Whelen 2900 series

Whelen 2900 series

The Whelen 2900 Series is a group of Omnidirectional Civil defense sirens similar to the Federal signal modulator. Each model begins with 2900 and the model numbers change due to the different amounts of disks on the siren. These sirens are used (along with the Federal Signal 2001 series) in replacement of the Thunderbolt siren.
