Product Details
The MDL3 Synch Circuit Module is designed to work with the SpectrAlert Advance series of notification appliances to provide a means of synchronizing the temporal coded horns and chimes, synchronizing the one-second flash timing of the strobe, and silencing the horns and chimes of the horn/strobe and chime/ strobes combination over a two-wire circuit while leaving the strobes active.
Each MDL3 module has the capability of connecting two Style Y (Class B) circuits or one Style Z (Class A) circuit.
