Why fire signal cannot be cleared on GST C-9105R Security Sensors?
- S
  Sean AllenAug 3, 2025
  If the fire signal on your GST Security Sensors cannot be cleared, it might be due to several reasons. There could be obstructions on the optical pathway between the detector and the reflector, or the angle of the optical pathway may have changed and needs realignment. Alternatively, the emitting diode, its circuit, the photodiode, the amplifying circuit, the relay, or the control circuit could be damaged. If the problem is due to obstructions or angle changes, commission the device again. If it's due to damaged components, replace the component with the problem.
