Central Ohio Interoperable Radio System
Serving the safety & service forces of Delaware County, Dublin, Hilliard, Worthington and Upper Arlington
Key Staff TemplateStarting Monday 11/14, we will begin reprogramming the XTS-2500 radios that city staff have, with the exception of police.
These radios are mostly in use by crew leaders and supervisors/management staff.
If someone has one of these radios, they can drop them off on Monday at the service center between the hours of 1000-1400 or Tuesday and Wednesday between the hours of 1000-1400 at NRECC.
Information and updates will be found here.
On Monday 10/24, a meeting was held at NRECC to discuss the post migration template.
Present were Paul Richmond and Kris Harris (NRECC), Captain Pat Mulligan (Worthington Fire), Chief Mark Kidd (Pleasant Valley Fire) and Lieutenant George Sorge (NTFD). Lieutenant Kevan Redman (WTFD) was away at a meeting.
A tentative template was agreed on that will serve all agencies.
Columbus Fire went back to the drawing board and made revisions to their template, which is the base for ours. Our standardized template will be posted later this week when the Columbus fire revisions are included.
If you have any questions, please contact Paul Richmond.
The next meeting of the COIRS Governing Board will be held on Friday October 14th at 9:30am at the Worthington Police Department. CLICK HERE to review the meeting agenda.

15:10 – RESOLVED: Huntley Road tower is now back in service. XO completed repairs
08:00 ORIGINAL: The Huntley Road tower site is off line. It appears there is a problem with the XO network lines leading to the site. A service ticket has been submitted with XO and a technician will be dispatched to investigate. Users may see some degraded in building coverage in the Worthington area during this outage. A full service message will be posted when the problem is repaired.
14:15 UPDATE: The system has been restored to full service. Connectivity was restored and the routers restarted bringing the system back into wide area trunking.
13:17 ORIGINAL: The COIRS south simulcast is currently in site trunking due to a problem with the tower connectivity circuits provided by XO Communications. Roaming has been turned off and mobiles/portables can function normally. Dispatchers will need to use back up radios until the problem is resolved.
A full service message will be sent when service is restored.
The next meeting of the COIRS Governing Board will be held on Wednesday June 8th at 1:30pm at the Worthington Police Department. CLICK HERE to review the meeting agenda.

XO Communications notified COIRS that they will be performing emergency updates to the network switches that support our radio system between Tuesday (04/26) @ 23:45 and Wednesday (04/27) @ 06:00. There will be multiple connectivity interruptions of up to 2 to 3 hours during this time frame that will cause the system to go into site trunking.
Dispatchers will need to be ready to use back up radios/walkies during this outage. Although the consoles will remain connected, they will not be usable on COIRS talk-groups during site trunking & walkies must be used.
Field units will receive the “SITE TRUNKING” notice on their radios, but can continue to operate on their normal talk-groups. System roaming will be turned off during this time so that units won’t get separated onto the Delaware side of the system. Delaware County users will not be affected during this outage.
If you have any questions/concerns about the outages, please contact Jay Somerville
The COIRS simulcast has returned to full service as of 22:35 on 03/31. Circuit connection restored.
For any questions, contact Jay Somerville.
The COIRS simulcast is currently in site trunking (03/31 @ 22:00) Dispatchers should have walkies tuned to the talk groups in addition to the consoles to ensure all radio traffic is heard. The cause is a down XO circuit. XO repair has been notified.
Motorola engineers, along with staff from COIRS, completed the final checklist and officially brought the site up on the air this morning. This site is now bringing expanded area coverage and improved in building coverage in Hilliard, Norwich Twp and Brown Twp. The two channel expansion was also completed on all sites but will not be turned on until COIRS receives FCC approval.
