23. DOOR ENTRY PANEL INSTALLATION
The Advent XT2 warden call system can be enhanced to include a door entry facility with the addition of digital door
panels and door entry intercoms or door entry telephone handsets. Visitors can call residents direct from the door
panels or contact the
Manager by pressing the “Manager” button
, an electric lock release can be activated to allow
visitors access.
The “Trade” button
will allow access during 3 programmable time periods per
day and the “Code” button can be used
with a programmable 4-digit access code to allow access any time (or during 3 programmable periods) each day.
The door entry mode can be set to allow visitor-calls to residents 24 hours a day or to automatically transfer all calls to
the Manager during the evening and night. In addition, if a resident is away their calls can be temporarily transferred
to a neighbour or the Manager.
DIGITAL DOOR PANELS
Up to 16 door entry panels (P/No. ZXT950/951) can be connected to the Advent XT2 controller on a separate 6 pair
bus cable
. A local PSU is required at each door to provide power for the electric lock release. A “press to exit” button
and a
“
door status
”
contact can also be connected locally into each door panel.
The backbox should be orientated with the single
Earth stud in the top left-hand corner.
Do not cut a hole in the top face of the backbox for
cable entry - this may allow water to enter and
damage the electronic components or keypad.
Cable entry into the backbox should be through
any of the 20mm knockouts provided.
IMPORTANT
: the backbox and fascia must be
bonded to the Mains Earth terminal using a
minimum of 2.5 mm
2
cable.
INSTALLATION
The standard backbox is designed for flush mounting - a stainless surface cowling (P/No. HM1140) is available
separately. Do not cut a hole in the top face of the backbox for cable entry as this may allow water to enter and
damage the electronic components. The cut-out dimensions given below will allow the standard backbox to fit flush
into the wall with the bezel overlapping by approx. 14mm on all sides.

The backbox should be sealed with suitable mastic to prevent water ingress. The backbox and fascia must be bonded
to the Mains Earth terminal with a minimum of 2.5 mm
2
cable in line with current IEE regulations. The fascia is fixed by
6 off M5x12mm Allen key screws which require a 3mm Allen key tool.
A separate 6 pair door entry bus cable should be installed from the Advent XT2 controller common to all door panels,
or each door panel can be wired back separately to the XT2 controller. The lock PSU and associated wiring should be
local to each door panel.
FERRITE CORE
The door panel wiring must be looped through the
ferrite core inside the backbox.
This will suppress any voltage transients induced
on the wiring and greatly reduce the likelihood
of damage to the CPU.
