 We have had a very encouraging response to the NC12/SOCO, our latest development project, in terms of sales and feedback. The main point of note has been the simplicity of operation as it has only one function, that is to put a call on the nursecall system when the service-user has moved from the chair or bed or is in the process of doing so. Then, when not in use simply unplug. Another very popular benefit is the ease of up-keep, because with no batteries involved its one less job to do. Also, in response to your valuable feedback, the latest design has the power cable directly wired into it, which means the power supply can’t get lost, therefore giving greater peace of mind. Behind the scenes we have been impressed by the flexibility the NC12/SOCO offers, maybe this is because of the intrinsic simplicity of the design. Though developed to answer the need for a simple, “no-fuss”, chair and bed leaving application another very effective use of the NC12/SOCO is a floor sensor pad being used on a normally closed system such as encountered with SAS II, Eclipse and old Haes’ ‘Nightingale’ systems (here the sensor pad has to ‘appear’ as a closed switch until stood-on, which then opens the circuit and initiates a call). For information purposes (for those are interested) I would explain that all sensor pads, no matter their internal make-up, present as an open switch and applying pressure to them closes the switch. Most mainstream nursecall systems, such as Quantec, Nursecall 800, and Intercall have input sockets, on the bed-head ‘call points’, to plug in remote devices such as buzzers and sensor pads. These remote devices especially sensor pads all use an open circuit switch and are configured so that when pressed, and the switch is now closed, a call is initiated onto the nursecall system. On these systems when we have a chair or bed sensor pad that is being used as a closed-circuit switch, where a client’s body weight is closing the switch, we need a device to invert that signal to an open switch at the ‘call point’. The NC12/SOCO does this, so that when the service user stands or sits-up the pressure is released and a call results that will continue until they sit or lay back down and the ‘call point’ is reset. When not in use simply unplug.
