Maintenance Alert: Upper Arlington

Tonight (12/28/18), starting at 1900, the City of Upper Arlington will be doing maintenance on the fiber optic network that connects the COIRS radio tower located at Station 72. This maintenance will take that site off line. The outage could last up to 8 hours and will degrade in-building walkie coverage in and around UA, especially south of Lane Ave.

UAPD and UAFD will remain on their normal COIRS talk-groups and will only move to COIRS LE or COIRS FD if the need arises. For any in building fire responses, it will be the discretion of the IC whether to move the response to COIRS FD.

All other COIRS towers will remain in service during this maintenance.

If you have any questions, please contact Jay Somerville.
