Technical details

Sigma NX Control L is a control unit designed for managing small Gas Safety Systems.

Its main purpose is to control, integrate, and continuously monitor all connected devices, including detectors and signalling devices, withing a single, cohesive system. Based on device readings, the unit automatically controls acoustic and optical signalling as well as actuating devices when a hazard is detected.

The Sigma NX Control L unit is equipped with a unique display that enables an immediate and clear assessment of the status of the entire Gas Safety System at a glance, without the need to analyze data on the screen. This module therefore provides GasOK functionality.

Key features:

  • Built-in system optical indicator: The Sigma NX Control L unit is equipped with a unique display that enables an immediate and clear assessment of the status of the entire Gas Safety System at a glance, without the need to analyze data on the screen. This module therefore provides GasOK functionality.
  • Supported devices: From 1 to 20 gas detectors and up to 4 signaling devices on a single shared RS485 bus.
  • Signaling zones: Supports 3 operating zones – 2 fully configurable user zones and 1 built-in master zone that includes all devices in the system.
  • Configuration: Configuration of the unit and connected devices is carried out using dedicated PC software.
