Description
The QR Systems AMR-4 addressable expansion module connects conventional fire detectors to a QR Systems addressable analogue system, controls notification and building systems, and reports the state of every loop and output to the control panel. Four alarm loops connect to the module, each with up to 32 conventional detectors (smoke, heat, manual) whose standby current is no more than 45 µA. Four freely programmable 24 V outputs supervised for open and short circuit drive sounders and light indicator panels, while a dry-contact relay up to 250 V / 2 A starts fire suppression or smoke control or shuts down ventilation. The module operates over the PLS wired addressable line with the addressable analogue fire alarm control panel and with the KS-02-250 system controller, occupying 10 address slots. The board carries LED indicators, Test and Reset buttons and a tamper switch.
Advantages
- 4 loops with up to 32 detectors each — conventional detectors work in a QR Systems addressable analogue system
- 4 outputs 24 V ± 20 % up to 0.45 A supervised for open and short circuit — sounders and panels with line integrity monitoring
- 250 V / 2 A dry-contact relay — starting fire suppression or smoke control, or shutting down ventilation
- Detailed information on each loop and output at the panel — a fault is located down to the specific line
- DC 24 V ± 20 % supply from main and standby sources, no more than 50 mA excluding outputs
- Test and Reset buttons, LED indication and tamper switch — checks and servicing on site
Applications
- Migrating conventional loops to a QR Systems addressable analogue system
- Notification control: sounders and light indicator panels in the loop area
- Starting fire suppression and smoke control, shutting down ventilation on panel command
- Sites with many conventional detectors: warehouses, production facilities, educational buildings
- Expanding a system based on the KS-02-250 controller
