Type: Addressable optical smoke detector
Purpose: The DOR-4046 optical smoke detector is designed to detect visible smoke, which accompanies most fires. It enables early fire detection at the initial stage, when materials begin to smolder, long before open flames appear and temperatures rise significantly. The DOR-4046 is an analog device with automatic self-compensation of sensitivity, maintaining constant sensitivity even as dirt accumulates in the measurement chamber or as pressure and steam condensation change.
Co-operation: The DOR-4046 can only operate in lines/loops of all addressable fire alarm panels of the POLON 4000 series.

The DOR-4046 features an internal short-circuit isolator and works with the non-addressable mounting base G-40. Additional optical signaling for one or a group of detectors can be created by connecting the WZ-31 indicator. The detector uses the principle of measuring infrared radiation scattered by smoke particles (aerosol) entering the optical measurement chamber, which is shielded from external light. The photodiode inside the chamber detects scattered infrared light only when smoke is present. Thanks to automatic compensation, the detector maintains constant sensitivity even as contamination increases or environmental conditions change. If the full range of auto-correction is exceeded, a service alarm is sent to the control panel without losing fire detection capability. The detector's microprocessor and dedicated software ensure fast analysis and minimize false alarms. The DOR-4046 can transmit measured analog fire factor values and additional information such as service status, internal circuit damage, and short-circuit isolator activation. Alarm status is indicated by red flashes of a two-color LED, while faults and technical alarms are indicated by yellow flashes. The address is programmed automatically from the control panel and stored in the detector's memory.
