Zeta Simplicity CO 8 Zone Addressable Carbon Monoxide Panel (126 Devices) (S126/CO)

The Zeta Simplicity CO S126/CO is an 8 zone analogue addressable carbon monoxide detection and ventilation control panel. It uses the Standard Zeta addressable protocol and works with Zeta CO800G addressable CO detectors. Each zone continuously displays the highest CO concentration in that zone in ppm on the LCD, and the panel drives ventilation equipment through interface modules at pre-set levels, raising an alarm if the concentration keeps rising.

Key features

• 1 to 8 zone analogue addressable CO monitoring system
• Devices connected as a single loop or as separate radial circuits
• Three adjustable global thresholds: first ventilation, second ventilation and alarm (defaults 50ppm, 75ppm and 100ppm)
• Individual or common-acting ventilation relays via ZIOU interface modules
• Zone disablement and test modes
• Supports loop-powered sounders and 2 conventional sounder circuits
