Additional information

Main communication requirements of armored vehicles are radio/s, intercommunication system, and duplexer. One of the main considerations of the vehicles is arranging these systems as well as their easy operation for commander. All of the mentioned equipment is considered as an integrated system as follows:

Two radios in one case with proper dimension suitable to install inside every vehicle
The abovementioned two radios can be controlled via a remote control unit
In addition to the radios, Intercommunication system can be controlled via the remote control unit
There is no need for the operator for duplexer so that it is set automatically (considering status of the radios)
Infantry unit can be operated as a wired/wireless unit

Radios are operated in VHF frequency band with capability of ciphering and frequency hopping as well as transmitting/receiving voice and data.

Up to 6 crews can be supported by the intercommunication system. In addition, it can announce alarm sensors of the vehicle.

Radios of the system can be operated stationary as well as retransmission station.

Capabilities

Including two VHF-LB radios (in one case), intercommunication central unit, commander remote control panel, gunner terminal unit, 50 crew member terminal units, wireless/wire infantry terminal unit, automatic duplexer, and external loudspeaker for controlling, setting, and displaying the system communication status and establishing voice communication between the commander and intercommunication central unit
Connectable to one gunner, one driver, three crews, and one infantry
Establishing wireless/wire communication with infantry
Capability of establishing communication with automatic duplexer in case that an antenna is available on the vehicle
Capability of installing on various types of armored vehicles
Connectable to an external loudspeaker for propagating received voice from the radios
Capability of turning ON/OFF the system completely via a key available on the commander remote control panel
Capability of connecting vehicle’s sensors to the system and audio/visual displaying the activated sensors
Capability of establishing intercommunication between the crews
All of the crews can gain access to radio 1 due to the commander authority
Commander and gunner can gain access to radios 1 and 2
Capability of programming all of the system equipment externally
Capability of filtering various noises created due to the vehicle
Proper voice quality in all statuses
Easy troubleshooting
Easy operation
