A range of addressable detectors with an electrochemical sensor, specially designed for car parks and small installations. Two gas models (CO and NO₂), each in a 3-wire (proprietary addressable protocol) or 4-wire RS485 version, compatible with the DURPARK and DURGAS control panels respectively.
Technical Specifications
| Technology | Microprocessor and electrochemical sensor |
| Supply voltage | 9–15 V DC |
| Consumption | 14 mA standby / 24 mA in alarm |
| Sensor life | >5 years (CO), 3 years (NO₂), virtually maintenance-free |
| Automatic calibration | Software zero/gain algorithm; CO sensor sensitivity check without applying gas |
| Operating temperature | -10…+60 °C, relative humidity 5–90% (non-condensing) |
| Protection class / material | IP20 / ABS housing |
| Communication | 3-wire, proprietary addressable protocol (1–16) or 4-wire RS485 (DURPARK RS485) |
Key Features
- Environmentally friendly electrolyte formula in the CO sensor, no leak risk
- Low cross-sensitivity to interfering gases (ammonia, CO₂, chlorine, hydrogen — see cross-sensitivity table in the datasheet)
- Addressable — up to 16 detectors per line
- Compatible with the new DURPARK (3-wire version) and DURGAS (RS485 version) panels
Variants
