It is worth checking with the nurse call manufacturer as some do a switch interface box. Static Systems do the pn75792 unit which takes either a 3 or 6mm jack input, I am not sure about other companies.

Hi Will,
Short or long version...?!?
The simplest way is to pull apart the original pendant and see how it works. Sometimes you can just provide an alternative switch wired to emulate the original circuit. For systems with integrated speakers for TV or lamp controls, we usually fit a socket so an external call switch works in parallel with the built in button. The same applies to systems that send serial data and not just a simple circuit closure.
For some patients we set up sensitive switches, and then add an intention delay timer to reduce false alarms and give the user confidence.
The other issue is switch choice, positioning and staff training.
Cheers,
James Dean

Hi All
Has anyone had any experience in wiring up a switch to a regular hospital bedside call system? The patient's call bell socket is a standard telecom socket.. Does this ring a bell (get it?!) with anyone?
Many thanks
Will
