Test of the talk-around phone
Test of the talk-around phone system on a Simplex 4100 U Panel. This gives personnel throughout the building easy access to communication with the panel operator. The individual handsets are simply plugged into various wall jacks placed throughout the building (usually near stairwells & elevators).
