Conventional Fire Detection Systems is a traditional fire control panel with integrated operating unit for 2-12 zones. The controller is designed to be very simple to use while offering exceptional flexibility with a comprehensive list of features. Notice comes from the group of sensing elements called zones. This system is ideal for small applications. Extensions and accessories must be ordered separately. Special Gas Extinguishing panels are also included in this group. As a basic structure, there are two detection zones in a quench zone. When a fire alarm is received from both zones, a simple circuit extinguishes the output. The solenoid valve is activated and extinguishing occurs.
