Douglas County (CO)

Douglas County is located between the City of Denver and the City of Colorado Springs. Municipalities within Douglas County include parts of the City of Aurora, City of Castle Pines North, Town of Castle Rock, Town of Larkspur, parts of the City of Littleton, City of Lone Tree, and Town of Parker.

Communications

A vast majority of public safety communications located within Douglas County can be found on the APCO Project 25 State of Colorado Digital Trunked Radio System (DTRS).

There are exceptions for areas on the northern and western edges of the county. These areas include Roxborough Park area of northwest Douglas County which is served by West Metro Fire operating on Metro Area Radio Cooperative (MARC), City of Aurora in northeast Douglas County which operates on Aurora EDACS, and the southwest portions of Douglas County which is served by North Fork Fire and Mountain Communities Fire on conventional VHF.

Normal users of DTRS may occasionally use VHF/800 conventional frequencies, especially in the more rural and mountainous parts of western Douglas County where DTRS coverage is insufficient or not used as the primary means of communications.

Fire Departments

Douglas County is protected by 11 different fire departments which include the Aurora Fire Department, Castle Rock Fire Department, Franktown Fire Protection District, Jackson 105 Fire Protection District, Larkspur Fire Protection District, Littleton Fire Rescue, Mountain Communities Volunteer Fire Department, North Fork Volunteer Fire Department, South Metro Fire Rescue Authority, West Douglas Fire Protection District, and West Metro Fire Rescue. A detailed map of these fire district boundaries can be found here (PDF).

Dispatch

Multiple dispatching agencies provide fire dispatching services for fire departments located both within and outside of the county. The two primary agencies that provide fire dispatching services in Douglas County are Douglas Regional 911 Communication’s Center and Metropolitan Area Communications Center (MetCom). Douglas Regional 911 dispatches for Castle Rock, Franktown, Jackson 105, Larkspur, and fire departments located within Elbert County on TG 1053. MetCom dispatches for South Metro on TG 1786 and West Douglas on TG 1791.

Remaining agencies not listed are generally dispatched by their own centers located outside of the county. Aurora is dispatched by their own Aurora Public Safety Communications Department on Aurora EDACS TG 529, Littleton is dispatched by Littleton Fire Rescue Communications Center on TG 1851, Mountain Communities is dispatched by Teller County on VHF conventional, North Folk is dispatched by Evergreen Fire Rescue on VHF conventional, and West Metro is dispatched by West Metro Fire Rescue's 911 Emergency Dispatch Center on MARC TG 37107.

All above dispatch agencies work on DTRS with exception of Aurora, Evergreen, Teller, and West Metro. Most agencies utilize radio operation channels as assigned by their own communications center unless they are responding to aid another agency. In the latter case, the aiding agency will likely switch directly to the requesting agency's operations channel if operating on similar systems or use a mutual aid channel such as Red SE/SW for dissimilar systems.

Unit Designators

Douglas County fire units use many numerical designators that can be used to help determine general location and departments responding to an incident. Note that not all departments operate entirely in Douglas County. These departments have station numbers that are physically located in the county in parenthesis. Other notes may also apply.

Identifier	Department	Staffing
1-15 * **	Aurora Fire Department	Career
1-15 (15)*	West Metro Fire Protection District	Career
11-18 (16-18)*	Littleton Fire Rescue	Career
31-47 (34, 36, 39, 40-41, 43-47)	South Metro Fire Rescue Authority	Career
130	West Douglas Fire Protection District	Volunteer
140	Jackson 105 Fire Protection District	Volunteer
150	Castle Rock Fire Department	Combination
160	Larkspur Fire Protection District	Combination
180	Franktown Fire Protection District	Combination
400 ***	Mountain Communities Fire Protection District	Volunteer
1200 **	North Fork Volunteer Fire Department	Volunteer

* Department operates separate stations and units with the the same designator.

** Department does not have a station within the county, but provides coverage for parts of the county.

*** Department operates in multiple counties and is unknown if there is a set designator for within the county.

Fire Tone Out

Douglas Regional 911 provides fire paging on 151.115 MHz mostly using Motorola Quick Call 2 tones. These pages are a simulcast of their dispatch talkgroup located on DTRS. Any scanner with the Fire Tone Out feature can be use the following tones to provide specific department notifications of calls dispatched within the county.

Department	First Tone	Second Tone
Castle Rock Fire Department	349.0	410.8
Franktown Fire Protection District	368.5	433.7
Jackson 105 Fire Protection District	368.5	539.0
Larkspur Fire Protection District	349.0	368.5

MetCom provides fire paging for the West Douglas Fire Protection District on 151.025 MHz and is patched to the West Douglas Fire Protection District talkgroup on DTRS.

Littleton provides call alerting using a single tone department wide on 154.340 MHz and is a simulcast of their DTRS channel.

Law Enforcement

Law enforcement for Douglas County is provided by the State Patrol, Douglas County Sheriff's Office, Castle Rock Police Department, Lone Tree Police Department, and Parker Police Department.

The Colorado State Patrol Troop 1C operates in Douglas County on TG 2301. Note that this talkgroup is often patched and may require additional programming to properly monitor. Additional information can be found at Colorado State Patrol (CO).

Other agencies can be found operating entirely within the county on their own respective channels with exception of Lone Tree which is dispatched by Parker.

Douglas County Sheriff's Office (DCSO)

DCSO is dispatched by their own in-house communications center on TG 1033. Patrol units are typically identified with three digits followed by a letter. The first digit of a unit's number represents the shift.

• 1: Day
• 2: Swing
• 3: Graves

This is followed by two additional numbers that represents the beat which the unit is assigned to, which can be found here (PDF). Beats range from 01 to 10 unless they are a Supervisor which are assigned 00. All patrol units are also assigned an additional letter that designate which car they inside the beat, starting with the letter A. Some examples are 203A (203 Adam) which is a swing unit in the 03 beat and is the first car of the beat or 300B (300 Boy) which is a graves supervisor and is the second supervisor of that shift.

Specialized units typically do not follow the above example and are assigned unique identifiers.

• 500: Community Service Volunteer
• 600: Traffic
  • Mary: Motorcycle
• 800: School Resource Officer
• Command: Admin (Lower number means higher rank)
• Ida: Investigations
• King: K9
• Lincoln: Lieutenant
• Paul: Off Duty

Codes

• A(dam): Dead Body
• BR stands for "Bulletin Report". The term bulletin comes from the old days when things were typed on a typewriter and then put on a clip board for interested persons to view, whether it be private citizens, the press or whoever. The codes are a quick way of giving the dispatcher the final disposition of the call so it can be closed with a disposition in the report.
  • 1: Gone on arrival
  • 2: No criminal activity
  • 3: False alarm
  • 4: No response (used by a supervisor only, they do not have, or do not want to commit a resource)
  • 5: Handled by other agency (Fire Department, State Patrol, Police Department, etc.)
  • 6: Field Interview card made on subject(s)
  • 7: Citation or ticket issued
  • 8: Not used
  • 9: Warning given

Note: DCSO has generally phased out code usage, but certain units may be found to occasionally refer to CRPD codes as they were once commonly used in DCSO.

Castle Rock Police Department (CRPD)

CRPD is dispatched by their own communications division on TG 2201. Patrol units are identified using a three digit identifier. The first digit of the identifier represents shift, the second is the district, and the third typically also represents shift.
