Description

The System Sensor MDL Module comes designed to work with the SpectrAlert 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.

In general, each System Sensor MDL SyncCircuit module has the capability of connecting two Style Y circuits or one Style Z circuit. Also, the zone output(s) from the panel are connect to the zone input(s) of the MDL module and the zone output(s) from the MDL module are connect to the notification loop(s). Besides, supervision is accomplish in the module by a direct connection between the zone input and the zone output of each of the two-zone circuits connect to the normal end-of-line device. The FACP “sees” the EOL device through the MDL module. When either or both outputs from the module are wire to the SpectrAlert products; the horns or chimes and strobes in both zones will be synchronize.
