Honeywell's 5821 is a versatile wireless device that can be configured to operate as either a standalone temperature sensor and/or a remote temperature sensor or flood detector. It is ideally suited for a wide range of applications including bathrooms, laundry rooms and basements and is fully compatible with 2GIG control panels.
Features:
  • Five selectable temperature ranges to choose from (hot, warm, cold, refrigerate and freeze)
  • Remote Temperature Probe available (T280R) ideal for refrigerator and freezer monitoring
  • Flood detection with 470PB External Probe for a wide range of applications; including bathrooms, laundry rooms and basements
  • Up to 10 year battery life, which reduces user maintenance
  • Completely wireless, which greatly reduces installation time and maximizes placement options
  • Capable of monitoring cold (45° F) temperature and flood detection simultaneously
  • Case Tamper Protection
Sensor Parameters:
  • Cold Temperature Detector 45°F when temperature drops below 45°F for >10 minutes
  • Warm Temperature Detector 75° when temperature rises above 75°F for >10 minutes
  • Hot Temperature Detector 95°F when temperature rises above 95°F for >10 minutes
  • Refrigerator Failure Detector 42°F when temperature rises above 42°F for >30 minutes
  • Freezer Failure Detector 10°F when temperature rises above 10°F for >30 minutes
  • Flood Sensor - when 1/4" inch of water is covering the 470PB probe
