Section 2

– GENERAL OPERATION

The

VDOT-H2

heat detector initiates an alarm in response to both 8.3 °C (15 °F) rate-of-rise temperature or a 57 °C

(135 °F) fixed temperature alarm point.

The

VDOT-H2-H

initiates an alarm in response to 83 °C (181 °F). Heat detector incorporates a highly linear

thermistor circuit, with the thermistor mounted externally. The specially designed cover protects the thermistor while

allowing maximum air flow. The thermistor circuit produces a voltage proportional to temperature which is scaled, and

transmitted as a digitally encoded value to the control panel.
