In 1970, Space Age Electronics introduced the first visual notification appliance, the AV32 light plate (which was installed over an existing horn) and V33 remote light. Meanwhile, in 1976, Wheelock introduced the first horn/strobe notification appliances with its 7000 series. The majority of visual signals throughout the 1970s and 1980s were ...

The SpectrAlert series included horn strobes, strobes, remote horns, chimes, chime strobes, speakers, and speaker strobes. A main feature of these alarms was the ability to sync them using a System Sensor MDL sync module or the System Sensor sync protocol on a supported fire alarm control panel .
