1. Introduction This document sets out the Loss Prevention Certification Board certification

requirements for fire detectors. It is specific to smoke, heat, flame and Carbon-monoxide fire detectors. The performance and test requirements are given in the standards listed in Section 9. The aim of this scheme is to ensure that detectors used in fire detection and alarm systems installed in buildings comply with the requirements specified in the appropriate standards, which should minimise the risk to people and/or property.

2. Scope This scheme provides ongoing independent, third party assessment and certification/approval of detectors to ensure that the requirements of the appropriate standards are met and maintained. This scheme document must be read in conjunction with PN 110 “The product certification process”.

3. Testing of Products

Section 9 lists the applicable standards for various types of detectors. In order to achieve certification or approval, the detector must comply with the requirements specified in the appropriate standard(s) dependent on its designed detection principle(s). The product will be tested periodically for continued compliance with aspects of the standards; Section 10 sets out the audit testing requirements. All samples supplied for testing by the manufacturer must be representative of normal production and fully traceable to a specific production batch through quality control records.

4. Applications to join the Scheme To apply for product certification complete and return the appropriate application forms and submit the technical drawings and documentation as specified in the application form. Your application will be reviewed and, if acceptable, a quotation will be prepared. This will detail all relevant costs, estimated project duration, sample requirements and a period of validity for the quotation. The quotation will be subject to BRE Global Ltd’s Standard Terms and Conditions as detailed in PN101. For more information or help with your application contact BRE Global on 01923 664100.

5. Management Systems Certification to ISO 9001 In order to ensure that the detectors meet and continue to meet the requirements of the standard(s), we expect the manufacturer to maintain full quality control of the production process. For LPCB listing the manufacturer must have ISO 9001. Where applicants hold ISO 9001 with another Certification body, LPCB will carry out Factory Production Control (FPC) assessments. The applicant must also meet the additional requirements set out in Section 11. Full details of the ISO 9001 certification process are set out in SD003 ‘Management System Certification Schemes’.

6. Certification A certificate is awarded following satisfactory completion of the assessment programme by LPCB. Certificates remain valid providing there continues to be:

• Satisfactory results from the annual product audit testing programme set out in

Section 10.

• Satisfactory surveillance results as assessed by LPCB in respect of FPC or ISO 9001 requirements and the requirements identified in Section 11.

• LPCB approval of any proposed modifications to the product which may affect

performance. Requests to assess proposed modifications are made by completing the modification application form.

The applicant will be advised of any further requirements where necessary to retain certification.

7. Alternative Marking (Cross Listing) In certain circumstances, LPCB listed products may be branded with another company's name and product identification incorporating the LPCB Certification Mark. Products that are LPCB approved and Red Book listed for the original manufacturer can, with the agreement of the Owner of the product, be approved and Red Book listed under the name of another company, under a different name or brand. This can be done without having to undergo the full approval process so long as the actual product is not significantly changed in design, construction or function.

8. Certification Mark

The Supplier may use the LPCB Certification Mark as directed in the publication PN103 ‘Rules and Guidance for use of the LPCB Certification Marks’. The Mark that may be used for this scheme is as follows:



Issue No.: 5.2

Alternatively, if there is limited space on the product, the following mark may be applied instead.

EN54-nn ssue: YYYY

Cert/LPCB ref. XXX/XXa 9. Type Testing Requirements: The number of samples selected for type testing is dependent on a number of factors, for example:

(1) The standard(s) the detector to be tested to. (2) Detector sensitivities, classifications or modes of operation. (3) Specific detector features to be tested.

Testing will be performed by a UKAS (or equivalent) accredited laboratory acceptable to the LPCB. If no standard is available for testing a specific detector type assessment of the detector will be made against an LPCB test schedule developed and agreed by LPCB, LPC/BREG laboratory, and manufacturers’ technical representatives. Risk assessment for such detectors will be carried out and approved by Expert Group A. Marking will be examined for compliance with the relevant clause of the standard and LPCB publication PN103. Documentation requirements shall include technical information of the products submitted for approval. This includes:

- Schematic diagrams - Installation & operating instructions - General assembly drawings - PCB artwork - Mechanical drawings

Page 7 of 32


Failure to meet any of audit test requirements shall be communicated to the client in the form of a report detailing the nature of the failure and the following shall be applied:

- Clients will be expected to investigate the matter and provide a satisfactory

explanation including details of the corrective action to be reviewed by LPCB. The client must respond to the failure within the specified time limit. If the Client fails to respond by the given deadline or LPCB deem the response to be unsatisfactory then the product approval may be suspended.

- If the product is suspended then all LPCB marked devices held in stock or in

transportation must be quarantined until further notice.

- Investigations or further testing which arise as a result of any failure identified during the product audit will incur additional costs.

- Following any suspension of product approval, a final deadline will be set for the

matter to be satisfactorily resolved. Failure to resolve the matter by the final suspension deadline may result in the full withdrawal of the product approval.

Note: Products may be suspended immediately once a failure has been identified depending on the nature of the failure. All timescales involved will be at LPCB’s discretion. 11. Additional Factory Production Control Requirements

Table 3 : FPC Requirements

Topics Notes Checks and tests

The production process should include functional and performance checks to monitor the production process and in particular the sensitivity settings of the detectors. All detectors should be subjected to functional tests that include checks of the ability of the detector to signal an alarm, or in the case of analogue addressable detectors, the correct operation of the signalling protocol. At least a representative sample should be subjected to a performance test that involves stimulating the sensor with the appropriate fire parameter (e.g. smoke, infra-red radiation … etc).
