1INTRODUCTION
This document is the Folknoll Group Ltd 3-Zone Refuge EVC System Manual.
1.1 WHAT IS A DISABLED REFUGE EVC SYSTEM
A disabled refuge is a relatively safe area where people can gather in emergencies to await rescue. A
disabled refuge EVC is an emergency voice communication system that enables persons in a refuge to
communicate with building management in the event of an emergency. The purpose of the refuge
EVC is to help coordinate rescue by providing information, instruction and reassurance to refuge users.
1.2 FOLKNOLL 3-ZONE REFUGE EVC
For sites with 3 or less refuge areas, we offer our cost-effective 3-zone refuge EVC system. Installation
costs are reduced without compromising functionality by building the system controller and a battery
backed PSU into single steel enclosure.
1.1.1 Fire-Resistant Cabling
Terminals are provided within all equipment for cable termination and space is allowed for glanding
of larger fire-resistant cable types to comply with BS requirements.
1.1.2 Choice of Outstations
Any of our range of refuge outstations can be used in conjunction with our 3-zone refuge systems,
offering a range of vandal resistance, IP rating and DDA compatibility to suit your site.
1.1.3 3-Zone Master Station
Our 3-zone master station is a specially designed minimalist panel for our 3-zone EVC with individual
illuminated buttons for each outstation and input for remote enable.
1.1.4 3-Zone Controller with Battery Backed PSU
Our 3-zone controller and battery backed system PSU is built into a single steel enclosure. The system
is usually supplied with backup batteries capable of providing at least 24 hours of quiescent operation
and 30 minutes of alarm operation.
1.1.5 Audio Path Testing and Reporting
Folknoll Disabled Refuge EVC systems offer audio path monitoring and reporting. Audio tones are
generated by outstation speakers and detected by outstation microphones. This signal received is
verified to test the electrical and mechanical audio path. If a fault is detected it is reported on the
master station.
Audio path testing can be triggered by external devices e.g. timers or BMS. A fault output is available
to activate external devices or management systems.
1.1.6 Third Party Interfaces
Folknoll offer closing contact, serial and IP interfaces for integration with third-party systems, e.g.
BMS, alarm gathering, etc. helping to provide an integrated solution for your needs.

83-ZONE REFUGE EVC MAINTENANCE
This section gives a generic guide to the routine maintenance and testing of Folknoll Disabled Refuge
EVC systems. Local maintenance, testing and repair procedures should be implemented according to
local regulations, procedures, site conditions, risk assessment, and equipment installed.
Disabled Refuge EVC systems are usually only used in the event of an emergency. Faults and other
issues that develop may not be discovered until an emergency arises and the system is required. It is
important that routine maintenance and frequent testing is carried out to ensure that the system is
fully operational.
8.1 ROUTINE MAINTENANCE
Folknoll Disabled Refuge EVC systems require minimal maintenance. The systems are robustly
designed and have low wear as they are only used in emergency. The only parts to require regular
maintenance are the PSU standby batteries.
8.1.1 Standby Batteries
The PSU backup batteries should be replaced as the battery manufacturer advises or at least every 2
years.
8.2 VISUAL INSPECTION
Disabled Refuge EVC systems are usually located in ‘public’ areas and depending on location can be
open to abuse. The frequency of visual inspections should be determined by local regulations,
procedures, site conditions and risk assessment.
8.2.1 Outstations
System outstations should undergo frequent visual inspections to check:
•Outstations and signage are clearly visible and accessible by disabled persons, e.g. not hidden
by posters, or behind a large object such as a roll cage, located in a restricted area
•Outstations show no signs of physical damage e.g. water ingress, impact
•Outstations show no signs of other forms of abuse e.g. chewing gum in the microphone hole
•Outstations show no signs of any other forms of damage that might affect visibility, access or
operation
8.2.2 Master Station
The master station should undergo frequent visual inspections to check:
•The master station and any signage are clearly visible and accessible by disabled persons, e.g.
not hidden by posters, or behind a large object such as a roll cage, in a restricted area.
•The master station shows no signs of physical damage e.g. water ingress, impact
