Access Control Applications

Simple AC Power Control
- simplest tools which can be controlled simply by gating main AC power
- should sense when tool is in use (via current sensing) to reset a timeout value
- e.g. basic power tools like saw, drill press, etc.
- mechanically encapsulate existing power plug to prevent circumvention
Complex AC Power Control
- equipment that can be controlled by controlling main AC power but which have extra safety/operational concerns
- may integrate with electro-mechanical sensors to infer state of the equipment (e.g. "auto lift arms are raised")
- may not have an easy means of implementing a timeout, for safety reasons
- e.g. auto lift, MSC mill, JET lathe
- probably hard-wired and integrated into existing controls/safety circuits
Logic-level integration
- simply gating AC power not preferred due to complexity of device
- equipment that can be controlled with low-level logic signals available internally on the equipment
- optional sensing of state to know when it's safe to lock out or to implement timeouts (e.g. knowing if laser or 3D printer are idle vs operating)
- e.g. laser cutter, 3D printer, MIG/TIG welder
Physical access control
- usually control an electro-mechanical locking device such as a solenoid door latch
- may have additional sensing for door open/door closed to provide audible alarm or reporting if left open
- e.g. interior doors, cabinet doors, electronic safe conversions
- future: maybe replace doorbot for exterior doors to standardize on one platform
