RICHARDSON – Crews contracted through the City have spent the last few weeks replacing Richardson’s 22 outdoor warning sirens.

“Our outdoor warning siren system is one method of warning. I want people to have multiple methods because during an emergency, you need multiple options in case something fails or doesn’t sound or doesn’t work,” said Alisha Gimbel, Emergency Management Coordinator.

The siren system overhaul includes new heads, control boxes, chargers, and batteries. In addition, each device will now have a solar panel. Strobe lights that flash when the sirens are activated will be installed in February.

Monthly testing will increase gradually from 30 seconds to three minutes as recommended by the manufacturer. The plan is to start conducting 90-second tests in January, and adding a weekly low-tone growl in April in addition to monthly testing.
