Requirements & Capabilities

Equipment is patented by Communications - Applied Technology (C-AT) and there are various configurations ranging from 2 radios w/1 talkgroup to 10 radios w/4 talkgroups we will concentrate on the 5 radio, 2 talkgroups option 5 radio I/O, 1 telephone I/O, handset/headset I/O, 2 talkgroups Small (10” x 3” x 7”), rugged package/ circuitry Portable (3.5 lbs) Rapidly deployable (typically under 5 min.) Minimal “operator” training required Alternate power sources: 115-220V AC 50/60 Hertz, vehicle-

supplied 12 volts DC, 8 AA Batteries

Setup & Configuration Prior to Activation

Some pre-planning is necessary to ready the ICRI for use. The following should be accounted for before placing the ICRI on-line:

Predetermine what the power source will be for the ICRI and verify that the cable or battery pack is available

Predetermine what brand and model of radios will be connected to the ICRI and that an “interconnect” cable for each radio is available

Office of Emergency Communications

Setup & Configuration Prior to Activation (Continued) Advise agencies that they will need to supply a “spare” radio,

for the radio interoperability, that the radio supplied must be known to operate properly and have at least one spare fully charged battery

Separate the interface radios Ensure a clear field of view Only connect agencies that need to interoperate Coordinate gateway usage

Memorandums of Agreement (daily operations) Communications Leader (COML) (per incident)

Interfacing non-standard radios, the radio’s owning organization should provide: Interface cables Spare batteries and/or chargers Radio configuration/channel list

Setup & ConfigurationICRI Operation

After connecting a power source to the ICRI, turn it on so that power up and input voltage can be verified When using a DC source voltage between 6.5 and 7.4 volts

neither the OK nor the LOW voltage LEDs will light, but the ICRI will be function

Connect the radio interface cables to the ICRI (All five ICRI radio interface connections are electrically identical)

Connect the radio interface cables to the radios Be sure the radios are on the channels assigned to the

interoperability function Turn on the radio

Creating & Breaking Patches ICRI

Select the talk-group the radio will be assigned to and place the switch above the associated port in the designated position

NOTE: The center position of the switch places any item connected with the associated port into a “NO CONNECTION” conduction without physically disconnecting the device from the ICRI.

If used, connect the telephone and handsetNOTE: For initial setup and troubleshooting purposes, C-AT

recommends the use of the local handset or headset Select the talk-group the telephone and/or handset will

be associated with. Turn on the telephone.
