The upgraded 1800 monitoring system from Sensaphone has a new keypad display and enhanced audio output. The system detects problems such as temperature changes, humidity fluctuations, water leaks, power failure, carbon monoxide and carbon dioxide levels and smoke. When the system identifies a potential issue, it can immediately alert up to eight people with custom phone calls. The internal rechargeable battery backup provides 24 hours of continuous monitoring and alerts in the event of a power outage. Operators can obtain the status of each monitored condition at the installation site or remotely by telephone.
