After the outdoor warning signal test last week, it was determined that Warning Siren #8 (located at Agnes Patterson Memorial Park) is non-functioning. RACOM (Jasper County’s public safety communications company partner) was in town the afternoon of Friday, April 8 to test the unit and found that it was not decoding. At this time, the City has sent the control board to Federal Signal (the outdoor warning siren company) to diagnose and repair. All other outdoor warning sirens passed the test last week. The distribution of the outdoor warning sirens in the community create redundancy and overlap in coverage in the case that the outdoor warning sirens are needed to warn of severe weather.
On Sunday, April 10 it was reported that outdoor warning sirens were going off in Newton. Jasper County Sheriff’s Office did a check and the outdoor warning sirens were going off due to a technical difficulty stemming from a radio skip from outside of Jasper County. A radio skip occurs when another jurisdiction is using the same radio frequency (sometimes as far away as 500+ miles) as our emergency communication channels. Due to atmospheric conditions, sometimes the radio frequencies can travel much further than normal and can cause interference with the radio frequencies on public safety communications – including the outdoor warning sirens.
Due to the severe weather in the forecast, please make sure to turn on your WEA notifications on your cell phone and sign up for the Alert Iowa notifications (text JASPERIA to 67283 to receive alerts or visit http://bit.ly/JasperAlerts).
