- 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.

LS6512, LS6512-S; LS6513, LS6513-S
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. |
