A building security system includes an emergency communications system of an elevator installation, and a building alarm system. The emergency communications system has a communications interface to couple the emergency communications system to a remote elevator service central in an emergency situation, and an emergency call panel arranged in an elevator car to allow a passenger to communicate with the remote elevator service central via the communications interface while in the elevator car during the emergency situation. The building alarm system includes a plurality of sensor units arranged at predetermined locations of the building and selected to detect predetermined building events. The building alarm system is communicatively coupled to the emergency communications system of the elevator installation for communicating the building event to the elevator service central via the emergency communications system of the elevator installation, and/or for receiving an action request from the remote elevator service central via the communications interface of the emergency communications system.
