Description
The QR Systems IP 212-104-S3 optical point addressable analogue smoke fire detector with light and sound alarm detects smoke in enclosed rooms of buildings and structures by measuring the optical density of the air, sends the signal to the fire control panel over the wired communication loop and at the same time warns people of a fire with light and sound signalling. The device combines a smoke sensor and a base with an alarm: the sensor is powered from the PLS loop, the base from a separate 24 V DC source; the detector occupies two address slots in the system. The alarm's sound pressure level at 1 m is no less than 85 dB, and the smoke channel sensitivity is 0.05 to 0.2 dB/m. The detector operates under the control of the panel as part of a QR Systems automatic fire alarm system, is installed indoors in places protected from precipitation and is designed for continuous round-the-clock operation.
Advantages
- Smoke detection and alarm in one housing — fewer devices on the ceiling and less installation work
- Sound pressure no less than 85 dB at 1 m plus light signalling — people in the room learn of a fire immediately
- Sensitivity 0.05–0.2 dB/m — early smoke detection
- Loop-powered sensor: no more than 0.17 mA in standby and 0.18 mA in fire — minimal load on the loop
- 24 V DC base: 4.6 mA in standby and 18.1 mA in fire — the alarm does not load the PLS loop
- Average service life 10 years, 60 000 h mean time between failures — long operation without replacement
Applications
- Hotels, dormitories and residential complexes — alarm directly in the rooms
- Offices, studies and meeting rooms
- Educational and medical facilities
- Retail and administrative buildings
- Rooms that need both a smoke detector and a local alarm in a QR Systems system
