2. OTHER APPLICABLE DOCUMENTS
For intended use and relevant conditions for the safe use of the specific sprinkler, refer to the appropriate Technical
Data Sheet. In case an installed sprinkler needs to be replaced, refer to the appropriate Handling and Installation
Instructions for the installation of the new sprinkler.
3. MAINTAINING OPERATIONAL READINESS
Functionality
During fire conditions, the operating element fuses or shatters (depending on the type of sprinkler), releasing the pip
cap and sealing assembly. Water flowing through the sprinkler orifice strikes the sprinkler deflector, forming a uniform
spray pattern to control or extinguish the fire.
