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.
