Multi-Criteria
The Discovery UL Multi-Sensor Detector consists of photoelectric smoke and thermistor temperature sensors which give a combined signal for high immunity to false alarms.
- Contains both a photoelectric sensor and thermal sensor
- Used as a general-purpose sensor that responds well to a wide range of smoke/fire types
- Provides numerical temperature readings
- Supports Overwatch Custom Thresholds
- Dual status LEDs for 360 degree indication
- Enhanced false alarm management
- Five operating modes for customized fire detection
- Drift compensation to ensure constant sensitivity
- A great alternative to Ionisation detectors
- Model 58000-750APO. This product is obsolete, but is supported by the Overwatch panels for back-fit applications
Photo-Electric Smoke
The Discovery UL Photoelectric Smoke Detector uses a “distributed intelligence system” to quickly detect fire while effectively managing false alarms.
- Five response modes for adaptability to changing environments
- Resists steam and cigarette smoke
- Drift compensation to ensure constant sensitivity
- Supports Overwatch Custom Thresholds
- Dual status LEDs for 360 degree indication
- Model 58000-650APO. This product is obsolete, but is supported by the Overwatch panels for back-fit applications
Heat
The Discovery Heat Detector features a low air flow resistance case and a single thermistor to sense the air temperature around the detector.
- Reliable fire detection in areas with a very wide temperature range from -40°C to +70°C
- Five operating modes suitable for a range of application temperatures
- Supports Overwatch Custom Thresholds
- Provides numerical temperature readings
- Ideal for environments that are dirty or smoky under normal circumstances
- Dual status LEDs for 360 degree indication
- Drift compensation to ensure constant sensitivity
- Unaffected by wind and atmospheric pressure
- Model 58000-450APO. This product is obsolete, but is supported by the Overwatch panels for back-fit applications
Ionization Smoke
The UL Discovery Ionization Smoke Detector incorporates an ionization chamber design using Americium 241R to irradiate the air in the smoke chambers. If smoke enters the chamber, the current flow is reduced leading to an alarm.
- Responds well to fast burning, flaming fires
- Operates in a variety of environments
- Resilient to dust
- Multiple sensitivity settings
- Dual status LEDs for 360 degree indication
- Drift compensation to ensure constant sensitivity
- Model 58000-550APO. This product is obsolete, but is supported by the Overwatch panels for back-fit applications
