The Roam Alert System provides effective wander prevention that is easy to implement, and easy for your staff to use. And it's proven itself at thousands of facilities over a period spanning more than 20 years. The RoamAlert Door Controller monitors an exit in a facility using the RoamAlert wander prevention system. The system provides freedom of mobility to residents in senior care facilities, while ensuring that they remain safe. The Controller generates an exciter field which defines the door coverage area for resident and other tags. When a tag enters the Controller’s exciter field while the door is open a Wander alarm is generated. If the door is closed, the Controller can activate a maglock to hold the door securely shut, and can generate a Loiter Alarm at the computer if the resident does not move away from the door within 55 seconds.
