Current Building Regulations insist all new non-domestic buildings
with more than one storey provide ‘refuge’ areas – relatively
safe places where people who cannot easily use fire escapes and evacuation
lifts can call for assistance and wait until help arrives. Simple,
effective two-way communication in these areas is essential, firstly
to assist rescue
teams in determining where assistance is required
and secondly to reassure people help is on the way.
C-TEC’s SigTEL Emergency Voice Communication (EVC) System has
been specifically designed to meet the rising demand for fully compliant
BS 5839 Part 9 disabled refuge systems.
comprises two wall-mounting master controllers (the ECU-4,
pictured above right, and ECU-8 which can handle 4 and 8 lines
respectively) and an eight
line expansion unit, the ECU-8S.
Typically located in a building’s
control room or fire services access point, the ECU-4 and ECU-8
and/or the fire services to communicate via a telephone-style
handset with the system’s ‘outstations’.Two
types of outstation are available (Type A and Type B).
Disabled refuge systems use ‘Type
B’ intercom style outstations. Our EVC302GF Type B
outstation offers true hands-free duplex speech and allows
anyone in a refuge area to communicate with building control
at the touch of a button. Attractively finished in green
steel, it includes connections for an optional induction
loop system for the hard of hearing and a general-purpose
relay output that closes on activation of the unit. In addition
to our EVC302GF flush outstation, surface, weatherproof and
stainless steel versions are also available.
Fire telephone and stadium
marshal systems use ‘Type A’ telephone-style
outstations. Our EVC301RPO outstation comprises a telephone
handset in a push-to-open red steel cabinet. It is typically
located at entrances and fire-fighting lobbies to allow
fire marshals to communicate with building control during
an emergency. Its housing has openings to allow its phone
to be heard and an optional flush mount bezel is available.
Both types of outstation connect
to SigTEL’s central control equipment using two cores
of 1.5mm sq. enhanced fire rated cable.
