Door Contacts:DC-15/DC-15SL

Distinguished by its long battery life, the lithium battery-powered DC-15SL Series monitors the opening/closing of doors and windows and alerts the security system to potential dangers. Slimmer and shorter than the original design, the DC-15SL models blend naturally into home décor and become less noticeable for the intruder looking to destroy the sensors. The models’ extension terminals for connection to wired devices enable them to serve as universal transmitters. This series’ powerful new model the DC-15SL-F1 adopts the latest RF technologies to deliver long RF range and fast signal transmissions. The original DC-15 Series features standard battery life.
