ACU3 Antenna Changeover Unit
Part Number: 101192
ACU3 is a main/standby antenna relay. If an error occurs in the main unit, the ACU3 switches the antenna from the main unit to the standby unit. It can be fastened to a DIN rail with clips or mounted to the wall of a subrack.
Operating modes
The unit can operate in different modes. Mode selection is done by using the DIP switch located on the board inside the unit. There are two distinct modes of operation:
- Key controlled mode – the ACU will select the transmitter that is keyed and stay there until the other transmitter is keyed.
- Alarm controlled mode – the ACU3 relay is controlled by the alarm state of the transmitters.
Each mode has different options that can be enabled or disabled.
