What is going to happen?
Motorola is flying in Engineers on January 29th. Around 2100 on January 29th, they will get into position at all the tower sites in Washtenaw County
A project mgr. will be located at HVA and Metro PD to discuss taking all the towers offline around 2am January 30th as long as there is nothing major going on in the county (PD chase, lg incident, etc)
As soon as the centers give a green light, all the towers will be taken off line. They will begin to update the software and firmware at the towers. Engineers will be at towers to troubleshoot any issues.
The State is bringing in a SOW (Site on wheels) to help with communications. It is being set up at the EMU tower to better cover YP, YT, SU areas for PD, FD and EMS.
AAPD, AAFD and other agencies in and around Ann Arbor will switch to the UM system
Fire station based radios will auto switch to towers out of the county once Washtenaw towers are shut down
Ambulances, Police vehicles and fire trucks should not need to press and hold the RSSI button to switch towers. This should be automatic
Each department should consider staffing their station with at least one firefighter
Once a call is received for the department. The station firefighter can send out a group text to have personnel respond if required depending on the incident.
Each fire station has a base radio station. The Consortium is going to go to each station and add Zone V (Paging) to add their paging talk groups. Once a call is received, dispatch will alert the station radio (causing it to beep until PTT is pressed) and dispatching information on the paging talk group and the dispatch talk group. FF’s at home should monitor their paging talk group via portable (if getting a signal)
Radio portable coverage will be reduced due to the outage in the county and bonk out of range will be often in some areas
AAFD and PIFD will be on UM FIREMED 1
All other FD agencies can use UM FIREMED 2. Remember, this is a back up system, wait for the channel grant and speak slowly and clearly. Sometimes there can be a lot of static due to distance and coverage. Dispatchers have to decipher what is being said.
All other FD agencies can also use WC BKUP F. Again, remember, this is a back up system, wait for the channel grant and speak slowly and clearly. Sometimes there can be a lot of static due to distance and coverage. Dispatchers have to decipher what is being said.
Worst case scenario – Command needs to stay in the truck using the mobile radio to communicate with dispatch and using a portable to communicate with onsite crews on Zone F ITAC talk groups.
The Dispatch center will announce when the towers are going down utilizing the 81PG911 for the pagers and the primary dispatch talk groups. Dispatch will also send a message to Active 911 and Edispatch that the system is going down.
Firefighters should make contact with officers if they do not understand how to get to the UM back up system, the WC (Washtenaw Co) back up system or zone F ITAC talk groups.
When dispatched to large incidents in Washtenaw, an Interop channel is generally assigned. Due to the tower outage, portables may not work on the MPSCS system. Incident Command may be using Zone F ITAC channels instead of Interops. Dispatch will advise which talk groups are being used for which incidents.
Dispatch CANNOT monitor Zone F ITAC talk groups. Incident Command will have to use a mobile radio in these situations to talk with the dispatcher or try the UM or WC talk groups based on their location to the towers.
Emergency buttons will not be reliable as the portable goes in and out of range with the tower.
