Garage Master, a three-in-one automated system that functions as a garage door closer, receiver and a carton monoxide door opener, has been launched in recent days. It includes a carton monoxide door opener that opens the garage door after sensing the CO detector's alarm.The 'Garage Master' also functions as a Garage Door Closer allowing homeowners to set their garage door to close after predetermined period of time. A garage door monitor will sense if the door is fully closed. If the door is ajar, a wireless signal is sent to the Garage Master. Then the homeowner can activate the garage door to close through the Garage Master.
