DD/AP

DD/AP digital detectors are designed for continuous monitoring of methane, propane-butane, carbon monoxide or Freon indoors. Exceeding the preset concentration values produces an optical alarm signal, a change of status of the output terminals and activates the buzzer.

The detector has a removable module with the intelligent semiconductor sensor, which facilitates maintenance and lowers operating costs.

Field of application

  • Hotels, offices, public buildings
  • Household boiler rooms burning natural gas and propane-butane gases
  • Rooms with A/C equipment

Features

  • long life, semiconductor gas sensor;
  • ease of installation and connection (detachable terminals);
  • built-in acoustic buzzer;
  • sensor in removable, intelligent module;
  • built-in microprocessor control = reliability, stability, thermal compensation system, alarm history;
  • stylish housing for wall mounting (cable entry from the plaster or mounting to a typical Ø60mm, flush-mounted box with screws at the edge);
  • all detectors are calibrated in our own GAZEX Calibration Laboratory operating in accordance with PN-EN ISO/IEC 17025 (PCA accreditation No AP150).

Detection of substance/property in other areas or other substances/properties is possible = special execution, requires consultation.
In special cases, it is possible to select the detector parameters for a specific application = required analysis of the conditions of use.
