PIR Sensor Interface….  (16 Pins)
LS6505, LS6505-S
Last Updated: 09/28/06
Selectable dead time
Triac output interface
Three selectable modes
Mode operation is determined by the 3-state Operation Select input.

  1. A Momentary logic 1 causes On condition and starts Auto operation. 15 seconds after Auto operation times out, Auto operation terminates.
  2. A momentary logic 0 causes Off condition.
  3. A momentary logic 1 causes On condition and starts Auto operation.
  4. 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.
