AI-500 Addressable Input Module is designed to receive normally open or normally closed switch signal from fire devices with coincidence functions, and transmits these messages to fire alarm control panel (FACP) with coincidence detection function. When a device of this kind is activated, the module can send the output signal through signal loop to FACP to alarm or activate relative devices.
