Air in the dual sensing chambers is irradiated to produce ions that travel to the positive and negative electrodes, creating a current flow. As smoke enters the outer chamber, the flow drops and the voltage increases. The detector will then enter the alarm state and the indicator LED lights up.

An intergrating ionisation detector, suitable for use in areas where transient high levels of smoke may be expected 

 

The detector has a moulded self-extinguishing white polycarbonate case withwind resistant smoke inlets. Nickel plated stainless steel wiper contacts connect the detector to the base.Inside the detector case a printed circuit board has the ionisation chamber mounted on one side and the signal processing electronics on the other.
