The Secure MAT-3 Floor Mat Sensor Bed Alarm Set is designed to help prevent elderly patients or residents from falling and wandering. This bed alarm for seniors includes a 24" x 36" professional-grade floor mat sensor that can be placed next to a bed, in front of a chair/wheelchair, or a doorway. When a patient or resident steps on the mat, the caregiver is alerted by the included SMA-120 Patient Alarm Monitor. The set also includes a PH-1B Alarm Monitor Holder, 3x AAA batteries, and an ACDC-1 Power Adapter for immediate use. The SMA-120 Alarm Monitor features adjustable volume settings of 80, 90, or 120 dB, an adjustable alarm tone, and is nurse call interface compatible (with an optional NCI-1 cable). Other features of the SMA-120 Alarm Monitor include an in-room sound on/off switch (in-room alarm sound can only be silenced when connected to a facility nurse call system), an optional AC power supply to save battery life, a wall mount option, a tamper-resistant cover, 8 ft. connecting cord, and low battery indicator sound & light. The flashing alert light bar allows caregivers to easily identify the activated alarm monitor. All bed alarm components are covered by a one-year warranty and a hassle-free replacement guarantee.
