Sprinkler cabinets should contain which of the following?

Sprinkler cabinets are essential for maintaining the functionality and safety of a fire protection system. Including a wrench and a list of installed sprinklers within the cabinet is vital for several reasons. Firstly, the wrench is necessary for any immediate adjustments or repairs that may need to be made to the sprinkler heads or connections, ensuring that the system can be quickly addressed in case of an emergency or malfunction.

Additionally, having a detailed list of installed sprinklers helps in identifying their types, locations, and any specific requirements or maintenance history. This information is critical for technicians during inspections, replacements, or system upgrades, as it provides a reference to ensure that all components are compatible and functioning correctly.

In contrast, while having spare sprinklers, a manual for installation, or a fire extinguisher may seem beneficial, these items do not collectively provide the immediate tools and reference needed for quick maintenance and response to issues. The combination of a wrench and an installed sprinkler list is far more practical for the day-to-day operational readiness of the sprinkler system.
