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.
