Wireless Smoke and Heat detectors have a built-in radio frequency module which allows them to communicate with their paired control panel and other wireless devices on the system. They are the primary means of fire detection, constantly checking for the presence of key fire indicators and reporting back to the panel when a potential fire is noticed. Wireless Detectors are also addressed and can be assigned to virtual zones, similar to Addressable Fire Alarm Systems, to aid occupants and emergency services in locating the fire by displaying relevant information on the Wireless Control Panel.
