The Wireless Fall Monitor is connected to a corded weight-sensing floor mat and is ideally placed by the bedside or in a doorway. When the resident gets out of bed or tries to leave the room and weight is applied to the floor mat, it will then send a signal to a monitor and then on to the pager to alert the caregiver. The Wireless Fall Monitor and Wireless Pager system is designed to send and receive alerts remotely via wireless signal to notify the caregiver. Battery Operated (3-AA, Not Included). Optional AC Power Adapter (AC-05).
