OmniDirectional Electronic Siren Series
Category: Outdoor Notification
Federal Signal's Modulator Series Siren, a family of electronic sirens, produces high intensity warning signals over a large area. A Modulator siren consists of an omni-directional speaker array and a siren control unit/battery cabinet (purchased separately - see the UltraVoice Electronic Siren Controller). A highly efficient design enables the siren to produce a high sound level, while making moderate demands on the battery power source.
The innovative Modulator Siren Series speaker array consists of modules that utilize four (4) 100-watt drivers per module. The Modulator is available in several models rated from 106 to 125 dBC at 100ft/30m.
Signal Description: The Modulator Siren Series controller provides a flat frequency response from 200 to 2000 Hz for excellent voice reproduction and with the UltraVoice Controller produces warning signals such as:
- WAIL (ATTACK)
