ELK319DR
Keep tabs on movement into or through your home with the Elk Recessed Door Sensor. This two-part recessed wireless door sensor is designed for discreet indoor entry monitoring. The sensor mounts on the inside edge of a door frame and the door itself. When the door is opened or closed, the sensor sends an alert signal to a connected receiver. The sensor can also deliver alerts when the batteries are low or when the sensor is being tampered with. The sensor is virtually invisible when the door is closed.
This sensor is compatible with receivers and panels that use the 319.5MHz radio frequency, including Elk's 319 series well as ITI/Interlogix protocol receivers and panels.
