Wireless calling system

Wireless calling system is widely used in service area. This calling system consists of call bell, main monitor, pager and repeater. When the guest needs any service, he or she press the button on the call bell, its number will show on the pager and main monitor with sound. So the staffs can offer service very timely.



Restaurant calling system

For restaurant use, this wireless restaurant calling system is typically placed on or attached to each table. When a guest wants the server, he/she presses the button of a call bell, which sends a signal to the main monitor. The main monitor shows numbers, usually table numbers, which the guest has sent, and flashes briefly and beep sounds to indicate that a new call has been received.



Hospital paging system

A nurse call button in the wireless call bell system is found around a hospital bed that allows patients in health care settings to alert a nurse or other health care staff member remotely of their need for help. When the button is pressed, a signal alerts staff at the nurse's station, and usually, a nurse or nurse assistant responds to such a call. With our wireless calling system, patients can simply beep or buzz at the station, requiring a staffer to actually visit the patient's room to determine their needs.
