Every fire system whether it is a fire detection or gas extinguishing system shall be issued with a log book.

Any system handed over to client without a log book is non-compliant to the South African Codes of practice.

SANS 10139: 13.2.1 states

A log book needs to be kept for the purpose of recording all events that occur in respect of the system, including fire signals, fault signals and work on the system. This information may be of value to the organization that services the system and if special action is taken to address false alarm problems.

The log book records details of the system, the client and the contractor. Information must be given to the client detailing:

  1. The responsible person
  2. Duties of the responsible person
  3. A record of all events occurring on the system
  4. Causes and remedies of false alarms
  5. Non-compliances of the system
  6. Category of the system.
  7. Details of the system installed

The log book provides information to show the system is inspected and serviced regularly and lists faults that will guide the technician servicing the system to deal with any re-occurring problems.
