Description
The QR Systems KS-02-250 controller manages a segment of an addressable fire detection, fire suppression, smoke extraction and notification system, as well as the auxiliary building and process equipment involved in fire safety. Up to 250 addressable devices connect to the controller over a ring addressable loop; loop integrity and the health of the addressable devices are monitored automatically. The controller is used with the PPK-02-500 control panel: up to 32 controllers operate in one panel's network, so the system's address capacity grows segment by segment. Two freely programmable inputs/outputs, two controlled dry-contact outputs and two supervised outputs serve to control voice and light notification, fire suppression and smoke extraction. A solution for design and installation companies building QR Systems addressable fire detection on large sites in Tashkent and Uzbekistan.
Advantages
- Ring addressable loop, 2 lines up to 800 m — addressable devices at a distance from the controller with loop integrity monitoring
- Own address space for 250 devices — a separate system segment with its own detectors and modules
- Up to 32 controllers in a PPK-02-500 network — system capacity grows segment by segment
- Automatic health monitoring of addressable devices — faults are visible at controller level
- 2 programmable inputs (line supervision 4.5 mA), 2 dry-contact outputs up to 2 A and 2 supervised outputs up to 0.45 A — control of notification, fire suppression and smoke extraction
- Compact housing 160×125×36 mm, up to 0.3 kg, current consumption up to 0.15 A — fits in cabinets and floor risers
Applications
- Addressable fire detection segments in multi-storey buildings and business centres
- Shopping centres and warehouses with smoke extraction and fire suppression systems
- Distributed sites where the address capacity of the PPK-02-500 is extended with controllers
- Control of notification and building equipment within the segment area
- Residential complexes, hotels, educational and medical institutions
