Power back up system for the SL-3000-UL DM commercial gate operators.
Don't be a prisoner of your own gate. Using the DC-2000 SL DM keeps traffic moving during a power failure.
Fail Safe: In case of a power failure, the gate will open automatically. When the power is restored, the operator will return to normal behavior.
Fail Secure: Gate will not open automatically until activated by a key switch, push button, or dry contact adjustable command.
What's the difference between "Fail Safe" and "Fail Secure"?
