K10SCO is a dual smoke and carbon monoxide sensor equipped with a voice alarm and two independent sensors. Optical is responsible for detecting fire alarms, while electrochemical for detection of carbon monoxide (CO). In the case of detection of a fire or/or exceeding the permissible carbon monoxide concentration, an 85DB acoustic alarm is started, an optical alarm (red LED) and voice notification is emitted (in English) informing about the type of threat detected. The Test/Reset button allows you to control and support the sensor. The device's memory is saved information about detecting a dangerous concentration of CO or a fire hazard. Thanks to this, the user can check whether carbon monoxide emissions have not been broadcast during the absence of a room, for example. The sensor can be mounted on both the ceiling and the wall. It is powered with 2 x 1.5V AA alkaline batteries. This solution allows you to install the sensor in an optimal place in the room and also provides protection in the event of a power supply disappearance on the network. The built -in automatic efficiency control system is constantly monitored, among others The condition of the sensors and internal circuits. If the fault is detected, the signaling appropriate for damage is turned on.
