IQ Duo Plus Alarm is truly versatile. It is the answer for facilities consistently switching between pull-cord alarms and sensor alarms. This alarm has both options, pull-cord or sensor alarm. Sensor Pad Alarm Systems are a great option for alerting caregivers to potential falls. The sensor triggers an audible alarm when a patient attempts to rise off the pad. The moment the patient's weight has been removed, the caregiver is instantly alerted by the sounding alarm.
