A panic alarm is a security device that is used to send an alert signal to hotel employees or related departments in case of an emergency so that they can take timely action. These emergency alarms are usually installed in public **** areas, guest rooms and other key locations of a hotel to ensure that the hotel can respond quickly and provide assistance in the event of a fire, burglary, medical emergency and more. The type and function of emergency alarms may vary depending on the size and standard of the hotel, but they typically include fire alarms, emergency call buttons, security access control systems, and more. The purpose of these devices is to ensure the security of the hotel and the safety of its guests, and to provide prompt support and assistance in case of an emergency.
