DURPARK AND DURPARK RS485 DETECTORS

DURPARK and DURPARK RS485 CO/NO₂ Gas Detectors

Advanced Electrochemical Detection for Car Park Safety

DURPARK and DURPARK RS485 gas detectors are high-performance devices engineered to monitor carbon monoxide (CO) and nitrogen dioxide (NO₂) levels in enclosed spaces such as parking facilities. Designed with precision electrochemical sensors, these detectors offer long sensor life, minimal maintenance, and reliable gas detection for enhanced safety.

Two models are available:

• DURPARK (3-wire addressable format)

• DURPARK RS485 (4-wire RS485 format), compatible with DURGAS and DURPARK control systems.

These detectors are equipped with microprocessor-based signal processing and auto-calibration capabilities, ensuring stable and accurate readings across a wide environmental range.

Features

• Advanced electrochemical sensing technology for CO and NO₂

• Two communication formats: 3-wire addressable or 4-wire RS485

• Automatic gain and zero calibration algorithms for simplified maintenance

• Internal CO sensor verification system without gas application

• Environmentally safe CO sensor electrolyte

• Factory-calibrated for accurate measurements

• Seamless integration with DURPARK and DURGAS control panels

• Separate models for CO and NO₂, each optimized for their target gas

• Long sensor life: up to 5 years for CO and 3 years for NO₂

• Compact ABS housing with easy wall-mount installation

• Dual-level installation: 1.8–2 m for CO, 40–50 cm for NO₂
