LPS 1223

AFS (1993) Ltd have been approved to install the Amerex Wet Chemical System to the LPS1223 standard since March 2000.

Currently only TWO manufacturers are approved to this standard. Ansul and Amerex

The LPCB Approval Scheme for fixed fire extinguishing systems for catering equipment has been developed in recognition of the specific risk posed by oil fires in cooking appliances of catering or food production establishments.

The objective of the scheme is to ensure that the Listed systems provide adequate protection of the cooking appliances, hood, filters and extract system when correctly installed, serviced and maintained by trained personnel.

Please Note

To reduce the potential for fires in the extract ductwork, the fixed fire extinguishing system should be installed in conjunction with a grease filtration system meeting the requirements of LPS 1263:Part 1: Fire Performance Requirements for Kitchen Extract Systems.

Product Testing

The systems listed below have been tested against LPS 1223: Requirements and Testing Procedures for Approval of Fixed Fire Extinguishing Systems for Catering Equipment the main requirements of which cover:

• System specification
• Design manual assessment
• Component testing
• Fire extinguishment tests
• System testing, including extinguishing agent discharge tests

Traditional extinguishing agents do not readily extinguish catering equipment oil fires because they do not provide sufficient cooling effect to reduce the cooking oil to below its auto-ignition temperature. The fire extinguishing tests in LPS 1223 recognise this requirement together with the need to ensure that neither the composition of the agent nor the manner in which it is discharged onto the fire causes flaming oil to be ejected.

Authorised Installer Requirements

Such fixed extinguishing systems rely upon competent designers and installers and as such LPS 1223 contains requirements placed upon the listed manufacturers to ensure they maintain adequate control over their authorised installers. LPCB regularly audits the companies listed below to:

• Check that adequate control over the authorised installers is maintained. If LPCB do not audit all regional operations then the necessary information shall be available at the main site during audit;
• Check that systems faults are reported and actioned appropriately by the listed company and/or their authorised installers; and
• Carry out product audit checks.

Fish and Chip Ranges

Fish and chip ranges are a specialised type of catering equipment that require special consideration with regards to protection, based on the position and orientation of the extract system.

Unless otherwise stated in the individual product entries, the Listed systems are not approved for protection of fish and chip ranges.
