DEM-10 is a mobile communications vehicle on an ambulance chassis with amateur, public safety and commercial radios. It includes an ACU-1000 interoperability device used for patching radio channels and a laptop to run the patching software and record video from the aircraft video downlink. There are also two 800MHz handheld radios and a number of FRS radios available for loan. It can also provide power via a 3500 watt Onan diesel generator stored on board that runs off the main fuel tank. It is available to operate anywhere in Washington State on request.

Mobile IT Resource Unit
There are four cargo trailers configured with lithium (LiFePo4) batteries, solar panels, charge controller and inverter power system. These trailers were designed and built by DEM/ACS to provide general purpose power for communications and other operational needs. The fleet was designed to provide a powered utility for remote operations to support an EOC or other incident. These trailers were initially assigned to the COVID mass vaccination sites to provide Internet on site via Wi-Fi 24/7. They later created a Wi-Fi network in the fairgrounds parking lots during the fair, supported the Bolt Creek Fire command post and WSDOT at the Hwy 2 roadblocks. They also supported the command post at the Jim Creek Fire with Wi-Fi using Starlink as the Internet source.
Each trailer configuration is similar with the following chassis differences.
White, 5'x8', with full width swinging door in rear
Gray, 5'x8', with full width swinging door in rear
Black, 5'x8', with full width swinging door in rear and right-side man-door
Gray, 5'x12', with full width ramp door in rear and right-side man-door
The following documents describe the basis for these trailers, their applications and features.

Com1 & Com2
There are two vehicles that are nearly identical 34’ coaches designed as mobile command and communications vehicles. The front contains four operator stations with PCs and SNOPAC/SNOCOM CAD access and VHF and 800MHz radios. Position 4 has an amateur radio station with VHF/UHF and 220 radios. An ACU-1000 provides the ability to patch channels as needed.
There is cellular and satellite Internet access with Wi-Fi on board and printer/fax and network storage device. Phone is available via satellite or cellular service and fax available via cellular.
Two cameras are mounted on a 40’ pneumatic mast with satellite TV and aircraft video downlink all constantly recorded to a DVR. Seven TVs around the vehicle can display PC screens, any of the video sources or broadcast television.
The middle of the vehicle has a small refrigerator, microwave and coffee maker. The back of the vehicle has a small conference room. One of these could be deployed outside the County as long as there is still an operational unit in the County.
Mobile EOC (MEOC)
The Mobile EOC (MEOC) is one 20’ trailer designed to allow DEM to evacuate their current facilities and setup operations in any large room. The MEOC contains printers, laptops, supplies, wired and wireless networking equipment for computers and IP phones. There is a satellite connection that provides Internet and phone services and a NAS that has a copy of all the DEM forms and data from the County DEM S: drive. The aft area has some storage cabinets and a countertop with an 800 radio, VHF radio and amateur dual-band (2m/70cm) radio. The forward compartment has tables, chairs, portable awnings and two Honda 2000 watt generators. If the MEOC is not being used for DEM continuation of operations (COOP), it can be used as a volunteer registration center or as an EOC for another agency.
Mobile Highway Signs
Two mobile highway signs include AM broadcast band highway advisory radios on 600kHz and an MP3 player used to play the broadcast audio. The sign message can be changed from a keyboard locked inside the unit and an outgoing audio message is installed via an MP3 file on a thumb drive. The units are solar powered and contain two large banks of batteries on board for a nearly infinite run time. This makes them quite heavy and must be pulled with a large vehicle that has a pintle hitch. The WQNY586 FCC license cannot be used for commercial purposes and is only licensed within Snohomish County.
