Baltimore County Fire is divided into 3 divisions: Central, West, and East. Catonsville is in the West division. There is no need to avoid departments. That is why there are quick keys to turn them on and off using the keypad. In the file I created, I have only department quick keys 0 thru 9 enabled. That is all of County Fire. The police quick keys are 10 thru 22. Quick key 10 is Regional Auto Theft which covers all of the precincts. For the police precincts, add 10 to the number of the precinct for its department quick key number. Wilkens precinct 1 is quick key 11 and Woodlawn precinct 2 is quick key 12. There are no quick keys 15 and 20 because there is not a precinct 5 or precinct 10. If you want to toggle a police precinct on and off, press the decimal point twice followed by its quick key number followed by E. To turn on the Wilkens and Woodlawn precincts, press the decimal point twice, 11, and E for Wilkens and then the decimal point twice, 12, and E for Woodlawn. You must be scanning when you enable or disable departments. Use the same procedure to toggle a department off. County Fire Central division (Zones B and C) is on department quick key 1. County Fire West division (Zones D and E) is on department quick key 2. County Fire East division (Zones F and G) is on department quick key 3. The North division really does not exist. It is a holdover from when there were north and south sites and would be used if there were a site communication failure or major incident in the northern part of the county. Baltimore County now has a single simulcast cell. I have heard tone outs on a North division talkgroup, but that is all. Each fire division has 2 zones, each with a divisional talkgroup (Central, West, or East}, Dispatch, and Tactical talkgroups. The divisional talkgroup is common to both zones. The Dispatch talkgroup is common to all 3 divisions. You will hear Dispatch for the entire county on the Dispatch talkgroup The divisional talkgroups are generally used for EMS response and minor incidents. Larger incidents will be assigned a tac talkgroup. The main tac talkgroup for Central zone B is tac 12, Central zone C is tac 62, West zone D is tac 22, West zone E is tac 52, East zone F is tac 32 and East zone G is tac 42. If you only want to listen to Fire activity in the West division and Police activity in Wilkens and Woodlawn, you can turn off the other zones and divisions using the same procedure with the quick keys so that only department quick keys 2, 11, and 12 are enabled. The Baltimore County Fire talkgroups are set up exactly like the County Fire radios, using a template from Baltimore County Fire Communications. I program scanners for a lot of firefighters in my area.
