Preface
The FACILA-system is designed with a focus on usability. A two-wiresystem that is not sensible to
polarity, guarantees a quick and easy installation.
The multi-use of our monitors ensures an answer for every installation. Call forwarding, videosur-
veillance, mobile forwarding, standard and panic-lock activations and controlling gate operators,
FACILA has quick solutions for every case.
This guide is a supplement to the manuals of the monitors, doorstations and accessories
and does not replace the actual manuals!

Notions
BUS system
A ‘BUS’ is a signalline which has multiple devices connnected parallel. The purpose is to diminish
the number of connections between devices. In a FACILA-BUS the data-, audio-, power- and vide-
osignals have been integrated on two wires. When a connected device on a BUS wants to commu-
nicate with another device on the same BUS, it can only do so when the signalline is not occupied.
The device will put the address of the device it searches on the BUS so that it is clear which device
is requested. Giving each device a correct address is therefore very important.
Model Master/Slave
In a Master/Slave setup one device controls all other. The Master receives the call from the
doorstations and redistributes the signals to possible Slave-monitors with the same address. An
installation has at least one Master-monitor.

The Master/Slave setup is default because it groupes several monitors to one address.
This makes it possible to have up to 4 monitors for each installation (1x Master and 3x Slaves).
