PAS 122:2009 Specification for the installation of audiovisual equipment in classrooms and general publicly accessible areas
This Publicly Available Specification (PAS) specifies requirements for the correct and safe implementation of audiovisual installations.
This PAS was written to give end users and customers a level of confidence and assurance when purchasing audiovisual (AV) installation services.
PAS 122 provides requirements for the installation of AV equipment in a wide variety of settings. It is intended as a reference point for AV and electrical installers to ensure that the quality and standards of installations are raised to a sustainable level where any customer can be aware that specific criteria are being met.
In particular it has been noted over the past number of years that resellers of interactive whiteboards and AV equipment use third party sub-contractors to install their equipment. It has become apparent following completion of a number of audits that there are no strict guidelines relating to how the installations are carried out and that the processes employed by suppliers and subcontract staff differed greatly.
This adds to the risk as, in a few isolated cases, installs have been carried out without adhering to the appropriate processes. As such, the primary aim of this specification is to provide a framework that helps to ensure increased safety and analysis/management of risks, whilst also demonstrating due diligence in these areas.
Ultimately, an objective of this specification is to provide a means of assessment and certification in order to assure the users and wider industry of compliance with best practice. Wherever possible and where appropriate the equipment and installation processes should have measureable performance figures that can be validated by appropriate assessors and auditors.
This PAS is not a training document and therefore a suitably trained and or competent engineer is required to be able to carry out work to these guidelines.
It is assumed that the installer will have the relevant knowledge and understanding of the market place to suit the installation that is being undertaken.
A series of annexes include the following information for illustrative purposes:
- Further information on the technology referred to in this document
- Guidance on optical radiation safety
- A sample site survey document (pre-installation)
- Sample code of conduct
- A sample static load test
- A mechanical stability and static balance test
- General guidance for using whiteboards and projectors.
- A sample post installation document.
Although most of the above documents are samples for whiteboard and projector implementations this PAS is not restricted to this type of technology. It is intended to cover the many differing existing and emerging technologies used in the audio visual world.
PAS 122 does not specify requirements for the training of installation engineers. It is for use by audio visual installation companies in the UK who provide installations comprising of a significant AV component such as, but not limited to, computers, projectors, whiteboards, plasma screens, LCD screens, loud speakers (both wall and ceiling mounted) and light arrays to the public and private sectors and their end users.
