Spec Data Sheet Button

Ajax DoorProtect Plus White is a Magnetic Opening Detector with Tilt and Shock Sensor that notifies you of the first signs of intrusion into the room through the door or window. It is installed even on roof windows which can be left open when leaving the house.

Not only can the DoorProtect be used for security reasons but it’s also common to use opening detectors as an alarm for the care of the elderly, especially those with memory impairments, in social institutions or at home if they live independently despite their age and signs of the disorder, or to monitor children.

Compatibile with all Ajax hubs and Ajax Range Extenders. The detector is not compatible with ocBridge Plus and uartBridge integration modules.

Please note: DoorProtect Plus operates within the Ajax system, connected to the hub via the protected Jeweller protocol.
