Wireless Calling System Buzzer - 20 Par Receiver + 1 Keypad Transmitter, Guest Paging Cafe Coaster, Precise Control

Compact guest paging solution for restaurants and service queues. Power on/off is simple: placing 20 pars on the charging slot turns them on, and pressing 999+CALL will turn off the 20 pars on the charging slot. Operation is straightforward and fast, saving staff time. Expandable capacity and charging: the system supports expansion up to 998 pars to handle large queues. A single keypad can charge up to 20 pars at the same time. Long battery life and efficiency: each par includes a built-in 3.7V 230mAh rechargeable lithium battery. After a full charge, a par can run for about 200 hours thanks to low power consumption technology. Multi-keypad compatibility: the system allows multiple keypads with the same ID to call the same par, addressing the problem of multiple keyboards attempting to call the same device. Ideal for high-turnover and queued environments such as fast food restaurants, food courts, clinics, churches, auto shops, and other situations where orderly guest paging is needed.
