An audible and visual alarm is triggered when smoke or fire is detected, and hotel staff and local fire departments are notified accordingly.
  • Intrusion Alarm System: The intrusion alarm system is used to detect unauthorized individuals entering restricted areas of the hotel, including employee passages, storage rooms, and guest rooms. Typically, this system is integrated with sensors, access control systems, and cameras to monitor the hotel’s security in real time.
  • Emergency Communication System: The emergency communication system is used to convey important information to employees and guests during emergency situations. It can be used to broadcast emergency notifications, provide evacuation instructions, or communicate with security personnel.
  • Video Surveillance System: Cameras installed in key areas record and monitor various activities in the hotel. Usually, these cameras are connected to a security center to assist in monitoring and reviewing events.
  • Emergency Call Buttons: Emergency call buttons are installed in public areas, guest rooms, and employee passages, allowing guests and staff to seek assistance in emergencies.
  • Elevator Malfunction Alarms: Hotel elevators are typically equipped with emergency alarm buttons to respond to situations where passengers are trapped or elevator malfunctions.

Through the synergy of these alarm systems, hotels can better respond to potential threats and keep hotel guests and employees safe.

5. Fire Detection and Suppression Systems
