Description
The QR Systems RR-02-250 wireless range extender increases the radio range between the addressable analogue fire alarm control panel and the wireless devices of a QR Systems fire alarm system, and also connects wireless devices to the KS-02-250 system controller. The extender is linked to the panel over the PLS wired addressable line and occupies one address slot, while it communicates with wireless detectors and sounders over the RF 868 MHz radio channel. Communication is two-way with delivery confirmation; the signal is encrypted with the XTEA 128-bit algorithm across five frequency channels. A built-in short-circuit isolator protects the PLS line, and the Test button and tamper switch simplify servicing. Up to 15 extenders can operate in one PLS line.
Advantages
- RF 868 MHz radio channel, up to 900 m in open terrain — wireless detectors and sounders where cabling is difficult
- Two-way communication with delivery confirmation — the panel knows the command reached the device
- XTEA 128-bit encryption and 5 frequency channels — protected link with automatic fault monitoring
- One address slot and up to 15 extenders per PLS line — radio segments scale within a large system
- Built-in short-circuit isolator — a short on one section does not take down the PLS line
- Test button, tamper switch and status LED indication — quick checks during installation and servicing
Applications
- Wireless segments of a QR Systems fire alarm system where cabling is difficult
- Historic buildings, museums, leased premises with finished interiors
- Extending radio coverage to remote parts of a site
- Connecting wireless devices to the KS-02-250 system controller
- Adding wireless components to a wired system in stages
