Global fire systems business Advanced has released a new intelligent carbon monoxide (CO) detector and sounder base that works with the company’s Axis AX fire system to provide standalone CO detection with plug-in fire multi-detection capabilities in one SLC device. The device is an electrochemical sensor capable of detecting three levels of carbon monoxide (70,150 and 400 PPM), with superior rejection of transient signals. The built-in sounder can provide either a temporal 4 (CO event) or temporal 3 (fire alarm event) signal, with the fire alarm event having the highest priority. The Axis AX fire panel can activate multiple CO sounder bases in a facility when CO is detected, providing the appropriate synchronized evacuation tones throughout an area or the entire facility. Standard Axis AX photo, ion, heat and multi sensors can be easily locked in.
