Public Address (PA) Systems, Installation & Maintenance

 

Public AddressPublic address systems are an essential tool in communication throughout a premises or campus.  ClearView has nearly 20 years experience of manufacturing, installing and servicing a wide range of audio and public address equipment.

 
Public address systems can broadcast information from single or multiple sources to large groups of people in:

 

  • Specific areas of a building – “zones”
  • All areas of a building – “all call”

 

Messages are sent from an operator via a microphone console or telephone handset and are routed through amplifiers before being distributed from speakers in the designated areas.

PA Systems can distribute music into work places from digital media or radio.

Voice Alarm Systems form part of the Fire Alarm Systems evacuation system where a spoken message gives clear details of the problem and identifies the necessary action to be taken.

It has been proven to be the fastest and safest method of evacuation because it delivers an emergency attention drawing signal followed by a recorded message, whilst also delivering live emergency announcements from the fire officer.

Standard facilities available on PA systems include:
 

  • Routine paging announcements
  • Background music,
  • Interfaces to other devices
  • Spot announcements


What can ClearView provide you?
 

ClearView can provide you with the confidence that your system will be designed, installed and maintained in accordance with all British Standards.  We will conduct site visits to establish and agree your needs and ensure that your system meets your exact requirements.

 
As legislative requirements of audibility and intelligibility can be stringent in complex acoustic conditions, it is critical that a system is designed and specified properly.

Our systems are designed and installed in accordance with the following regulations:

 

  • BS5839 part 8 for the UK
  • EN60849 throughout Europe
  • BS7827 for sound systems at sports venues


If a new public address system is required, our implementation process includes:
 

  • Examining your public address specification requirements, including minimum sound pressure levels and post installation speech intelligibility testing eg. STI or RASTI testing
  • Providing a detailed evaluation of the space that the PA system will serve
  • Seeking compliance with any performance specification and / or relevant standards.


If a public address system has already been installed, we will undertake commissioning exercises to determine the electro-acoustic performance of the system. This is likely to include measurements of speech intelligibility and audibility testing.

ClearView design, install and maintain public address systems as part of a Security technology solution. To discuss your public systems requirements, contact us today. Alternatively, find out more about us, read our latest news or review our customer testimonials and industry-specific case studies.
