## Overview

The Nesthao Upgraded Bed Sensor Alarm is a wireless motion detection system designed to monitor elderly or dementia patients’ movements with a 918ft transmission range. Featuring 5 volume levels, dual power options (battery and USB-C), and a discreet alarm that only sounds on the caregiver’s receiver, it prevents falls by alerting caregivers the moment a patient’s foot touches the floor. Easy to install under beds or at doors, it minimizes false alarms and maximizes peace of mind.

## Description

Senior Care Alarms: Wireless bed alarms for seniors alert you when the patient gets out of bed and will assist you to prevent falls when you lift patient motion sensor: The wireless caregiver alarm allows caregivers to monitor their movements freely and remotely. The receiver offers two power supply modes: battery and USB C. No need to connect the bed alarm receiver to the power supply all the time. You can control the movement of the elderly for the first time.

## Features

- Easy to monitor loved ones getting out of bed or leaving the room, wireless motion sensors can be placed on the floor under the bed to trigger an alarm when the patient's foot is about to touch the floor, or they can be placed on the door to monitor loved ones leaving the room, transmit the signal to receivers within 918 feet in open area.
- The bed alarm does not sound in the patient's room, potentially startling them and causing a fall. The motion sensor would start the self-test procedure first when turned on (the indicator light would flash slowly for 20 seconds), after the light turned off, the machine would enter working state. Please test the detection range and direction before fixing it.
- Unlike traditional bed sensor pads, the motion sensor can simply be placed on the floor under the bed to accurately detect when a patient's foot touches the floor when getting up, without worrying about false alarms due to incontinence and patient displacement.
- Dual reminder (LED light/sound) and dual power supply (alkaline battery/micro USB)
- 1 x Caregiver Locator (include 3*AA batteries) 1 x Motion Sensor (include 3*AAA batteries) 1 x Micro USB 1 x Double-sided adhesive tape 1 x Screw kit and manual

A: The bed alarm infrared can sense the movement of 6ft-26ft (with temperature changes), and can transmit the signal to the receiver of 918ft (open ground)

**Q: I want to have a second receiver. can i have two receivers. so i can hear one in my room and one in den.**
A: We don't sell receivers separately, but you can order two sets at the same time, learn from each other and pair them according to the instructions to work together

**Q: If you cover up the indicator light will it affect the ability to sense motion?**
A: No. It will not affect the sensor.  The rectangular screen below the indicator light is the motion sensor, which you don’t want to cover up.

**Q: Pairing with multiple sensors.
Do I have to turn the power off to sensor #1 before pairing sensor #2 or do I leave them both on?**
A: When the receiver is off, press and hold the volume button for 3 seconds. After hearing the 'Di' sound, switch on the infrared sensor to be paired. Wait for 20 seconds and wave in front of the sensor
