LED Status Indicators

The Safety Relay state is shown by its LED.

LED	Status
Green	Functioning normally, door latch is locked.
Blinking Green	Functioning normally, door latch is unlocked (relay is activated).
Red	Tampering detected, door is locked-out to ignore door open requests from the Video Intercom (on the I/O pin) to prevent entrance, but input from REX sensor can still unlock door to allow exit.

When the LED is steady red, the tampered state can only be cleared by pushing the clear button on the Safety Relay. The tampered state should only be cleared after the tampering incident has been resolved.
