The Colony Fire Department has made some recent software upgrades to the city's Outdoor Emergency Warning Sirens. As a result, certain changes to the system's performance have taken effect.
Namely, “quiet” testing will now take place on a weekly basis every Wednesday at noon (with the exception of the regular test the first Wednesday of each month). During quiet testing, all the sirens will rotate for 15 seconds and sound briefly (less than a second). This is a routine maintenance feature that allows for checking the status of the system more frequently. In the event of any failure, electronic notifications are made to TCFD admin staff and the siren maintenance contractor for immediate repairs.
Another upgrade is that the regular signal has been changed to a steady tone. The steady signal allows for the siren to be at full output throughout the entire duration of the activation. This is to address the low portion of the previous wail being difficult to hear as the siren rotated.
