39.1 Commentary

a) Purpose:

Ensure the system operates correctly per the standard and specifications, and confirm all documentation is handed over.

b) Responsibility:

Clearly define who is responsible for commissioning before installation starts.

c) Scope:

The commissioning engineer verifies system operation and installation quality but typically does not check design conformity to all standards. They should be knowledgeable about fire alarm design practices and the relevant standards.

d) Documentation:

The commissioning engineer must have the system specification and ensure compliance with principles aimed at avoiding false alarms.

39.2 Recommendations

1. Competence and Documentation:

● The commissioning must be conducted by a qualified individual who has access to the system’s specifications and relevant documentation.

● The person responsible should have foundational knowledge of Sections 2, 3, and 4 of the standard.

2. Inspection and Testing Requirements:

● Functionality Checks: Ensure all manual call points and detectors operate correctly. Confirm labeling and visual identification are complete. Verify correct zone indication and text display in addressable systems.

● Optical Beam Detectors: Minimize reflection effects and test by partial beam obscuration.

● Sound Levels: Confirm that sound pressure levels and intelligibility meet the specified requirements.

● Remote Transmission: Test the functionality of remote transmission systems for fire and fault signals, ensuring proper notification procedures are followed.

● Cause and Effect: Validate that "cause and effect" requirements are met, including alarm stages and integration with other systems.

● Overall System Operation: Check all system functions, labeling, and ensure no design compromises due to building changes.

● Detector Siting: Verify compliance with siting recommendations for manual call points, various detectors (heat, smoke, carbon monoxide), beam-type, line heat, and aspirating systems.

● Visual Alarms and Power Supplies: Ensure visual alarms and power supplies meet specified standards. Confirm battery labels and system load predictions.

● Documentation: Confirm that all relevant documentation is provided to the user and that insulation resistance, earth continuity, and fault indicators are properly tested and recorded.

● Radio-Linked Systems: Ensure adequate radio signal strength across the protected area.

3. Certification:

● Upon completion, issue a commissioning certificate signed by a competent person, as per the prescribed model.

In commissioning, it is essential that all tests are conducted as outlined and any discrepancies are documented and addressed with the designer or purchaser. This process ensures the fire detection and alarm system operates effectively and meets all safety and operational standards.
