System Upgrade

COIRS System Users:

As part of our ongoing system maintenance program, Motorola will be performing an upgrade to the COIRS radio system starting Monday, March 18th . This first week of the upgrade will involve the tower sites and connectivity and be mostly transparent to the users. However, we are expecting to experience at least four “site trunking” events.  These are scheduled for the following days/times:

  • Monday, 3/18 at 10:20
  • Tuesday, 3/19 at 08:40, 13:20 and 17:20

Each event will last approximately 10 minutes. Users will receive a “SITE TRUNKING” notification on their display, but talk-groups should continue to function normally and all sites will remain functional with no expected change in coverage. Dispatch consoles will lose connectivity and dispatchers will need to be prepared to use back up radios during these events.

As with any upgrade, the schedule can fluctuate.  NRECC and/or DELCOMM will announce over the radio, including LAW MUTUAL  before each event.

CS Lauren Yankanin will be the point person during the first week of the upgrade should there be any problems. You may contact her or Director Patrick Brandt of DelComm with any problems or concerns.

During the week of March 25th, Motorola will be visiting each of the dispatch centers to perform upgrades to the MCC7500 consoles. This will cause approximately 45 minutes of down time at each position. A specific schedule for change outs is being drafted and will be shared with you when it is ready.

LEERN End of Life

With all Central Ohio law enforcement agencies now on 800mhz and a common radio template coordinated so everyone has access to operational talk-groups, the patch to the state’s Law Enforcement Emergency Radio Network or LEERN is being discontinued. Officers and agencies are encouraged to do directly to the dispatch or TAC channel to contact an agency. When requesting the Chopper from CPD, they will come directly to your agency talk-group for communication. LEERN will be removed from the template during the next reprogramming.

We also have LAW MUTUAL , located in zones 6 and 9, used/monitored by all agencies in Delaware County, NRECC agencies and Worthington PD. The equivalent in Franklin County would be SO-25 which can be found in zone 28. Most importantly, your dispatcher can set you up on one of the many regional TAC talk-groups that are available for inter-agency use.

This will be effective at 0600 on November 1st.

Dublin Key Staff Radios

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.

Key Staff Template

Post Migration

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.

Site Trunking Event

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.
