It is very important to get the necessary help in emergency situations on time. The wireless calling system aims to alert service personnel in a timely manner in the event of an emergency call. Call modules are usually installed next to the bed in the toilet or bathroom. The button, which is installed in the bathroom, is waterproof and has a cord with a cord with Philips for greater convenience. Both modules have a button to reset the call. All signals are visualized on an LED display with the number of the room or bed from where the call came. In a system, depending on the need and specific requirements, an unlimited number of displays and handheld receivers can be used, which facilitate the staff and guarantee a timely response to each call.
