Alarm Sensor

Security systems are an extremely important component of protecting any building and its contents, whether it be residential, retail, or other. In order to adequately notify an owner of a break-in, the semiconductor devices integrated into the alarm circuit must demonstrate rapid response times and be highly reliable. AEM has a wide portfolio of discrete devices that are both fast-switching and of the highest quality, guaranteeing optimal security system operation.
