Text Alert Over Cisco Phones Will be Used Again with Site-Wide Alert to Remind Lab Community of Monthly Tornado Warning Siren Test at 10:30 a.m. on Jan. 3

Jefferson Lab's tornado warning siren will undergo its monthly operational test at 10:30 a.m. on Friday, Jan. 3.  Depending on weather conditions at the time of the test, the siren may be heard by anyone outdoors within a 1.5-mile radius of the lab.

Don't respond to the siren; this is a test of the siren system and not a personnel response exercise.

The test shouldn't last more than three-minutes.

Anyone in the Central Materials Storage Area (where the siren is located) while the test is taking place must have with them and wear two layers of hearing protection. A sign is posted at the CMSA gate to remind individuals of this requirement.

Jefferson Lab uses the siren to notify members of the lab community, who are outdoors, to Take Cover; in the event of tornadoes and tornado warnings.

Public Affairs sends out a Site-Wide Alert (SWA) email and page message on the morning of these tests so members of the lab community aren’t caught unaware when the siren sounds. It now also sends a tornado siren reminder text message to every Cisco VoIP phone at Jefferson Lab. When the message arrives on a phone, the red light on the handset will flicker a couple times and a tone will sound twice. The text message should be visible on the screen at point. The incoming text message won’t disrupt phone calls.

This alert notification feature was added to improve communication to indoor work areas where individuals aren’t close to their computers.
