Description
 

Model SD505-AIS Addressable Ionization Type Smoke Detector

The SD505-AIS has responsive, yet high operational stability for an extremely wide range of uses. The SD505-AIS can be used in areas where early warning of trouble from super-heated or flaming combustibles is expected.

The detector features automatic compensation for contamination and a simple detector sensitivity test procedure that can be run from the panel or remotely (using the IntelliKnight 5590 or 5595 software with a Windows TM based computer).

Operation
The SD505-AIS ionization smoke detector has two chambers: a sampling chamber and a reference chamber. Smoke or invisible combustion gases can freely penetrate the sampling chamber, but the reference chamber is virtually closed to prevent easy entry. With both chambers ionized by a single radioactive source, a very small current flows. Presence of visible smoke or invisible gases greatly influences the current flow in the sampling chamber, changing the voltage ratio between the chambers. This difference is amplified inside the detector. After reaching the critical level, the detector triggers into alarm.

The SD505-AIS includes a status LED which blinks approximately every 15 seconds, indicating that the head is communicating with the loop. The status LED lights continuously during the alarm period.
