Wednesday, Nov. 29 at 5:30 p.m. JLab Will Test its Public Address System

On Wednesday, Nov. 29, members of the Jefferson Lab Emergency Management Team will conduct the recurring test of the lab’s Public Address (PA) System – the live audible announcement feature – available through speaker on the Cisco phones.

This operational test of the system occurs one evening every other month at 5:30 p.m. No actions are required or expected from members of the lab community with this test.

The Public Address System may be used to notify members of the lab community, who are indoors, of critical emergency situations requiring immediate action, such as taking cover for a tornado warning.

The test is conducted after normal business hours because the PA tool is potentially disruptive when it is activated: It interrupts any in-progress call on a Cisco phone. Active calls are automatically put on “hold.”  As soon as the PA announcement has ended, the JLab person may re-activate their call.

The test announcement won’t last more than 30 seconds, and will clearly state that it is a test of the system.

Members of the lab community with feedback or observations regarding tests of the PA system, or regarding emergency communications in general, are asked to email their input to Jefferson Lab's Emergency Manager, Tina Menefee, at
