Master Station Quick Start Guide
Page 1 of 8
The LX228N master station is a ready out of the box EVC system suitable for standalone and
small 2 panel network applications up to 8 lines. It is very simple to install, requiring no set
up or software, and is compatible with Vox Ignis range of Type A, Type B, Type C outstations
and the Assist Call range of emergency assistance alarms.
This guide summarises applicable information from the full
manual, which is available by scanning this QR code.
Figure 1
1. Mounting Information
Master stations should be mounted in fire control rooms or next to the fire alarm panel at a
mounting height of between 1.4 and 1.5m above finished floor level to the centre of the
controls. Type A outstations (fire telephone) are generally fitted in fire-fighting lobbies and
fire and rescues access points at 1.3 to 1.4m above (FFL). Type B outstations are used in
disabled refuges at a mounting height of 0.9m to 1.2m (FFL). For Emergency assistance
alarms see ViLX-ACA datasheet.
2. Cable Information
Fire telephone systems utilise Type A outstations and must use enhanced grade fire resistant
cabling throughout for all wiring, including the mains supply to the master station. Max
distance using 1mm or 1.5mm cable is 500m from outstation to master station.
Disabled Refuge systems utilise Type B outstations, they are wired in standard or enhanced
grade fire resistant cabling Refer to BS 5839-9:2021 for full details.
Max distance using 1mm or 1.5mm cable is 500m from outstation to master station.
Network/Repeater systems are wired in standard or enhanced grade fire resistant cabling, 2 x
2 core loops 1mm or 1.5mm (2c Data,2c Audio) Refer to BS 5839-9:2021 for full details.
Emergency assistance alarms (Assist Call) for dedicated circuits use 1mm 2 core flex for
lengths of 500m from the master or security cable for shorter lengths from up to 50m for 2
cores up to 200m if 4 cores are twisted together. If sharing with a Type B use the same
grade of fire-resistant cable.
3. Important Safety Information
This Equipment must only be installed and maintained by a suitably skilled and competent
person.

Each ViLX-228N Master Station requires local isolation with verification as per the Electricity at
Work Regulations 1989, returning to a B6A breaker clearly marked “EMERGENCY VOICE
COMMUNICATION SYSTEM. DO NOT TURN OFF”.
4. Anti-static handling guidelines
Make sure that electrostatic handling precautions are taken immediately before handling PCBs
and other static sensitive components.
Before handling any static-sensitive items, operators should get rid of any electrostatic charge
by touching a sound safety earth. Always handle PCBs by their sides and avoid touching any
components.
5. Battery Information
In the event of mains failure BS 5839-9:2021 requires battery backup for 24 hours standby
and 3 hours operation thereafter.
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.
Battery leads should be removed by grasping the plastic battery
spade connector covers not the red and black wires as this can
cause premature failure of the lead.
A ViLX-228N Master Station requires one number 12V 7AH valve regulated sealed lead acid
battery. The battery is not supplied with the ViLX-228N Master Station. Vox Ignis
recommend a Yuasa NP7-12.

6. Installation
Use the 2.5mm AF Hex Key supplied to open the right-hand front cover.

Figure 4
Unused knockouts must be left unopened to comply with the Low Voltage Directive.
Accidentally knocked out holes should be blanked off.
The ViLX-228N Master Station weighs 6kg with batteries, so care should be taken to securely
mount the Station on stud walling.

6.1 Repeater/Network Wiring
The LX228N master station can be connected to another LX228N master station to form a
small network, maximum of 2 x panels using a maximum of 8 lines, split 8/0, 4/4 or 6/2
across the 2 x panels.
Figure 5
Or it can be connected to an LX228N-0 Repeater station. The number of cables and method
is the same. See Figure 6
The default network address for the 2 x panels is 1, they must share the same network
address in this example.
A LX228N master station can also form part of a Lexicomm Network system, please see the
full manual for details of wiring etc.

Note: Only connect the earth screens on the Net in cables, cut back and
insulate Net OUT earth screens.
6.2 Display PCB Dip switch Settings
The ViLX-228N Master Station has various site configurations which are configured using the
dipswitch located on the rear of the Display PCB.

7. Commissioning
The commissioning should be carried out by a competent person who has a basic knowledge
and understanding of the design and installation sections of BS 5839-9:2021 and has access
to the specification of the project.
1. All wiring should have been checked and be fault free and 10KΩ EOL resistor fitted.
The mains and battery can be connected- AC, DC and Mode LEDs should be green.
2. Connect EVC/ Assist Call wiring to the Line cards.
3. Perform intelligibility tests, visit each outstation in turn press call for a Type B or lift
the handset in a type A. A 2nd person is required to answer the call.
4. Where Assist Call is fitted, all pull cords in each circuit should be tested,
acknowledged at the panel, cancelled at the call location. Ensure all controls and
indicators operate correctly.

8.1 Receiving a call
One of the eight zone LEDs and the mode LED will flash red to indicate an incoming call.
Lift the Master handset receiver. The User LED will illuminate Red.
Press the corresponding zone button (indicated by the red flashing LED). This LED and the
User LED will change to flashing green to show that this line is now connected, and a
conversation can take place.

8.2 Making a call
To make a call, lift the Master handset receiver and the User LED will illuminate red.
Press the zone button for the required outstation. The corresponding zone LED will flash red.
When the outstation answers the call, the zone LED flashes green, the mode LED illuminates
red and the user flashes green to indicate this line is now connected and a conversation can
take place.
8.3 Ending a call
To end the call from the outstation, either replace the Type A receiver back on its hook or
press the call/cancel button for a Type B outstation.
To end a conversation from the ViLX-228N Master Station, replace the Master handset
receiver back on its hook.
Note: This will not end the call, only the conversation. The call MUST be ended at the
outstation.
8.4 Assist Call alarms Operation
When an “Assist Call” goes into alarm, the appropriate zone LED will flash blue, and a two-
tone buzzer sounds to indicate that an “Assist Call” alarm has been operated. To
acknowledge the alarm, press the corresponding zone button, and the blue LED will
illuminate continuously with an intermittent buzzer tone every 15 seconds. If after 2 minutes
the “Assist Call” alarm has not been cancelled, the buzzer will resound, and the LED will flash
blue.
8.5 Accepting Faults
To accept the fault, enter either the access level 2 (code: 1664) or access level 3 (code:
1812) menu, then press zone button 1.
8.6 Panel Indicator Test
To test the panel indicators, enter either the access level 2 (code: 1664) or access level 3
(code: 1812) menu, then press zone button 2.
All LEDs will illuminate in a predefined sequence, and the buzzer will sound.
Press zone button 8 or button 2 to stop the panel indicator test and to return to the menu
options.
