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 a number of other points throughout a building or building complex, particularly in a fire emergency situation. 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 diculty negotiating the evacuation
route.
• In buildings with phased evacuation and/or fire fighting lifts where it facilitates secure communications for building managers, fire wardens,
and attending fire ocers.
• At sports venues and similar complexes, where it will assist stewards in controlling the evacuation of the area in an emergency.
The Crisis Emergency Voice Communications System (EVCS) is designed to fully comply with BS5839 Part 9:2011 for use as a Fire Telephone
system, Disabled Refuge Call 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 by BS9999.
Disabled Refuge systems are required in buildings where the public or disabled sta gains access to any floor other than the ground floor using
lifts. Refuge areas are provided at each storey exit from each protected stairway.
2 Product Overview
The Crisis EVC System has been designed around a total network concept so all of the Crisis EVC panels have inbuilt networking.
The system comprises 3 types of panel; Crisis EVC Network Master Station, the Crisis EVC Master Station (2 to 8 lines) and a Crisis EVC Network
Expander Panel. For Crisis systems in excess of 8 lines a EVC Network Mater Station MS must be used as the master station, the system can then
be expanded by the use of an EVC Expander Panel or EVC Master Station in blocks of 8 lines up to a maximum system capacity of 512 lines.
Additional EVC Network Master Stations can be used wherever indication and control is required, i.e. fire control rooms and building reception.
These additional EVC Network Master Stations have the facility to filter the information that is displayed, so if there are several buildings with a
EVC Network Master Station in each building, the EVC Network Master Station can be configured to only display/answer EVCS calls from that
building. The system also has the ability for all calls to be displayed/answered on a particular EVC Network Master Station thus becoming the
overall site master. This display filter can also be applied to “Assist Call” indications so panels can be configured to only display/acknowledge calls
from “Assist Call” emergency assistance alarms. This display filtering works in exactly the same manner as for EVCS calls.
Each EVC Network Master Station can be configured so information displayed during daytime is distinct from information displayed during night
time, thus allowing separate locations to handle daytime operations and night-time operations. The day/night timing applies across the entire
network.
The Crisis EVC Network Master Stations are able to call individual outstations via a named directory list or by dialling the appropriate extension
number for the desired outstation. In addition to this it is possible to call from one EVC Network Master Station to another so communication
between master stations is possible and control can be transferred between master stations.
The wiring is a ring and spur topology with outstations being wired on radial spurs from any master station or system expander panel. The EVC
Network Expander and any EVC Network Master Station or EVC Master Station are wired in a ring network up to a maximum of 64. The EVC
Network Expander would typically be sited in convenient locations close to the outstations i.e. risers or stairwells resulting in short vertical wiring
runs. The EVC Master Station can be used to provide local control of up to 8 lines within a building this can then report back to a Crisis EVC
Network Master Station which can provide overall control of an entire site. In this way a very large system can be completed with a minimum of
cabling coming back the master station via the network ring.
Additionally the “Assist Call” emergency assistance alarm system can either be connected to the same line with an outstation, or connected
to a dedicated line. As each line is powered from the EVC Network Master Station or EVC Network Expander, the outstations and the “Assist
Call” emergency assistance alarm system do not require a separate power supply unit. This has the additional benefit of each line being fully
monitored and battery backed up.

3 Important Safety Information
This Equipment must only be installed and maintained by a suitably skilled and competent person.
This Equipment is defined as Class 1 in EN60065 (Low Voltage Directive) and must be EARTHED.
Caution: Indoor Use Only
Warning: Shock Hazard - Isolate Before Opening
Warning: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE
Warning: THIS UNIT MUST BE EARTHED
Warning: NO USER SERVICEABLE PARTS
Each Crisis EVC Network Master Station or EVC Network Expander Panel requires a 3A spur, returning to a breaker clearly marked “EVCS DO
NOT TURN OFF”.
If the Crisis EVC Network Master Station and the Crisis EVC Network Expander are distributed around a site, it is essential that both Crisis Stations
are on the same mains phase, as they are classified TEN 230V. Powering from dierent phases can mean a 440V potential can be present in a
Crisis EVC Station during a major fault incident.
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.

4 Installation
4.1 Connecting the Crisis EVC Network Expander
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.
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.
Figure 2: Crisis EVC Network Expander Internals
Prior to mounting the Crisis EVC Network Expander, it should be decided if the field wiring is to be run on the surface or concealed. There are 14
knockouts on the top and 2 slotted entries with a dedicated mains supply entry at the rear. If a knockout is removed by mistake, fill the hole with a
good quality cable gland.

Figure 3: Crisis EVC Network Expander Top Entries
Unused knockouts must be left unopened to comply with the Low Voltage Directive. Accidentally knocked out holes should be blanked o.
The Crisis EVC Network Expander weighs 5kg with batteries, so care should be taken to securely mount the Station on stud walling.
4.2 Planning the Wiring
All system wiring should be installed to meet the appropriate parts of BS5839 Part 9:2011 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.

4.3 Cable and Wiring Guidance
4.3.1 Fire Telephone System
Any system using Type A outstations must use enhanced grade cabling throughout for all wiring, including the mains supply to the Crisis EVC
Network Expander.
4.3.2 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; as long as 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.
4.3.3 Combined Systems
For systems containing Type A, Type B or Type C outstations, shared cable such as network cables must be enhanced grade.
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.
4.3.4 “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.
4.4 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.

4.4.2 Crisis EVC Network Master Station & Expander Panel - Ring Wiring
If more than 8 lines are required then an Expander Panel will be required in addition to the EVC Network Master Station, with the outstations
shared between both the EVC Network Master Station and the Expander Panel. The system has to be wired as a ring as shown in the schematic
below. This ensures that the loss of any single cable will not aect the operation of more than one outstation.

4.4.4 Mains Connection
Each Crisis EVC Network Master Station, EVC Network Expander Panel and EVC Master Station requires a 3A spur, returning to a breaker clearly
marked “EVCS DO NOT TURN OFF”.
If the Master Stations and Expander Panel are distributed around a site, it is essential that both panels are on the same mains phase, as they are
classified TEN 230V. Powering from dierent phases can mean a 440V potential can be present in a Station during a major fault incident.
4.5 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 Crisis EVC Network Expander requires one number 12V 7AH vent regulated sealed lead acid battery. The battery is not supplied with the Master
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.

4.6 Outstation Connections
The Crisis EVC Network Master Station and EVC Network Expander Panel are configured via the configuration spreadsheet contained on the
Micro SD Card supplied with the Master Station, for configuration see section 6.
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.

The “Assist Call” ACA kit comprises an Over Door Indicator, a Pull Cord, and a Cancel Plate. The above order is a typical order; with the Over Door
Indicator, Pull Cord and the Cancel Plate connected as shown, but the plates can be wired in any order as long as the EOL resistor goes into the
free terminal of the last plate.
4.6.4 Enable Switch Input
The Enable Switch Input is used for the remote enabling or disabling of panels, it connects to a spare line input in either a Crisis Master Station
or System Expander. A typical application would be a sports stadium which requires control to switch to the match control room during the event.
The input is monitored and expects a 470R resistor for activation, not supplied (a fire alarm manual call point may be used) The 10K EOL resistor is
as supplied with the panel.
4.7 Auxiliary Connections
Figure 10: Auxiliary Connections
The Crisis EVC Network Expander 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
7.7 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.
If the system is disabled, the master station can still make outgoing calls.
If this function is used, it only requires connection with one panel on the network. If the Enable Input is CLOSED on one panel, then all panels on
the network are CLOSED. To disable Type B outstations, then the Enable Input on all panels on the network must be OPEN.
4.8 Powering Up Procedure
Before powering up the EVC Network Expander, carefully check all internal wiring.
1. Apply mains power first.
2. Connect the battery using the battery leads supplied. Always connect the Positive (Red + ) terminal first before connecting the Negative
(Black - ) terminal.

Crisis EVC Network Expander Installation Guide
Page 15
www.eurofyre.co.uk
4.9 Powering Down Procedure
To power down the Crisis EVC Network Expander:
1. Disconnect the battery. Always disconnect the Negative (Black - ) terminal first, before disconnecting the Positive (Red + ) terminal.
2. Remove mains power.
5 Hardware Configuration Procedure
The Crisis range of panels has in-built networking. This is described in the product overview section. Install the additional panel/station as per the
relevant parts in the installation section 4.
Any panels on the network must be wired as a ring (see 4.4.1 and 4.4.2). This is due to the ability for outstations to be wired from any panel
therefore there is no loss of functionality due to cable faults as a ring provides redundancy.
Network connections used are Network Out and Network In, with Network In on one Station wired to Network Out on the other Station (A to A, B
to B, C to C, and D to D).
The default network address setting for the Crisis Network Expander is 2.
When adding a Network Expander, it must have a unique network address, and must be included in the site configuration file (see section 6 of the
Crisis EVC Network Master Station Installation Guide).
If the site configuration is not updated the panel will not be seen by the rest of the network and importantly any outstations connected to that
panel will not operate as they will not be seen by the rest of the network.

5.1 Network Expander Exchange PCB Dipswitch Settings
The Crisis network is formed from EVC Network Master Stations, Expander Panels, and EVC Master Stations. Each panel on the network has
to have a unique network address. This address is set by the dipswitches on the Exchange PCB. The address is a binary number given by the
positions of dip switches 1 to 6, with valid addresses lying between 1 and 64 inclusive.

will be illuminated, and the DC power indicator is extinguished. The PSU fault and General fault indicators will be illuminated. There should
be no line fault indicators illuminated.
• If there are no line faults present, the battery may be connected. The DC power indicator will be illuminated, and the PSU fault and General
fault indicators are extinguished when battery is connected.
• If there are any line fault indicators illuminated, then the field wiring should be checked prior to the battery being connected.
• Repeat the power up section for any additional Expander panels or additional EVC Master Stations.
• Upload the site configuration from the Micro SD Card (recommended) or using the menus.
• If device missing or network faults are reported address these before continuing. Once remedied re-upload the site configuration to ensure
all panels are programmed.
• Lift the master handset receiver and listen for a cadence tone.
• All outstations may be tested now, visit each outstation in turn and test that it is connected to the correct Master Station or Expander panel
and perform an intelligibility test. This test should be conducted when the building has normal background noise levels. The intelligibility test
requires two personnel.
• Where Assist Call is fitted, all pull cords in each circuit should be tested, acknowledged at the panel, cancelled at the call location and the
panel text checked. Ensure all controls and indicators operate correctly.
• When all outstation tests are complete, network cable checks should be performed to ascertain correct operation by unplugging network
cable to ensure the network is correctly fault monitoring and continues to work with a single cable fault.
• When complete the log may be retrieved from Micro SD Card, saved as a spreadsheet and kept for record purposes.
8 Maintenance
It is a requirement of BS 5839-9:2011 that a maintenance agreement be in place for the EVCS. The maintenance schedule should be as follows:
Frequency Test
Weekly Test a dierent outstation on the system each week and make a call to the control. Repeat each week until all outstations and
master stations are tested. Record these results in the site log. *If more than one master station is present alternate weekly.
Biannually Engineer call to check system operation, intelligibility, field strength of attached AFILS equipment and check battery health.
Record results and any variations into the site Log Book
Yearly Engineer call to check system operation perform 100% outstation and master station operation, field strength of attached AFILS
equipment and check battery health. Record results and any variations into the site Log Book
5 Yearly In addition to Yearly tests replace all batteries and record in Log Book.
