Description
The Velox 40920 Intelligent Analogue Addressable Optical & Heat Detector is engineered to maintain safety integrity and deliver comprehensive early warning fire detection across commercial buildings, educational facilities, healthcare institutions, hotels, and data centers. By integrating advanced optical scatter chamber technology with a precise thermal thermistor element, this multi-criteria detector evaluates both smoke density and rapid temperature changes simultaneously. Designed for seamless operation on Velox analogue addressable fire alarm loops, it utilizes intelligent micro-processing algorithms to discriminate between actual fire smoke and ambient dust or steam transients, providing exceptionally low false alarm rates and reliable life-safety monitoring.
Features
- Dual optical and heat sensing technologies provide superior response across a broad spectrum of smoldering and fast-burning fires
- Advanced false-alarm rejection algorithms effectively eliminate nuisance alarms caused by dust, steam, or air turbulence
- 360-degree visible dual-color LED indicators give immediate local visual confirmation of system status and alarm conditions
- Fully software-addressable design simplifies commissioning and eliminates manual DIP switch or rotary setting errors
- Direct loop-powered communication integrates seamlessly into Velox intelligent fire alarm panel networks
