Yes, "office facilities" usually refers to toilets, kitchen areas, etc. "Facilities" is also used as a general term to cover such things as provision of electrical power, lighting, fire equipment, etc.
I wouldn't say "office devices". For printers, scanners, etc. I would say "IT equipment" or "peripheral devices" or "peripherals". For binders, shredders, laminators, etc. I would say "office equipment".
