Zeta Ionisation Smoke Detector

The dual chamber design is utilised to compensate for changes on atmospheric & environmental conditions
The Fyreye ionisation smoke detector incorporates a single radioactive source (Americium 241 < 0.7uCi) ionises two chambers which causes a small current to flow to electrodes in each chamber. One chamber is open to the atmosphere, the other one is sealed. Any smoke entering the open chamber will cause the DC current to drop. This current is compared to the constant current in the sealed chamber. The difference between these two values is monitored by the detector. If the difference is above the threshold level, the Detector will turn its LED on to signal a fire.
