• Standard front cover has improved user layout. 

The self-explanatory buttons and their 

functions are easy to locate and operate 

• High strength plastic housing protects the 

electronics 

• Cleaning is made fast and easy because of 

rounded contours and assembly of the cover 

onto a low edged surface 

• Protection against single fault condition 

according to EN 60601-1 when connected with 

control boxes that use an OpenBus interface 

e.g. CB20. 

• A LED indicates when the battery is being 

charged (yellow) 

• Protection class: IPX6 or IPX6W 

• Colour: Grey RAL 7035 

• Connection to CB or MJB via a “modular jack” 

cable 

• Flexible “hook” (dimensioned to fit onto either 

a Ø32 mm or 42 mm rail) 

• The front cover seals the ACO housing 

Options: 

• Customised front cover 

It is possible to design front covers where the 

keys and LED´s are placed differently than on 

the standard LINAK front covers. This involves 

some development and tooling changes / costs. 

Usage: 

• Compatible with OpenBus e.g. CB20, CB6S 

and CB16 

• Ambient temperature +5˚ to + 40˚C 

• ACO IPX6-Washable is approved according to 

EN60601-2-52. 

In order to comply with the norm the ACO must 

hang vertically from it’s hook during the 

washing process, see the picture next page 

Current consumption: 

• 15 mA (Standard versions with 5 no. LED’s 

(5 LED’s x 2 mA = 10 mA) + microprocessor 

5 mA, total = 15 mA 

The ACO (Attendant Control OpenBus) is a cost 

optimised and compact unit with up to 15 buttons that 

can be used as Handset keys or Lock-outs. 

The lock-out function can be made visable by using 

yellow LED´s. 

The ACO is compatible with control boxes that use an 

OpenBus interface i.e. CB6S, CB16 and CB20. 

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 handset functions that may be 

inappropriate, or even dangerous to the patient, (for 

example in connection with a broken leg).

Recommendations: 

• Always use Locking ring and cables with O-rings. 

• Locking ring and cables with O-rings must be fitted to ensure IP degree. 

• If other front covers than standards are requested, the customer must design them. 

• Cables are inclusive an O-ring.
