HILO, BIG ISLAND (HawaiiNewsNow)
The Hawaii County Civil Defense Agency says 18 out of 71 sirens did not sound during Monday's emergency warning siren test. The majority of the malfunctioning sirens were in the Hilo and Puna areas.
Technicians from the Hawaii Police Department Radio Shop were called to trouble shoot a radio transmission repeater site in the Kulani area which provides for the radio signal communicationsl ink for those sirens.
A follow up siren test will be conducted in the near future. Officials say the public will be informed in advance of the tests to avoid any confusion or concern.
The current system utilizes radio signal technology to activate the sirens and requires that all sirens are activated at once. Officials say it is not possible to activate a single or specific area siren with the current technology.
However, the new technology that will be installed will utilize satellite communications and cellular signals as the two modes of activation and will provide flexibility with allowing for single or area specific siren activation.
