Relay activation begins when the detection area is entered and remains on for the duration of the preset relay timing. The unit is designed for concealed and easy installation in suspended ceilings. Four interchangeable detection patterns are standard with each unit. Units accept a power supply range of 12 to 24 volts AC or DC.

In addition to the four standard interchangeable detection patterns, others may be custom made. The T-80 activates both when someone enters the detection area and again at exit and is used for access control and other motion detection where multiple alarms are acceptable or where people may pause for long periods within the detection area before exiting. The S-80 activates only when the detection area is entered and ignores exits from the detection area. The S-80 is used for annunciation in offices or classrooms where short single alarms are desired.
