Once the fire is out and the smoke is gone, the detection chamber clears, the ions travel back and forth between the electrodes as before, the circuit shuts down, and the alarm stops sounding.You can see an example of an ionization detector, opened up, in the photo below:...

Smoke alarms are not to be used with detector guards unless the combination has been evaluated and found suitable for that purpose. All these Smoke Alarms are designed to provide early warning of fires if located, installed and cared for as described in the user’s manual, and if smoke rea...
In areas where a 20-foot (6 m) distance is not possible – in mobile, or smaller homes, for example – it is recommended a smoke alarm to be placed as far from these fuel-burning sources as possible. The placement recommendations are intended to keep a smoke detector at a reasonable ...
A fire and smoke detector utilizes a statistical analysis of the near infrared radiation incident on it. The spectral radiation intensities incident on the fire detector are continuously measured at t
