(KMOV) – St. Louis County officials say a malfunction caused emergency sirens to go off on their own Monday morning at the wrong time, creating a false alarm for residents.
The sirens are tested the first Monday of the month at 11 a.m., but this Monday they sounded at 9 a.m.
A specialist at the county’s Office of Emergency Management in Chesterfield says the problem is outdated technology, dating back to the 1960s.
However, next summer, the county will have a new siren system installed as a result of the E-911 sales tax increase approved by voters in 2009.
The county says about 25 percent of its 200 sirens are not working properly.
The new emergency alert system will replace some of those sirens, and will update the technology.
