Attendant Control OpenBus (ACO) is a flexible control unit with numerous optional functions. Can also be used as handset keys and/or lock out controls. Compatible with OpenBus control boxes.


The Attendant Control OpenBus™ (ACO) is a cost optimised and compact unit with up to 21 buttons that can be used as hand control keys or lock-outs. The lock-out function can be made visible by using yellow LEDs.

The ACO is compatible with control boxes that use an OpenBus interface. The ACO is for use with advanced hospital and patient care beds (nursing beds) where patient positioning must be carefully controlled by medical staff.

The ACO allows nursing staff to retain direct control over critical positioning functions while giving the patient a limited degree of adjustment. This high degree of selective control is vital in cases such as spinal injuries and other similar conditions where backrest positioning must be carefully supervised.

The ACO is ergonomically designed and easy to install on even the most advanced equipment. The ACO has a flexible "hook" which enables it to be positioned according to the nurses wishes, out of reach of the patient (for example at the end of the bed), and serves to block the hand control functions that may be inappropriate, or even dangerous to the patient, (for example in connection with a broken leg).
