Mains Connection
Each ViLX-228 Master/Repeater Station requires a 3A spur, returning to a breaker clearly marked “EVCS
DO NOT TURN OFF”.
If the ViLX-228 Master Station and the ViLX-228 Repeater Station are distributed around a site, it is
essential that both ViLX-228 Stations are on the same mains phase, as they are classified TEN 230V.
Powering from different phases can mean a 440V potential can be present in a ViLX-228 Station during
a major fault incident.

Battery Information
In the event of mains failure BS5839 Part 9:2011 requires battery backup for 24 hours standby and 3
hours operation thereafter.
A ViLX-228 Master/Repeater Station requires one number 12V 7AH vent regulated sealed lead acid
battery. The battery is not supplied with the ViLX-228 Master/Repeater Station.
Safety Information:
Sealed Lead Acid batteries contain sulphuric acid which can cause burns if exposed to
the skin. The low internal resistance of these batteries mean large currents will flow if
they are accidentally short circuited causing burns and a risk of fire.
Exercise caution when handling batteries.
Power Up Procedure:
Always apply mains power before connecting batteries. When connecting batteries,
always connect the Positive (Red +) terminal first.
Power Down Procedure
Disconnect the batteries before removing the mains power. When disconnecting
batteries, always remove the Negative (Black –) terminal first.

Outstation Connections
The ViLX-228 Master Station is equipped with at least one number Dual line card. One outstation per
line output can be connected. If no outstation is connected to the line output then an end of line 10kΩ
resistor should be fitted. The dipswitch located on the rear of the door mounted Display PCB is used for
configuration see 6.1
The following devices are available on the system:
•
Type A (fixed phone)
•
Type B (hands-free refuge point)
•
Type C “Combi” (combined Type A and Type B)
•
Jack point
•
“Assist Call” emergency assistance alarm system
For Type A, Type B, and Type C outstations, the end-of-line 10kΩ resistor should be removed from the
accessory pack and connected to the end-of-line terminal in the outstation.
For Jack points and the “Assist Call” system, the end-of-line 10kΩ resistor should also be removed from
the accessory pack and connected to the last plate on the system.
