RRP £2,606.00 excl. VAT

The SLR 5500 is the natural replacement to the previous DR3000 radio repeater, this updated model now sports a smaller size (1U) and is designed for indoor use only. The new unit is future proofed in many areas, 15 times more memory, 10 times more processing, 12 times more storage and I/O options. The repeater is designed for either desktop, rack or wall mounting. The choices of operations are full ranging, from simple analogue operations to Capacity Max integration (with license keys).

The unit is rated at 100% duty cycle with field replaceable modules, this is an improvement over the “two mobile in a box” approach. Battery backup options and alarms are wide and varied, networking options are catered for IPSC, Capacity Plus, Linked Capacity Plus and Capacity Max.

The product is very versatile and can aid analogue to digital migration strategies with Dynamic Mixed Mode operation. 3rd party interfacing is also available for CAD packages such as TRBOnet Enterprise and TRBOnet PLUS, this reduces the need for local control/master stations.

What we think

Jason from the Service Team: “The main work horse of any serious radio system that uses a repeater. Its essential for reliable robust operations with a great pedigree. Pros – amazing receiver and transmitter performance, great feature set and flexibility, reliability has been great with no real issues experienced. Cons – its heavy and you certainly know where the money is being put especially when compared to other manufacturers. It’s the core item to any radio system that’s needs a repeater unit.
