The Tamper Resistant Sensor Pad Alarm Systems are a great option for alerting caregivers to potential falls. The sensor in the pad triggers an audible alarm when a patient attempts to rise. The moment the patient's weight has been removed from the pad, the caregiver is instantly alerted by the sounding alarm. Why use this product? • Thin pad which is non-restrictive, less detectable by patient • Lower risk of patient tampering with alarm settings. • Easy to use, simple setup • Urine-resistant • Bed pad measures: 11 x 30 in (28 x 76 cm) / Cord length 68 in (173 cm) How it works: • Alarm is triggered when patient's body weight is lifted off pad • Alarm resets when pressure is reapplied to sensor pad The alarm unit which comes with this system (see 16M120A) is tamper-resistant, perfect for patients who continually turn off alarms, disconnect sensor pads, or break alarms. It's always on – patients can't turn it off and caregivers won't forget to turn it on. All alarm settings are concealed under the battery cover.
