DISCOVERY 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 patented 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.
