LS6505, LS6505-SLast Updated: 09/28/06
Selectable dead time
Triac output interface
Three selectable modes
Mode operation is determined by the 3-state Operation Select input.
Op Sel Input Mode A Mode B* Mode C
Logic 1 On (1) (3)
Open Auto No change Auto
Logic 0 Off (2) (4)
A Momentary logic 1 causes On condition and starts Auto operation. 15 seconds after Auto operation times out, Auto operation terminates. A momentary logic 0 causes Off condition. A momentary logic 1 causes On condition and starts Auto operation. A momentary logic 0 terminates Auto operation and causes Off condition. After 8 seconds, Auto operation resumes.
*Note: Mode B is compliant with California Title 24
Wall switch sensors are adaptable to 3-way operation with a remote switch.
Ideal for wall and ceiling mounted occupancy sensors providing energy savings and convenience.
PIR Sensor Interface…. (14 Pins)
