43.1 Commentary

In fire detection and alarm systems:

● Single Organization:

Small systems are often handled by one organization for design, supply, installation, and commissioning.

● Multiple Organizations:

Larger systems may involve separate entities for different stages (e.g., design by consultants, installation by contractors), leading to potential gaps in responsibility.

● Verification Requirement:

When multiple organizations are involved, a single verifying organization should issue a certificate confirming compliance with standards or documenting agreed variations.

● Scope of Verification:

The verifying organization, which could be involved in any of the stages or an independent party, may not be able to inspect every detail. The extent of verification should be agreed upon and detailed in the verification certificate or report.

43.1 Recommendations

The following recommendations are applicable.

Verification Requirement:

If there's concern about deviations from BS 5839 due to divided responsibilities, arrange for verification of compliance.

Competency:

The verifies should be knowledgeable in fire detection system design and relevant installation practices.

Scope Agreement:

The verification scope must be agreed upon with the purchaser or user, covering recommendations in Section 3.

Verification Certificate:

On completion, the verifies should issue a certificate confirming compliance or detailing variations, including information on the scope of the verification.
