• 3-function slide switches on side:
Position 1 (bottom) = Turns IR reader Off (supervision continues).

Position 3 (top) = Enables all features.
Operational procedures should be set in place to test the operation of PMTs and IRTs on
a regular basis.
Infrared transmitters (IRTs) send coded digital messages to an infrared receiver. Each message contains data
identifying the IRT Locator ID. IRTs should be ceiling mounted on opposite sides of ingress/egress points between
secure zones and/or in larger areas where location information is desired. Each IRT is powered by 12VDC and has a
draw of 155ma. They are often set up in series from an aggregate DC power supply. Each PMT contains an Infrared
receiver that reads valid IRT messages and decodes them. The location information is stored and rebroadcast via
the radio frequency (RF) 900MHz transmitter.
