Monitoring and Alarm Systems

• On-board diagnostics continuously monitor sensors to ensure proper performance
• Control Setpoint sets cabinet temperature, Cabinet Temperature displays the temperature
• Automatic Incident Monitor (AIM) identifies temperature deviation due to power or temperature failure
• Time Delay feature delays restart after power failure
• Voltage Buck/Boost corrects line voltage into the unit
• Low Voltage Surge Protection minimizes voltage spikes
• Life-Guard Alert monitors compressor performance, automatically adjusts to internal and external conditions
• Clean Filter, Alarm Battery Low, and Voltage indicators
• Battery backup supplies control panel in case of power failure
• Key-operated main power and alarm switch locks temperature and alarm setpoints
• Audible/visual power and temperature failure alarms automatically activate during a temperature deviation
• Extreme Ambient Alert warns if room temperature may affect performance
• Alarm Test simulates temperature alarm condition
• Alarm Reset mutes audible alarm and resets AIM
• Remote alarm contacts for external alarm/monitoring system
