  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.

LS6511, LS6511-S
LS6512, LS6512-S; LS6513, LS6513-S NEW!
Last Updated: 09/25/09
LS6512 same features as LS6511N except no Low Voltage Detection
LS6513 same as LS6511N and LS6512 except Low Voltage Detection is User selectable and Enable function is an added feature which is also User selectable

LS6512 is ideal for automatic doors; motion-triggered remote monitoring (for cameras, etc)
LS6513
can be used in any application in place of LS6511N and LS6512 determined solely by the User selected features.
