Alula Environmental Sensor (Flood, Freeze, Heat)

The Alula RE619 is a Connect+ encrypted, tri-mode environmental, wireless home disaster sensor. The RE619 sensor is designed to detect flood/moisture, freeze and overheat conditions. The RE619 flood alarm will trigger when liquid rises 0.040 inches above the sensor bottom. The flood sensor checks for moisture every 5 seconds and needs two positive moisture checks to send a flood alarm (test mode: every second when cover is off). The RE619 freeze alarm will activate, for furnace failure, when the temperature drops below 40°F. The overheat alarm will trigger, for furnace runaway or air conditioning failure, when the room temperature rises above 100°F.
