Zen Node is a small attractive wireless appliance that “listens” to the unique sound of a smoke detector alarm and notifies you by text message or email. Zen Node also has a built in “Help” button which once pressed, generates email and text message which allows anyone in need to summon your help immediately. The communication between you and your Zen Node is direct and frees you from dependency on any external monitoring company. As a result there is no need for monthly fees, service plans or contracts; making it the lowest cost monitoring and alert device on the market.
