Inadvertent Emergency Siren Activation This Morning, 2/7/20
posted on 02/07/2020.

System malfunction caused emergency sirens to activate at 4 am this morning

At 4 am this morning, February 7, 2020, the City’s Emergency Siren system inadvertently activated. We are currently investigating the cause of the situation, which is attributable to a malfunction of the system that controls the sirens at our fire stations. Early warning systems are an important part of alerting our HB residents and visitors, and the safety of our community is our number one priority. Early notifications during an emergency are a critical component of our emergency planning. This siren system is just one of multiple systems that are used to notify residents of an emergency. It is a priority of the City to resolve the issue as quickly as possible and we apologize for any inconvenience.

The City’s Emergency Siren system was designed to be activated to notify residents of possible impending threats, and are not specific to any one emergency. When the system is turned on, it is intended to signal the public to seek more information about an emerging threat. If there had been an actual emergency this morning, public safety officials would have sent out messages to the public through the AlertOC system, Wireless Emergency Alert system and social media outlets. Also, in an actual emergency, the police department requests that you not call 911 to get information. Call 911 only if you have a life threatening emergency. Please call the City’s non-emergency numbers: Fire 714.780.0986 or PD 714.960.8811

Of note, the sirens are tested on the first Friday of each month at noon. The test scheduled for today at noon will not take place. The system has been taken offline temporarily until the issue is resolved.

The City would like to take this opportunity to encourage you to register your phones for the AlertOC notification system at Also, for more information on what you can do to prepare an emergency visit:
