Intended for use on the floor or on a bed, this is the Large sized version of the Premium Sensor Mat, which is designed to be used in conjunction with the Anti-Tamper Care Alarm or Voice Alert Monitor.It will activate an alert sound if it senses a sudden increase or drop in pressure over its surface - for example, if someone steps on it when approaching a door or staircase, or if the user falls out of bed. Easy to clean, and comfortable to use, the Premium Sensor Mat provides the carer with an immediate warning that the user may require assistance.
