Some residents in Waialua were startled early Friday morning by the blare of an emergency siren.
Viewers told KHON2 via Report It that the siren sounded at approximately 2 a.m. and lasted for about three to five minutes, but with a different tone than normal.
The city’s Department of Emergency Management later confirmed that a siren went off in response to an alarm setting “that activates when the cabinet housing the components is tampered with or broken into. The alarm function was implemented to discourage break-ins and vandalism that have plagued quite a few of our outdoor siren warning systems over the past few years.”
If you hear a siren sound and there is no emergency information being broadcast over television, radio, or social media, you’re asked to call 911 to report it.
In most cases, the sound is likely due to a malfunction or break-in. In either case, a police officer or fire company will be dispatched to investigate and shut the siren off.
Malfunctioning or vandalized sirens or sirens that have been broken into will be scheduled for immediate repair by state or city technicians.
Sirens island-wide sounded as normal during the city’s monthly test at around 11:45 a.m. Friday.
