Senator 25

Product Overview

Senator 25 are easily the most sensitive smoke detectors available. Furthermore, when such a detector is applied to small volume enclosures or areas, the effective sensitivity of the system becomes proportionately greater. The benefit is the very earliest warning possible in the detection area.
