23.4 Preparatory work
Inform the system owner
Inform the system owner of the scope and expected duration of work and also that
↑ 'Site' operation will be restricted.
For large-scale systems fill out the system shutdown notification sheet and have
this signed by the system owner.
Block system components
Block the following system components:
● Remote alarm (log out on the receiving center)
● 'Fire controls' and alarm equipment
● Extinguishing stations
Specify the procedure
Stipulate the times for the following test sequences with the system owner:
● Test alarms (including remote transmission)
● Performance check for 'Fire controls'
● Additional instructions (if required)
● Clarifications (if required)
