Voice Alarm Systems for Corporate & Public sectors - Middlesex, London UK 


Voice Alarm system installations (aka Voice Evacuation or PA/VA systems) are specialised emergency evacuation-assistance systems where Fire Detection and Alarm engineering is combined with Public Address expertise. This is the technical meeting-point of two prominent PEL Services expert capabilities.

Large public buildings such as retail shopping centresstadiums, theatres  Innovation campuses or exhibition halls must be equipped to protect visitors and staff by giving the occupants and visitors a fast, intelligible warning of fire and clear directions for immediate evacuation.


Retail & Shopping Centre Voice Alarm and Evacuation Innovation


Effective Voice Alarm and safe evacuation of the public requires specialist skills in design and installation, to ensure that emergency messages are clearly intelligible and the system satisfies an organisation's on-site emergency plan. Preparation of an emergency plan must involve input from emergency services and insurers to identify areas of primary risk, types risk and expected response times.


PEL's history of experience and innovation in Voice Alarm began in 1984 when PEL, encouraged by the London District Surveyors Association and the London Fire Brigade, worked with Arup Acoustics to issue a competent Voice Alarm specification. In 1994 PEL chaired a working group to establish a new code of practice for Voice Alarm (VA) systems, which subsequently became British Standard BS 5839: Part 8.


PEL designed and installed the largest Voice Alarm system of its type in Europe, at Westfield Stratford City shopping centre.


This system is a testament to the expertise of all involved in the design, specification and installation; it proved so good for bass-response as well as safety-first voice announcement intelligibility, that Nicole Scherzinger's performance at the official launch opening ceremony was fed through it, in preference to the dedicated performance system which had been hired specifically for her!




PEL engineers designed the system to be controlled from two independent fire command centres, employing the Bosch Praesideo system's IP-networked "daisy-chain" configuration, which facilitates freedom to design detection and sound-distribution for the unique characteristics of a building.


After taking stock of detailed Fire Detection system specifications, PEL used the Acoustic Consultant's analysis of the various acoustic areas to specify a range of different speaker types: Nearly 1500 loudspeakers were used in total, along with 45km of fire-resistant cable, 21 equipment rack locations and over 3 tonnes of batteries for back-up!
