Description
The QR Systems RA-30 interface repeater extends the length of CAN interface lines and joins and branches them within a network of QR Systems fire alarm panels. The device supports bus, ring and star connection, so the panel network follows whatever topology suits the site. The repeater has two CAN interfaces, terminator switches, programming connectors and LED indicators of data exchange. Up to four repeaters connect in series in one CAN line, and up to 30 repeaters operate in the CAN network in total; the repeater occupies 0 address slots. It is powered from DC 24 V, draws no more than 0.047 A and operates from −25 to +55 °C — a solution for installation companies linking QR Systems panels on large and distributed sites in Tashkent and Uzbekistan.
Advantages
- Extension of CAN lines — panels can be placed further apart while keeping network communication
- Joining and branching of lines — one CAN network from several segments of a building
- Bus, ring and star topologies — a network that fits the site layout
- Up to 4 repeaters in series and up to 30 per network — scale for a large site
- 0 address slots — the system's address capacity stays with panels and detectors
- Current consumption up to 0.047 A, 115×90×40 mm housing, up to 0.12 kg, −25…+55 °C — a compact module with a temperature margin
Applications
- Networks of QR Systems panels in multi-storey buildings and business centres
- Distributed sites of several buildings linked over CAN
- Branching the CAN line to floors and wings of a building
- Retail, warehouse and industrial complexes with several panels
- Unheated technical rooms with temperatures down to −25 °C
