Object
Body Print Chamber Fire Sensor
A small electronic device mounted near the Body Print Chamber's entrance, its metallic housing painted the same institutional gray as the facility's other warning systems. The red warning light pulses once as the Doctor's fingers brush its panel, and the shrill electronic warble of its alarm cuts through the sterile air with mechanical precision. When activated, it broadcasts its signal not through visible panels but through the same emergency grid that routes alerts to control terminals across the Zygon infiltration site.

Purpose
Electronic fire safety detector designed to trigger audible and signal-based alerts when sensing abnormal heat or smoke, repurposed by the Doctor to create coordinated false alarms across the Zygon-controlled facility.
Significance
Transforms from a passive monitoring device into a tactical tool, the Doctor's manipulation exposes the fragility of Zygon infiltration by exploiting existing human systems against them. Its false activation accelerates the confrontation, forgoing stealth to force the disguised Zygons to reveal their true nature prematurely.
