1. Introduction
1.1 What is an Emergency Voice Communication System?
An Emergency Voice Communication System, or EVCS, is a system that allows voice communication in
either direction between a central control point and several other points throughout a building or
building complex, particularly in a fire or emergency. The control points, or outstations by which they
are more commonly referred, generally comprise of a Type A outstation, a Type B outstation, or a Type
C Combined Type outstation. “Assist Call” emergency assistance alarm systems can also be
incorporated into the EVCS.
EVCS is generally required in the following situations:
•In any building or sports or similar venue where there are disabled people, or people who may
have difficulty negotiating the evacuation route.
•In buildings with phased evacuation and/or firefighting lifts where it facilitates secure
communications for building managers, fire wardens, and attending fire officers.
•At sports venues and similar complexes, where it will assist stewards in controlling the
evacuation of the area in an emergency.
The Lexicomm ViLX-228S Emergency Voice Communications System (EVCS) is designed to fully comply
with BS 5839-9:2021 for use as a Fire Telephone system, Disabled Refuge system or as a combined
system when both Fire Telephones and Disabled Refuge Points are required.
1.2 Suitability
Fire telephone systems are recommended for all public buildings and multi-story buildings over four
floors that require phased evacuation as per BS 9999:2017.
Disabled Refuge systems are required in buildings where the public or staff gains access to any floor
other than the ground floor using lifts. A refuge is a relatively safe waiting area provided at each storey
exit from each protected stairway.
Refuge areas are not just for wheelchair users, they are for anyone who may need assistance i.e.
someone who’s immediate evacuation will impede the egress of others, a pregnant woman over 6
months term or persons with long term injuries, arthritis etc.
2. Product Overview
The Lexicomm EVCS, or ViLX-228S, comprises of a Master Station and one or more outstations.
Additionally, the “Assist Call” emergency assistance alarm system can either be connected to the same
line as a Type B outstation or connected to a dedicated line. Neither the outstations nor the “Assist
Call” emergency alarm system require a separate power supply unit as each line is powered from the
Master Station. This has the additional benefit of each line being fully monitored and battery backed up.
The ViLX-228S Master Station has been designed for radial star topology. In most cases this will reduce
the cable requirements for all ring-based systems. The topology consists of spurs formed of 1 off two
core 1.5mm CSA cables (soft skin enhanced up to 500m per leg, MICC 200m per leg) to each
outstation.

The ViLX-228S Master Station weighs 6kg with batteries, so care should be taken to securely mount the
Station on stud walling.
5.1 Connecting the ViLX-228S Master Station
To comply with EMC (Electro Magnetic Compatibility) regulations and to reduce the risk of electrical
interference in the system wiring, the use of fire-resistant screened cables is recommended throughout
the installation.
All wiring should come into the enclosure via the knockouts provided and be fixed tidily to the relevant
terminals.
Note that correct cable glanding is essential. Due regard should be paid to any system specifications
which demand a certain cable type, providing it meets the appropriate national wiring regulations.
5.2 Planning the Wiring
All system wiring should be installed to meet the appropriate parts of BS5839 Part9:2021 and BS 7671
(Wiring Regulations). Other national standards of installation should be adhered to where applicable.
Do not test wiring using an insulation tester (Megger) with any
equipment connected, as the 500 Volt test voltage will destroy
these devices.
You must observe local wiring regulations. Do not run SELV and LV cables in the same enclosure
without adequate insulation between them.
5.3 Cable and Wiring Guidance
5.3.1 Fire Telephone system
Any system for use as a fire telephone system should use Type A outstations and must use enhanced
grade cabling throughout for all wiring, including the mains supply to the ViLX-228S Master Station.
5.3.2 Disabled Refuge EVC System
For buildings less than 30m in height, or any building with sprinklers fitted, standard grade fire resistant
cable may be used to wire Type B outstation and the mains supply to the Master Controller if the
planned evacuation will be completed in 30 minutes.
If the building is over 30m in height without sprinklers, or where the evacuation will take place over
multiple stages exceeding 30 minutes, then enhanced grade cables must be used.
5.3.3 Combined Systems
Cabling to Type A or Type C outstations must be in enhanced grade fire resistant cabling.
Individual spurs to Type B outstations can be wired in standard grade fire resistant cabling in
accordance with the wiring guidelines already set out for disabled refuge systems.
5.3.4 “Assist Call”Emergency Assistance Alarm Systems
All installations must conform to Building Regulations Approved Document M. The “Assist Call”is wired
using 2 core cable, and the “Assist Call” plates can be wired in any order.
5.3.5 Cabling methods
There are 3 cabling methods available:
•Connection to a Type A or Type C outstation: use 2 core enhanced grade fire resistant cable
when extending a firefighting telephone system.
•Connection to a Type B outstation: use 2 core standard grade fire resistant cable when
extending a disabled refuge system.
•Connection to an “Assist Call” system on a dedicated line requires 2 core 1mm CSA or above
PVC sheathed.

Figure 5
Each ViLX-228S 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”.
5.5 Battery Information
In the event of mains failure BS 5839-9:2021requires battery backup for 24 hours standby and 3 hours
operation thereafter.
A ViLX-228S Master Station requires one number 12V 7AH valve regulated sealed lead acid battery.
The battery is not supplied with the ViLX-228S Master Station. Vox Ignis recommend a Yuassa NP7-12
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.

5.6 Outstation Connections
The ViLX-228S 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, and Type C outstations the end-of-line 10kΩresistor is not required as it is integral to the
product. For Type B 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 10kΩresistor should also be removed from
the accessory pack and connected to the last plate on the system.
5.6.1 Type A outstation
Figure 6
Note: The Earth screen should be sleeved and connected to the terminal block in the controller,
and the earth stud in the Type A outstation.
5.6.2 Type B outstation
Figure 7

Document ViOD00214/rev0/jk Page 10 of 20
Note: The Earth screen should be sleeved and connected to the terminal block in the controller,
and the earth connection in the metal back box (if a plastic back-box is used cut the earth back
and insulate at the outstation.)
5.6.3 ACA Accessible Toilet Kit
Figure 8
The ACA kit comprises an Over door Indicator, a pull cord and a cancel plate and they can be wired in
any order, the above is typically as installed, and runs Overdoor Plate, ceiling Pull and then the Cancel
plate, the EOL resistor goes in the free terminals of the last plate.
5.7 Auxiliary Connections
The ViLX-228S Master Station has three auxiliary connections:
Fault is a normally closed volt free relay (30V DC 1A) which
OPENS on any fault, including loss of power.
In Use is a normally open volt free relay (30V DC 1A) connection
which closes when any outstation is operated, see Remote Signal
Display section 7.5 switch settings for further information.
Enable is a normally CLOSED input and is required to operate the
system, this is often connected to the fire alarm system. If Jumper
J9 is in place, then no connection is required at the terminals. This
function only disables Type B outstations, with Type A outstations
and “Assist Call” emergency assistance alarm systems continuing to operate. Calls from Type B
outstations automatically “time out” after approximately 30 minutes. It is advised that this feature is
not used as the system should always be available, not just during an evacuation. If the feature is used,
then the mode LED illuminates yellow after 30 seconds to show that the system is disabled.
Note. If the system is disabled, the master station can still make outgoing calls.
5.8 Powering up procedure
To power up the ViLX-228S Master Station, carefully check all internal wiring before applying mains
power to the ViLX-228S Master Station. Once the ViLX-228S Master Station is powered, the battery can
be attached using the battery leads supplied. When attaching the battery, always attach the Positive
(Red+) terminal first.
5.9 Powering down procedure
To power down the ViLX-228S Master Station, first disconnect the battery. Always disconnect the
Negative (Black -) terminal first. Once the battery leads have been disconnected, then remove mains
power.
