The L-MC-SG is the latest in wireless multi-criteria detector technology. It is a fully intelligent device and compatible with all Argus wireless Translator and Expander modules. The detector is designed for open area protection and combines both dual-path smoke and heat detection technologies for improved performance, whilst maintaining the high levels of unwanted alarm rejection. Utilising well-proven adaptive radio signal processing algorithms ensure the highest levels of life safety and system reliability are achieved. An in-built magnet test allows easy activation to verify correct functionality and response. advanced dual-path optical chamber design, 8 year battery life, utilises standard low cost lithium battery technology, multiple smoke and heat sensitivity settings, bi-directional wireless communications, device identification tab.
