- oil or gas-fired boiler plants (with boilers without flue gas flow sensor);
- kitchens and bathrooms equipped with gas appliances e.g. cookers, ovens, water heaters (with open combustion chamber);
- rooms containing gas appliances such as: valves, gas meters, cylinders, tanks, gas pipes (basements, corridors);
- rooms with a fireplace, or coal or wood-burning stoves;
- rooms heated by portable propane-butane stoves;
- domestic garages;
- solid fuel-fired boiler rooms;
- school laboratories;
- rooms with air conditioning or refrigeration equipment (freon leaks).
- microprocessor-controlled;
- external siren control;
- can work with many devices;
- the detectors are covered by a 3-year warranty;
- all detectors are calibrated in our own GAZEX Calibration Laboratory operating in accordance with PN-EN ISO/IEC 17025 standard (PCA accreditation no. AP150).
The DK-1 detector is manufactured in the following versions:
• DK-1 - power supply ~ 220 V, - the basic version, without control terminals,
• DK-1.S - power supply ~ 220 V, with terminals for connecting an additional siren DK-S3 (95 dB),
• DK-1.T - power supply ~ 220 V, with trans-optical terminals for connecting alarm (emergency) systems of various types,
• DK-1.P - power supply ~ 220 V, with a transmitter output for controlling electric cranes and fans,
• DK-1.A - 12 V power supply, for installation in camping trailers, yachts, or for direct integration into the general alarm protection system of the premises (object). Arbitrary combinations of conclusion types are possible.
• DK-1 - power supply ~ 220 V, for automatic control of the faucet cuts off the gas supply to the system; available options: -Z/S, Z/T, -Z/ST or -Z/W (with a conclusion that allows the development of the system with additional detectors).
