Aritech DT2073 Addressed Heat Detector (Class A1/A2/B, 7-Segment Display)

The DT2073 is an addressed temperature detector operating on the 2000 series protocol; it operates in Class A1, A2, or B depending on control panel configuration. The temperature rise rate algorithm allows alarm escalation before the fixed trigger threshold is reached — this is the time gained in a rapidly developing fire. The 7-segment display on the unit reads device status on site: fault, pre-alarm, maintenance warning (CleanMe), and deactivation are each displayed separately, so the maintenance team understands the situation without going to the control panel.
