The transmitter and receiver of this home alarm system achieve an operating range of 230 feet/70 metres in open areas. Compared to standard devices, it offers superior interference resistance, enhanced penetration capability and stable signal transmission, capable of traversing multiple walls. However, thick walls or metal walls may reduce reception distance. Please test the actual range upon receiving the product. The emergency call button alarm serves as a thoughtful gift for the elderly, patients, and those with limited mobility. Featuring 12 selectable melodies, it can also be shared with family and friends.
