any
metal devices, enclosures or cable containment . The screen or drain wire of the
loop cables should not be considered as safety earth and therefore should not be
connected to terminals marked with the earth symbol, except at the panel, and
should not be insulated with green and yellow sleeving .
•
The panel utilises intelligent soft addressing technology to greatly simplify the
installation and commissioning processes . Once the system has been installed
and the loops wired to the panel with all devices fitted, the control panel will
automatically scan the detection loops on power up and allocate each device
with an address number corresponding with its position on the loop . This avoids
the traditional need for manual addressing of the system devices which is time
consuming and provides a potential for error . If no devices can be found the panel
will keep rebooting and performing an auto-learn until a device is found on a loop .
•
It is of vital importance that accurate details are kept of the exact wiring route in
order to determine which address has been allocated to each device .
