Wireless Wander Door Alarm Alzheimer's wandering can be inconvenient at best and dangerous at worst. The Wireless Wander Door Alarm alerts staff when a resident attempts to leave his/her room or inadvertently wanders into an unattended area. This two-part alarm system has a door sensor mounted in the resident's room and a wireless receiver/alarm carried by the caregiver. Door sensor attaches easily to both sides of the doorjamb. When the door is opened, an electronic signal is sent to the remote receiver, sounding an audible alarm, and alerting the caregiver that the resident is either wandering out of safe range or entering a nonsupervised area. Excellent for home use too by offering caregivers the peace of mind and freedom to attend to other duties. System includes mounting materials and one battery for the door switch. A 9-V battery is required (not included) for the chime/vibration.
