York County 911 Upgrades Electrical System

The York County Department of Emergency Services at 5:30 p.m. on Sunday, Dec. 7 returned 911 call-taking and dispatch functions to the York County Emergency Services Center from the 911 backup facility in West Manchester Township.

The transfer of calls to the backup center was needed so that contractors could cut power to parts of the Emergency Services Center, service uninterruptable backup power supplies and install a new electrical bypass around the backup supplies.

No 911 calls were affected.

The new electrical bypass will allow for future replacement of the uninterruptable power supplies without a transfer of 911 operations to the backup facility. It will also allow for quicker power recovery in the event of an unexpected bypass failure.

In the event of a power outage, the backup power supplies create a bridge that allows the building to continue running seamlessly until the Center’s generators engage and are able to provide electrical power.

A contractor this week is expected to create the necessary electrical connection between the new bypass and backup power supplies. That work is not expected to impact 911 operations.
