New: A brand-new, unused, unopened, undamaged item in its original packaging where packaging is.. Carbon-X CO2 Alarm System(CDA-1). The TrolMaster Carbon-X system provides critical monitoring of CO2 levels for up to 13 separate zones / rooms. The system can have both high level (up to 30,000ppm) alerts, as well as low level (5,000ppm) alerts. Both high and low level limits are user-adjustable to meet local regulations for supplemental CO2 use indoors. The Carbon-X system can also control various devices such as ventilation fans, dampers, main CO2 valves as well as to send a signal to the fire department by interfacing to the fire / alarm panel in the facility. Automatic shut-off of CO2 is accomplished by wiring the facility’s main CO2 solenoid in series with one of the system control modules. The settings for each of the devices connected to the system are user-selectable for easy customization. Each room monitored by the Carbon-X will also require an audio-visual alarm to alert the personnel to the level of CO2 in the area, and whether or not it is safe to occupy the area. The TrolMaster app can be used to remotely monitor the Carbon-X as well as to receive user-alert / notifications in the case of high CO2 levels are detected. The CDA-1 is the brain of the system. We are pleased to serve you. Item must be in original packaging. Thanks for shopping with Empire430.
