Siemens 500-081806

The Siemens 500-081806 is an ionization detector designed for precise smoke detection applications. Operating within a voltage range of 2.5 to 5.8 volts, this detector offers an obscuration sensitivity of approximately 1.5% per foot, ensuring reliable identification of smoke particles. It functions effectively in temperatures ranging from 23 to 100 degrees Fahrenheit. This model has been succeeded by the OP121 combined with the DB-11 base, but the 500-081806 remains a trusted option for certain setups. BSP Automation provides this ionization detector as part of their extensive range of industrial automation components.
