Non-Aspirated Systems / Automatic Water Shut-Off Valves / BREEAM
A revolutionary new refrigerant gas sensor for occupied spaces and the next generation in sensor technology for a better and safer environment

AT-SRG sensor for refrigerant gas

  • Replaces the AT-G-SENSE and AT-G-ALERT
  • 15+ year sensor lifetime means low lifetime cost of ownership
  • Compact UK single gang electrical socket size for an aesthetically-pleasing, non-intrusive appearance
  • Simple installation, set-up and commissioning as no calibration required
  • Easy system testing with a plug-in alarm emulation module (no gas required)
  • Immune to poisoning – the sensor is not affected by hairspray, deodorants or other non-target gases
  • Multiple alarm outputs, audible and visual, centralised and BMS monitoring
  • Automatic temperature and humidity compensation
  • Mains and low voltage power options
  • Easy sensor replacement (plug & play) with interchangeable sensor heads for different gas types
  • Helps achieve BS EN378: 2016, BREEAM Pol 01 and F-GAS
