The mechanical parts that complete a fixed suppression system beyond the cylinder, valve and nozzle: manifolds that combine multiple cylinders into one discharge path, actuator assemblies that convert the release signal into mechanical action, pressure switches that confirm discharge back to the panel, and the associated fittings.
Every one of these is matched to the system design. Pressure switches in particular are the panel's proof that discharge actually occurred, so a substitution changes what the system reports. Order from the system drawings.
