ABSTRACT:
A carbon monoxide Monitoring System includes a control panel and remote alarm stations. The control panel is associated with a carbon monoxide monitoring unit, an emergency AC power pack and an alarm system. Each remote alarm station includes a visual-audio alarm system and a distress signal system. The carbon monoxide monitoring unit continuously samples the personnel air supply and if the CO reaches a pre-set concentration, it will provide a primary audio-visual alarm signal to a panel alarm for the control panel operator and to each individual remote alarm station, thereby giving warning of an excess of carbon monoxide gas in the air supply to the control panel operator and to the remote workers. In addition, if a worker at any remote station is in distress, he actuates his distress signal system which energizes the control panel alarm system. The control panel operator is alerted and takes whatever action is required. The AC emergency power pack will automatically provide AC power to the CO monitoring unit and to the remote stations, in the event the normal AC power supply is interrupted. This allows for fail-safe operation of the CO monitoring system in an emergency.
