A dry pipe valve accelerator is found to be leaking. What does this condition indicate?

An accelerator leak may indicate the system has tripped, air pressure is dropping, or the accelerator itself is defective — all requiring immediate investigation.

A technician inspects a kitchen hood suppression system and finds the fusible links have been painted. What action is required?

Painted fusible links must be replaced because the coating can prevent proper melting at the rated temperature, delaying system activation.
During inspection, a fire pump is found to run but delivers no water pressure. The most likely cause is:

What is the purpose of the annual 'trip test' performed on a dry pipe sprinkler system?
