The Thermalarm III uses sealed magnetic switches to trigger an alarm condition. The Thermalarm III features a contact that will close or open upon the temperature exceeding the high or low temperature alarm set-points, activating an alarm.

Features/Advantages:

• Corrosion resistant
• Simple set-hand adjustment
• Quick to respond to temperature change
• Works with most alarms

Placement: The Thermalarm’s temperature sensor is included in the unit, so placement of the Thermalarm should be at the site where you wish to monitor the temperature.

Temperature Alarm Set Points: To set the temperature alarm set-points, move the red “set” hands by moving the red knobs at the bottom of the unit to the desired high and low set-point making sure the temperature indicating hand (black) is between the two red set hands. You should have a five to ten degree difference between the normal temperature and your alarm set-points.
