NATIMUK will be without a fire siren until the siren is repaired.
Country Fire Authority District 17 duty officer Trevor Ebbels said the siren had been reported as faulty and was being fixed.
Mr Ebbels said volunteer fire-fighters still had their pagers, so they would continue to be notified of fires.
Natimuk Fire Brigade captain Mark Uebergang estimated the fire siren had been out of service for several weeks.
He was unsure when it would be repaired.
"Because the fire siren is up a tower, you need someone with the qualifications to reach it," he said.
"We have members who have cherry-pickers and could get it down in a flash.
"But it has to be done by properly qualified people.
"The fire siren will be out of service until then."
Mr Uebergang also confirmed that the fire brigade was using a spare rural tanker while their usual one was being checked for its lack of horsepower.
He said the tanker failed to keep up to speed with other tankers while travelling to call-outs.
