Automatic sprinkler, water spray and deluge systems


INTRODUCTION

The standards used by LPCB for approving and listing sprinkler system components have been developed to ensure that they are suitable for use in systems installed to the LPC Sprinkler Rules incorporating EN 12845.
  
Many of these components may also be suitable for use in systems designed in accordance with other international and national codes such as NFPA.
  
To ensure that the systems work, it is recommended that they are designed, installed, commissioned and maintained by contractors who are approved by LPCB to LPS 1048 (for commercial systems) or LPS 1301 (for residential or domestic systems).

    Installation and maintenance contractors
    Contractors are approved in accordance with:
      
  • LPS 1048: Requirements for the approval of sprinkler system contractors in the UK and Ireland.
      
        
  • LPS 1148: Requirements for contractors engaged in the design, installation, commissioning and servicing of automatic sprinkler systems (overseas)
  • LPS 1301: Requirements for the approval of sprinkler installers in the UK and Ireland for residential and domestic sprinkler systems.
        


    LPS 1048 approved sprinkler contractors - UK and Ireland

    Sprinkler systems are only effective if designed, installed and maintained correctly. The LPS 1048 scheme: Requirements for the approval of Sprinkler Contractors in the UK and Ireland, ensures that installers are capable of designing, installing and servicing sprinkler systems to acceptable installation standards.
      
    Scheme Structure
      
    There are 4 approval levels for Sprinkler Contractors in the LPS 1048 scheme. Figure 1 below shows the Categories of Work that are allowed to be carried out at each approval level in the LPS 1048 scheme.


    √ 1 -     Allowed to undertake this Category of Work under supervision
        √ 2 -     Allowed to undertake this Category of Work, supervision may be required depending on whether the Contractor has been granted self-certification for this Category of Work.
    √ 3-    Allowed to undertake this Category of Work, Contractor can self-certificate this Category of Work
        
    X -    Not Allowed to tender or undertake this Category of Work
      
      
    Important Note to Specifiers
      
    Specifiers should only use Sprinkler Contractors that are LPS 1048 approved to the appropriate level depending on the type of sprinkler work required, refer to the individual company listings for the approval level of Sprinkler Contractors.
      
    Listing of Sprinkler Contractors
      
    LPS 1048 Approved Sprinkler Contractors are listed alphabetically, regardless of their approval level.
      
    Continual Assessment
      
    The LPS 1048 scheme has over 80 sprinkler contractors that are continually assessed for their continued capability to undertake sprinkler contracts and for their compliance with the requirements of the LPS 1048 scheme.
      
    Certificates of Conformity
      
    In order to ensure that a sprinkler system is effective, specifiers should always request an LPS 1048
    Certificate of Conformity. An LPS 1048 Certificate of Conformity may only be issued for a sprinkler system, installation, extension or alteration that is in full compliance with the one of the acceptable installation standards.
      
    Any agreed minor deviations to the installation standard will be recorded on the LPS 1048 Certificate of Conformity. An LPS Certificate of Conformity cannot be issued if there is a major deviation to the installation standard. It should be noted that a Sprinkler Contractor's Completion Certificate is NOT an LPS 1048 Certificate of Conformity.
      
    An LPS 1048 Certificate of Conformity only remains valid if the sprinkler system, installation, extension or alteration, covered by the certificate, is serviced and maintained in accordance with the original installation standard.

    Supervision
      
    Where an approved Sprinkler Contractor does not meet all the criteria set out in the LPS 1048 scheme document to self-certificate any of the Categories of Work allowed under its approval level, it is required to have the Category (ies) of Work that it is not approved to self-certificate supervised by an LPCB approved Supervising Body or the LPCB Supervisory Service.
      
    Supervision involves a review of the design, an inspection of the installed sprinkler protection, and if water supplies are included in the scope of work, witnessing of the water supply proving tests, for compliance with the installation standard. For supervised contracts, the LPS 1048 Certificates of Conformity is issued by an LPCB approved Supervising Body or the LPCB Supervisory Service.
    Details of the Categories of Work that each approved Sprinkler Contractor can self-certificate, can be found in the individual company listings.
      
    Financial assessment
      
    The assessment and listing of Sprinkler Contractors in the LPS 1048 scheme covers only technical and quality aspects. All other contractual requirements are the responsibility of the parties to the contract.
      
    Service and maintenance

    Installers that undertake service and maintenance work are assessed for their capability to carry out such work in accordance with EN 12845 clause 20 and Technical Bulletin 203 of the LPC Rules for Automatic Sprinkler Installations.
