DAS-SHD-C324 CONVENTIONAL MULTI-SENSOR SMOKE AND HEAT DETECTOR
- A microchip samples in real time and processes the data to calculate smoke density and ambient temperature, ensuring fast and accurate alarms.
- Compensation for drift caused by dust accumulation, temperature and humidity helps minimize false fire alarms.
- The detector contacts are non-polarized, which simplifies installation, wiring and maintenance of the system.
- The electronic circuit board is conformally coated in 3 layers against moisture and corrosion and combined with 304 stainless-steel contacts, so the device operates reliably even in environments with acid or alkali vapors or high humidity.
- The photoelectric smoke detector features an intelligent smoke sampling chamber that keeps out insects and dust, extending the cleaning and maintenance interval of the detector to up to 2 years.
- Can be connected to a 5 VDC remote fire indicator lamp
