Fire alarm commissioning and handover: what to expect
Fire alarm commissioning and handover explained: what commissioning verifies, the certificates and documents expected at handover, and what the responsible person receives.
Direct answer
Commissioning is the stage where the installed fire alarm system is verified to meet its design and to operate correctly; handover is when the completed system and its documentation are formally passed to the responsible person. As general guidance under BS 5839-1, you should expect commissioning checks, acceptance, and a documentation pack at handover — typically design, installation and commissioning certificates, an acceptance certificate, as-fitted drawings, the operation and maintenance information, and the log book. Confirm the exact certificates and documents expected against the current BS 5839-1 for your project.
Applies to

- Region: UK / Europe
- Standards: BS 5839-1
Installation vs commissioning vs handover
- Installation — the physical fitting and wiring of the devices, cabling and panel.
- Commissioning — verification, by a competent person, that the installed system matches the design and operates correctly (devices, addressing, cause-and-effect, sounders, interfaces).
- Handover — the formal transfer of the completed, accepted system and its documentation to the responsible person, after which their duties begin.
What commissioning involves
- Confirming the installed system reflects the design specification and the intended category of cover.
- Testing that each device is correctly addressed and located, and that the panel reports it correctly.
- Verifying the cause-and-effect programming (which inputs trigger which outputs) behaves as designed.
- Checking sounders, visual alarm devices, and any interfaces to other systems operate as intended.
Documentation expected at handover
- Design, installation and commissioning certificates, and an acceptance certificate — see What certificates should a fire alarm system have? for what each one covers.
- As-fitted drawings showing the installed devices and zones.
- Operation and maintenance (O&M) information / product manuals for the installed equipment.
- The log book, ready for the responsible person to begin recording — see What should be recorded in the fire alarm log book?.
What the responsible person should receive
- The full documentation pack above, plus a clear explanation of how to operate the panel and carry out the weekly test.
- An understanding that, from handover, they are accountable for routine testing, servicing arrangements and the log book.
When to contact technical support
- If the documentation pack at handover appears incomplete.
- If you are unsure whether the commissioned system matches the original design or category of cover.
Safety note
This article is general guidance for Hochiki Europe products. Installation, commissioning, maintenance and modification of fire detection and alarm systems must be carried out by a competent person in accordance with the applicable standards (for example BS 5839-1 in the UK) and the requirements of the relevant authority having jurisdiction. Always refer to the current product manual and data sheet for the exact model before carrying out any work.
