The City of Duluth installed 31 Whelen sirens beginning in Winter of 2008. There are 17 Voice Capable sirens along Lake Superior and another 14 Tone Only Vortex R4 sirens throughout the City. The system is two-way radio activated and monitored by a Computer Controlled GUI system and redundant activation is installed in St Louis County for use by any trained dispatcher at their console. Simple icons select what the sirens do; there are icons for Monthly Tests, Park Point Rip Current Warnings, Tornado Warnings, Severe Weather Warning, Chemical/Hazmat Incidents and many other types of emergencies. The sirens have been reportedly heard over 7 miles out on Lake Superior.
The City of Minneapolis awarded Frontline Warning Systems the contract to replace 30 existing Federal Signal sirens with 42 new Whelen Vortex R4 sirens. The project commenced in October of 2013 and had an ambitious schedule for completion by December 31st, 2013. All sirens use the Hennepin County Embedded Systems® controllers for activation and live monitoring. The Embedded Systems® controllers trigger a contact closure to trip each individual siren, selected groups, or the entire system. The Whelen Vortex sirens have tested and performed very well for this system due to their leading output and coverage, electronically controlled sound generation, internal history storage, and electronically controlled rotation (sirens keep rotating for 20 seconds after cancelled to refrain from noise complaints). The Embedded Systems® computer controlled GUI is a Polygon Based WeatherWarn® system and pages several hundred individual sirens throughout the Twin Cities.
Xcel Energy has been using Whelen WPS-2900 sirens for several different applications since 1990. Frontline has developed both an In-Plant All Hazard Warning System deployed at the Sherburne County Generating Plant (Sherco) and also a Dam Failure Warning System that spreads through many Counties throughout Wisconsin including Chippewa, Eau Claire, Dunn, St Croix, Sawyer and Washburn. The Whelen sirens have been installed in the event of a Dam Failure and siren activation is by far the fastest way to notify people of a catastrophic event such as that. The sirens are activated within seconds of an event, and the siren will sound with “Whoop” tones and Audible Instructions for 60 minutes or until cancelled. All sirens are two-way radio controlled, remotely monitored by 24/7 operators and several are also used by local communities and emergency management as Traditional Weather Warning Sirens
Cass County began install 16 sirens in Summer of 2010. This project was in partnership with the Leech Lake Band of Ojibwe (LLBO). That number has since grown to over 25 sirens in service. All sirens are voice capable and two-way radio controlled Whelen WPS-2900 units. The system communicates over a Simulcast repeater system. The system is operated by Cass County Sheriff’s office and dispatchers select from a few strategic icons on a selected dispatch console screen. The sirens have Monthly Voice audible recordings, but also are used for Tornado Warning, Hazmat incidents, severe weather, evacuations and even Public Address Announcements during local gatherings and Festivals. All sirens are Solar Powered, and perform perfectly in Minnesota’s Northern Frigid Climate!
Pierre, SD and Hughes/Stanley Counties have recently deployed a WeatherWarn® Polygon-Based Computerized activation system to activate and monitor the 24 sirens installed throughout the City of Pierre and the surrounding counties. This is a very intelligent operating system capable of extrapolating National Weather Service Warnings, Watches and Advisories and activating E-Mails, Text Messaging, Facebook announcements and Siren Activation for a Geographically selected area. This can be done automatically for selected events and/or manually for life-threatening events. All 24 Whelen WPS-2900 sirens are equipped with Professionally Recorded Voice Messages with fantastic audible range. The system is used for High Wind advisories, Fire Danger, Winter Weather parking restrictions, Tornado Watches and Warnings, Lightning advisories, Hazmat, Evacuation, Amber Alerts and special events. This is a cutting edge system and truly the future model for Mass Notification Systems!
The Military has used Whelen sirens and Frontline Warning Systems extensively as well. In 2014, Frontline upgraded 24 Whelen WPS-2800 and Whelen IPS systems in Minot, ND Air Force Base. The Minot Air Force Base installs Whelen “Giant Voice” for base-wide emergencies, announcements and bugle calls. Whelen WPS series sirens and IPS series products are exceptional for this application due to their reliable operation, sound coverage, easy integration and life expectancy. Frontline also installed redundant WeatherWarn® computer GUIs in strategic locations on the base for quick and easy system activation and monitoring. Minot AFB is not the only Military base to use Frontline Warning Systems for Giant Voice; Volk Airfield, Fort McCoy, Camp Ripley, Ellsworth, Sioux City, and Selfridge deploy customized Whelen systems through Frontline.
