As the name suggest this is a modular system that could be implemented on any Control and Management System.
The system are programmed and optionally controlled by a PC based software package, using interfacing ranging from USB to Ethernet to RS485 interface modules.
A variety of control modules are available, that could be implemented for Advanced Access Control, Building and Property Management or Event or Process Control and Management.
The system is extremely versatile and flexible and could be successfully implemented in any environment.

The Leaky Feeder is essentially a extended antenna that is fed through the operating area of a underground or tunnel system for normal hand-held VHF or UHF radio communication to reach into these areas.
The system consist of a Base Station where the Radio Repeaters and Head End Combiner are located for the injection and reception of radio signals into and out of the Leaky Feeder Cable that is spread through the operation area. The Head End Combiner also inject power onto the Leaky Feeder Cable to power In-Line equipment.
The radio signal radiated from the Leaky Feeder Cable and also the signal that bleeds into the cable from hand-held radios must be amplified and re-injected into the cable to ensure proper operation, and this is done by connecting a Mini In-Line Amplifier every 350 to 700m of Leaky Feeder Cable.
The system also used connection and power injection modules and these range from Junction Boxes, 3Way Splitters, 4Way Splitters, Power Couplers. These modules are available as Standard Equipment and also a Econo-Range of equipment. The only real difference between the Standard and Econo-Range is the Enclosure and Connectors used and the Econo-Range do not have all the indication and trip facilities available on the Standard Equipment.
