Impact on the System

The fire extinguishing system stops working during the replacement.

Preparations

Tools: hex key, Phillips screwdriver, protective gloves, step ladder

Materials: spare horn strobe

Documents: fire extinguishing device layout diagram (CE)

Skill requirement: fire engineer



For the diagrams, see the initial configuration parameter manual for the solution in use.



Before replacing the fire alarm bell, inform the related administrative departments of the
temporary downtime of the fire extinguishing system. After the replacement, inform the
administration department that the system has become operational.

Procedure
