Full-wave rectification rectifies the negative component of the input voltage to a positive voltage, then converts it into FWR (pulse current) utilizing a diode bridge configuration. Many Panels only do this. It causes problems with The Strobes of Notably Simplex and Faraday Notification appliances. Mechanical horns, TrueAlerts and System Sensor SpectrAlert Classics will sound very raspy/scratchy and it can eventually kill them.
