Description
The QR Systems IP 101-102-A1R (white housing) addressable analogue fixed-temperature and rate-of-rise heat fire detector detects fires accompanied by a temperature increase in the monitored space and sends a Fire signal, as well as signals about its own technical condition, to QR Systems panels or controllers. The detector identifies a fire in two ways: when the maximum temperature in the +54 to +65 °C range is reached, and by the rate of temperature rise. Communication and power are over the wired PLS loop; the detector occupies one address slot and is detected automatically by the panel. The device measures the PLS voltage at its installation point and can be switched to service mode without losing its binding. Suitable for rooms where smoke detectors are impractical.
Advantages
- Two detection methods: maximum temperature and rate of rise — responds to both slow and rapid temperature increases
- Response temperature +54 to +65 °C — class A1R
- Generates Fire and Fault signals — the panel sees both the alarm and the detector's condition
- Automatic detection in the system — fast commissioning
- PLS voltage measurement at the installation point — loop diagnostics without additional instruments
- Current consumption no more than 0.24 mA in standby and 0.26 mA in Fire mode — low load on the loop
Applications
- Kitchens, boiler rooms and technical rooms where smoke and steam interfere with smoke detectors
- Garages and enclosed parking
- Production shops and workshops
- Storage rooms with dust or aerosols in the air
- Sites with a QR Systems addressable analogue fire alarm system
