1 Regulations
Operator Instructions
Disabled refuge systems are called for by DETR Approved document B (Fire safety) volume 2, section 4, Design for vertical escape and BS 5588 Fire precautions in the design, construction and use of buildings, Part 8, Code of practice for means of escape for disabled people.
Fire telephone systems for buildings are called for by BS 5588 Fire precautions in the design, construction and use of buildings Part 5; Code of practice for firefighting stairs and lifts, Part 10; Code of practice for shopping complexes and Part 11; Code of practice for shops, offices, industrial, storage and other similar buildings.
Fire telephone systems for sports venues are called for by the Guide to safety at sports grounds.
The installation of EVCS is covered by BS 5839-9 Fire detection and fire alarm systems for buildings
– Part 9:
Code of practice for the design, installation, commissioning and maintenance of emergency voice communication systems.
2 Safety
The EVCS is safe to operate provided it has been installed in compliance with the manufacturer’s instructions and used in accordance with this instruction.
DO NOT open the control enclosures as mains voltages are present inside. There is no need to open these enclosures except to carry out maintenance, or remedial work. Such work must be carried out by competent service personnel who are fully conversant with the installation manual for this product.
If equipment is damaged in any way, advise the person responsible for the EVCS at the site.
Regular servicing of the EVCS is required by BS 5839-9, by a competent organisation on a continuous maintenance contract. A fully itemised report of the status of the installation should be obtained at least once a year.
Management of the site is required by law (The Regulatory Reform (Fire Safety) Order 2005) to appoint a responsible person to ensure the EVCS (and other safety systems) remains operational.
3 System Overview
The EVCS provides reliable two-way communication between a permanently manned control room and key points on the site in a fire emergency. The EVCS comprises of fire telephone and/or disabled refuge systems.
Fire telephone systems are for use by trained people as part of the fire safety procedures at the site. Disabled refuge systems are for use by untrained people communicating with a trained Operator.
The two systems differ from a standard telephone or intercom system in the following ways:
Outstations do not have to dial the MCU, they call the MCU as soon as their handsets are picked up (at
Type A outstations), or the
‘Push to Call or Answer’ button is pressed (at Type B outstations)
Outstations cannot call other outstations
Type A (fire telephone) outstations may be in locked housings to prevent unauthorised access
The EVCS operates from mains and has battery back-up in case of mains failure so that it is always available
If there is a fault, a buzzer sounds intermittently at an MCU. Details of the problem are shown on the display. If the fault is not rectified the fault buzzer resounds after a period of 6 hours.
Note: The system also has a disabled persons toilet alarm (DPTA) interface which is a secondary function to the primary purpose of the EVCS.
4 Disabling the System
If an MCU is installed in a public area, the system may be disabled to prevent unauthorized use. If this is the case, the system will be enabled either, automatically when the fire alarm operates, or manually by operation of a breakglass call-point, or similar control. When disabled, the EVCS continues to check for faults but the MCU are suppressed from making, or receiving calls until an external trigger is applied.

9 Handling Calls at the MCU
Note: This section applies to both a non-networked MCU and the master MCU on a networked system. Additional call handling facilities are available for a networked system, see section 13.
9.1 To answer a call
When an extension calls in to the MCU, the ringer sounds and the display’s red backlight flashes.
The
MCU’s display shows the name of the calling extension (or networked MCU), see examples below.

Note: denotes MCU and is only seen on a networked system.
Lift the
MCU’s handset and press CALL / ACCEPT button to answer the call. If necessary, press ▲ and ▼ to highlight the extension you want to talk to and press CALL / ACCEPT button to answer the call.
The display’s red backlight returns to normal.
The symbol ( or or or wc
) will be reversed (i.e. or or or wc
) meaning you are connected to that outstation.
9.2 To end a call
Hang up the MCU’s handset or press HOLD button to end the call.
9.3 Ending one call and answering another
If another call comes in whilst you are talking to an extension, the MCU will not ring, but the display indicates the name of the calling extension and the display’s red backlight flashes. See typical display, right.

Operator Instructions
9.4 Conference calls
If you are already talking to one extension and another extension calls, you can talk to both at once by selecting the new call without ending the original call. No more than three outstations/MCU should be involved in a conference call as audio quality is reduced.
9.5 To call an extension
Lift the MCU
’s handset. If there have been recent calls, the recent calls list is displayed otherwise, the full directory is shown. If there have been recent calls, you can toggle between recent calls and full directory by pressing
DIRECTORY button. Press
▲ and ▼ to highlight the extension you want to talk to then press CALL / ACCEPT button to call.
To clear the recent calls list, see section 12.1.
9.6 Auto-answer feature
The EVCS can be set up with an Auto-Answer feature enabled. Normally, this feature is not enabled but can be programmed by a system engineer. When enabled, the MCU automatically answers an incoming call when its handset is picked up, rather than the Operator picking up the handset and manually selecting the extension of the incoming call before answering.
Note: If there are multiple incoming calls, there is less control for an Operator to manually select which call to answer. As a rule, when Auto-Answer is enabled, the lowest system numbered extension is answered first.
To answer a call - auto-answer enabled
When there is an incoming call, lift the
MCU’s handset. The call is automatically answered. If another extension calls into the MCU and requires answering, place the handset back on-hook to end the first call and wait for the MCU to start ringing again. When it does ring, lift the handset and the next extension calling in is automatically answered.
To end a call - auto-answer enabled
To end a call, hang up the
MCU’s handset.
Alternatively, if HOLD button is pressed you have the option of selecting an extension to ring.
To call an extension - auto-answer enabled
This is the same procedure as described in section 9.5.
10 Making a Call from an Outstation
There is no need to dial from an outstation as the system automatically calls the Operator at the MCU.
At Type A outstations, lift the handset and a double ‘beep-beep’ ringing tone sounds in the earpiece.
At Type B outstations, press the
‘Push to Call or Answer’ button – a double ‘beep-beep’ ringing tone sounds in the loudspeaker and the Call in Progress indicator is lit steady.
At the MCU the ringer sounds and the Operator can choose to answer.
If the Operator is talking to another outstation, an engaged tone (continuous short pips) sounds at the outstation’s earpiece. The Operator knows there is a call, so stay on the line until it is answered.
11 Answering a Call at an Outstation
When the Operator at the MCU calls an outstation, a ringing tone is heard at the outstation. At the outstation, either lift the handset (at Type A outstations) or press
‘Push to Call or Answer’ button (at Type B outstations).

14 Off-Hook Detection
The EVCS has enhanced features to detect off-hook handsets and jammed buttons at outstations.
Off-hook detection (at Type A outstations): Scenario: A call has been made from a Type A outstation, the call has been answered and ended at the MCU but the handset at the outstation has been left offhook for longer than 2 minutes.
Jammed button detection (at Type B outstations): Scenario: A call has been made from a Type B outstation, the call has been answered and ended at the MCU but the button at the outstation has pressed / jammed for longer than 2 minutes.
For the two scenarios above, after the 2 minutes have elapsed, the fault buzzer at the MCU sounds, the General
Fault indicator lights and a fault message is displayed, see example below left. Press CALL / ACCEPT button at the MCU and details of the off-hook or jammed button extension is displayed, see example below right.

15 Monitoring Toilet Alarms
The monitoring of disabled persons toilet alarm (DPTA) is a secondary function to the primary purpose of the
EVCS. If the site has toilet alarms AND they are connected into the EVCS, then active toilet alarms will be displayed at the MCU. As toilet alarm monitoring is a secondary function, any toilet alarm will be suppressed from being displayed if there are any calls from/to the outstations. At the end of outstation calls, the activated toilet alarm calls will be displayed.
Toilet alarms received at the MCU can only be reset at the alarm point and cannot be reset at the MCU. Someone has to physically go to the location of the toilet alarm in order to reset it.
On the MCU’s display, toilet alarms are denoted by the graphic symbol ‘ wc’
which is reversed
‘ wc
’ when active. This symbol will never appear in the same list as outstations and pressing the DIRECTORY button (with the handset on-hook) will not show toilet alarms because you cannot call them. Similarly, toilet alarms will not appear in the Recent Calls list.
W C A l a r m s wc :
DPTA No.1 wc
DPTA No. 2
When a toilet alarm is activated, its name is displayed at the MCU. The buzzer operates continuously (to distinguish it from fault and EVCS operation). The buzzer can be temporarily silenced but will restart if the toilet alarm is not reset within 5 minutes. When the toilet alarm is cleared the MCU automatically reverts to normal mode.
