Control Relays with BIOU Interface

Up to two BIOU interfaces can be installed to provide control relays for Night Bell, Night Transfer, Door Lock and BGM mute control. Each BIOU provides four control relays for a total of eight relays (max.) per system. Each relay’s function is selected in system programming. BIOU interfaces can be installed in the main cabinets and/or any remote cabinet (see Figure 12-8).

BIOU control relay contact power ratings are shown below:

24 VDC maximum

1.0 amperes maximum

CAUTION! BIOU relay contacts are not rated to switch 120/240VAC, connecting these voltages may result in equipment damage, fire and/or personal injury.
