State Civil Defense technicians flew to the Big Island on Friday to repair four sirens on the west side of the Hawaii island, according to a Hawaii County news release. They were among the 13 sirens that failed to function properly during the monthly test.

Over the weekend, Hawaii County Civil Defense and the Hawaii Police Department radio shop inspected and worked on seven sirens on the east side of the island, the news release said. Of those, two functioned properly, three were repaired over the weekend  and one was fixed today by a private contractor. State Civil Defense technicians returned to the Hawaii island today and repaired the siren at Laupahoehoe Point.

The two remaining sirens are at Hakalau, which was knocked over in a car crash, and at Waiaka, which has a frozen motor. That siren requires new parts and extensive work by private contractors, Hawaii County officials said.
