AIE-E Ionisation Smoke Sensor
Model AIE-E is an Ionisation Sensor, which is fully compatible with Hochiki’s ESP Analogue Addressable Protocol.
A single radioactive source within the AIE-E ionises two chambers, which allows a small DC current to flow between the electrodes in each chamber. Smoke can freely enter the outer chamber whilst the inner chamber is virtually sealed. Smoke entering the outer chamber causes a reduction in the DC current, the imbalance between the two currents is proportional to smoke density, which is filtered and transmitted as the analogue value
The threshold on the AIE-E can be adjusted to compensate for contamination by utilising the built in test facility. Features
