Leakage Current Impact
All light modules, sound modules, and light/sound modules are capable of absorbing up to 3 mA of leakage current from solid-state outputs without module activation. Some light and light modules with sound may not turn off completely when connected to solid-state outputs which emit leakage current. Listed below are modules that were affected by an output module emitting a maximum of 3 mA. A dry contact can be used to eliminate the effect of leakage current.
12V AC/DC, 24V AC/DC, 120V AC, 240V AC		All light/sound combination modules
