Check a system that stopped responding after a power interruption

Tell us which devices came back online and which stayed off after the interruption. We assess the supply, connected equipment and controller state before recommending a repair. Network-dependent functions and local door operation are considered separately.

What the repair assessment includes

We compare the reported symptom with the reader or keypad response, controller operation, connected power and the physical door. The proposed work identifies the affected component or setting and any compatibility limits. After approved work, the affected entry methods, installed exit controls and door closing sequence are checked.

What affects the estimate in Mount Sinai

The number of affected entrances, equipment support, required parts, wiring access and the need for separate door-hardware work affect the scope. Send your full property address and system details; availability and the proposed work are confirmed before scheduling or approval.

Does a power interruption prove the controller is damaged?

No. Loss of supply, backup-power condition or equipment that has not reconnected can look similar. The affected components need to be checked before damage is concluded.
