Full range of features of the UNIPARK CO / NO₂ detection control unit for car parks

The UNIPARK control unit continuously monitors carbon monoxide (CO) and nitrogen dioxide (NO₂) concentrations in car parks, garages and underground facilities. It automatically controls low-speed and high-speed ventilation (LS/HS) according to configured thresholds, provides alarm and fault reporting, and includes a buzzer to signal threshold exceedances.

Gas concentrations, ventilation status and faults are displayed on a colour touchscreen. The control unit calculates 20-minute and 8-hour average concentrations and records data on a removable SD card, with the option of transferring data to a USB flash drive. RS485 or Ethernet communication enables integration with a Building Management System (BMS), depending on the configuration.

Key advantages of the UNIPARK detection control unit

  • Two versions to suit every site: UNIPARK Modbus and UNIPARK Pneumatic
  • Automatic low-speed/high-speed ventilation control (LS/HS): up to 30 ventilation commands, 3 programmable time slots, remote inputs/outputs up to 1,000 m
  • 5" colour touchscreen (7", 10" and 15" options available, with remote display capability) for monitoring measurements, alarms and faults
  • RS485 or Ethernet communication, using Modbus RTU or Modbus TCP/IP protocols
  • Measurement traceability: 20-minute and 8-hour averages, removable 2 GB SD card and USB flash drive data transfer
  • The UNIPARK control unit is available in two versions:

    • The Modbus version is designed for use with a network of TWIN CO / NO₂ dual sensors (up to 60 sensors, providing 120 measuring cells) and 4–20 mA analogue sensors. Each sensor is individually identified on the network, allowing individual concentration readings and rapid fault location. Calibration can be performed directly from the touchscreen or using an optional Modbus remote control.

    • The Pneumatic version operates with a network of sampling tubes and sequentially analyses up to 16 measuring channels from a single unit. It is particularly suitable for renovation projects, as it can replace an existing aspirated detection control unit while retaining the existing sampling tubes, provided they are in good condition and compatible.
