Remote Control
–
see section 28 for details.
INSTALLATION
The Advent xt combined intercom unit should be wall mounted in the room most often used by the resident. Screw fix
the intercom rear securely to the wall using the 4 holes marked “A”
-
the 2 holes marked “B” can be used for an
embedded box. Ensure the case is not twisted as this may prevent the lid fitting correctly.
SYSTEM
NETWORK
TERMINATION
The network cable should loop-in and out of each combined intercom via the cable entry
channel
on the top or the square cut-out in the rear. Wherever possible avoid cable entry from below as this may interfere with
the operation of the emergency pullcord. The cable clips marked “C” can be used to retain spare cores and prevent
possible short circuits when the intercom front is fitted.
The network wiring is terminated on the interconnect board in the rear section of the Advent xt combined intercom as
shown above.
Ceiling pullcords, smoke detector, PIR and auxiliary input devices are connected the same as a standard intercom, see
section 14 of this manual or the Advent xt wiring diagram Drg No. ZXT100 sheet 5.
Before fitting the intercom front the “Address” and “Options Select” DIL switches must be set. The jumper links LK1 & LK2
must also be set in the correct position.
