Nurse Call Systems

I need a special report on sköterskelarmet system systems. I knew what is the species (such as wireless and12AC/dc etc.), but I could not know how to dose the system works because it is the type of signal used figuur?, There passed a microprocessor unit involved the basic units Nurse in the system?, What is the type of signal that it is? Thanks to the old wired system uses the direct connection of the room / bed to the panel discussion. Newer wired systems will be connected by bus, with each tick has a unique serial code for over a bus network. I doubt there will be wireless, but the rooms ring panel on a bus system, when connected to a wireless pager that systemso staff will receive a call. In our hospital we have a new system that can locate which room you are in. It can also specify which part of the device you in the hallway outside a room number, ie. We bring these markers on the uniforms and equipment when the Secretary receives a call to reception, which pages on our sirens are all connected to the nurse call system very well .
