Introduction
The VDOT-PYH3 has two operating modes for heat detection either rate-of-rise and fixed heat at 57 °C (135 °F).
The detector incorporates a heat sensing thermistor, mounted outside of smoke chamber, with the high linear circuit.
The specially designed cover protects the thermistor while taking airflow.
Detector address is selectable from the range of 1 to 254, and programmed by using the VDOT-AD2 handheld address-setting tool.
A remote LED indicator can be connected to the detector Terminal 3 (RIL) directly.
