Abstract (en)

[origin: EP3435348A1] An object of the present invention is to send out an early warning of the presence of carbon monoxide to a location other than the origin of the carbon monoxide. A security system (100) includes a plurality of fire alarms (1) and a sensor (2). Each of the fire alarms (1) includes a fire detector (11), a first communications unit (12), and a first control unit (13). The sensor (2) includes a CO detector (21), a second communications unit (22), and a second control unit (23). Upon detection of carbon monoxide by the CO detector (21), the second control unit (23) makes the second communications unit (22) transmit a notification signal to the fire alarms (1). Upon receipt of the notification signal at the first communications unit (12), the first control unit (13) sends out a CO coordination alarm, and also makes the first communications unit (12) transmit the notification signal to the other fire alarms (1).
