Cox Bay Outdoor Warning Siren Electrical Upgrades

TOFINO B.C. – The District of Tofino (DoT) is upgrading electrical components in the Cox Bay Outdoor Warning Siren in order to ensure that the siren functions at its specified decibel level.

The DoT conducts monthly audible testing of the Cox Bay and North and Mid-Chesterman Beach outdoor warning sirens on the first Friday of each month at 11:00 am. In addition, silent testing of the warning sirens occurs on a daily basis. The purpose of this testing is to ensure that the sirens are producing their maximum sound output rating of 118dBC at 100 feet and that the radio control units are communicating effectively with the base station at the fire hall.

Through this testing, feedback from a resident in the area, and working with an electrical contractor we have identified some irregularities in the voltage that the siren receives from 2 out of the 4 amplifiers. This may affect the maximum sound output of the siren. To resolve this potential issue, new amplifiers will be installed, and additional measures will be taken to protect the electrical components from the harsh coastal environment.

The next test will take place, Friday, November 2, 2018, at which time the sound output rating will be tested with a decibel level meter to ensure the issue is resolved or to identify further action that may need to be taken.

In the meantime, please ensure you are subscribed to more than one method of emergency notification. The DoT follows international best practice by having several different notification systems in place within our community in order to achieve maximum warning to the public.

The Outdoor Warning Sirens are just one component of Tofino’s overall Emergency Notification System. The system is used in combination with several other methods, which include:

In addition to the emergency notification services provided by the District of Tofino there are a number of other official sources of information, such as: @NWS_NTWC, @PreparedBC, @EmergencyInfoBC, Emergency Info BC,,, and VHF Channel 16.

You can find more information about Provincial, Federal, and International emergency notification services available for subscription on the Districts website on the Emergency Preparedness and Tsunami Information webpages.
