The TL-2100S Monitor is designed for use with all Smart Caregiver corded sensor pads and mats. Simply plug a sensor pad into the monitor and place the pad under the resident in a chair or bed. When the resident gets up and pressure is removed, the alarm will sound notifying caregivers that the resident is on the move. This alarm features a Safety Auto-Reset™ Function which will automatically reset and silence the alarm when pressure is re-applied to the sensor pad. When set to TamperProof™, the Monitor alert can ONLY be reset using the provided Caregiver Key™. Selecting this setting ensures that only the designated caregiver can silence the alarm. The TL-2100S has been designed without an ON/OFF switch to sure that the monitor cannot be accidentally disarmed. And since the monitor automatically turns back on when pressure is re-applied to the connected sensor pad, the system is always on and ready for immediate use.
