Description
The QR Systems AR-1 wired addressable expander connects conventional fire detectors, buttons and other devices with a dry-contact output to a QR Systems addressable analogue fire alarm system and transmits alarms to the control panel. Up to three detectors connect to the expander loop, and the line to the dry-contact device can be up to 10 m long. The expander is an addressable device that occupies one slot on the panel and is powered from the PLS line: 0.17 mA in standby and 0.18 mA with a loop short circuit. An LED indicator shows the device state and operating mode. It is used with the control panel and the KS-02-250 system controller, and its 40×56×20 mm size and 30 g weight let it fit in a standard junction box.
Advantages
- Up to 3 conventional detectors in one addressable point — ordinary detectors work in an addressable system
- Dry-contact inputs — connection of buttons, actuating and technical systems with alarms sent to the panel
- Powered from the PLS line, 0.17 mA — no external supply needed
- One address slot — economical use of address space
- 40×56×20 mm and 30 g — fits in a standard junction box
- Operating temperature from −25 to +55 °C — installation in various climatic conditions
Applications
- Migrating conventional fire detectors to a QR Systems addressable analogue system
- Connecting buttons and devices with a dry-contact output
- Monitoring building and technical systems through the fire alarm system
- Small rooms and zones with 1–3 detectors
- Step-by-step fire alarm upgrades keeping the installed detectors
