G-TECTA™ Cellaguard™ is a carbon dioxide (CO2) or a carbon dioxide and oxygen (O2) fixed monitoring system, designed to monitor gas levels in a confined space such as a beer cellar. The Cellaguard system consists of a wall mounted base station, housing the gas monitoring system, and is normally supplied with one repeater unit to be located in a safe position outside the confined space area. The G-TECTA Cellaguard is normally supplied with one repeater unit. The repeater unit mimics the alarms, fault alarm, power indicator, mode button and sounder on the base unit. A series of up to 4 repeater units can be connected together at distances of up to nine metres per repeater. This allows the user to position the alarm system warnings in visible and convenient locations. Two versions of the G-TECTA Cellaguard are available:
Version 1: a carbon dioxide monitor only, which looks for rising CO2 gas levels in the confined space.
Version 2: a combined sensor system which monitors both rising levels of carbon dioxide and falling levels of oxygen.
Two alarm relays, which can control external visual or audible alarms or ancillary equipment such as ventilation fan.
Simple to install, using a mains power supply, and designed for one-man installation.
Alarm levels are factory set and the relays are ‘fail- safe’ to ensure the alarms will activate if the power supply fails.
