The equipment was installed at the pavilion in Grangemouth’s Inchyra Park on Saturday.
Adam Gillies, of Friends of Inchyra Park, said: “We thank Friends of Forth Valley First Responders who supplied and installed the defibrillator – the first of five being installed in Grangemouth.
"We hope it is never needed, but we’re so grateful to have this life saver in the park.”
