XP95/Discovery Detector Base with Xpert
Card
All detectors in the Discovery range fit into XP95 mounting bases. An
earth connection is not required for either safety or correct operation
of detectors. The ground (earth) terminal is isolated and is provided
for tidy termination of grounded conductors or cable screens and to
maintain earth continuity where necessary. All terminals are marked
according to their function.
Bases have a wide interior diameter for ease of access to cables and terminals and there are two slots for
fixing screws. The slots enable two fixing screws to be located at a spacing of 51 to 69mm.
Detectors fit into bases one way only, without snagging, and require clockwise rotation without push force to
be plugged in.
Universal address cards, known as XPERT cards, are supplied with all bases. Consult the coding guide in
the installation instructions to determine which pips are to be removed from the card to give the correct
address. Lay the card on a flat surface, pips down, insert a screwdriver into the slot on the reverse of the pip
to be removed and give a firm twist.
When the card is coded, insert it into the slot in the side of the appropriate base, making sure that the card
locks itself into place. As a detector is inserted into the base, the remaining pips operate the address buttons
on the detector and the detector electronics reads the address.
The bases are 100mm diameter and have five terminals:
