Answer / Shorabh Kumar Barnwal

Fire control panels use various cards to control and monitor fire alarm systems. Some common types include: 1. Addressable Initiating Device (I/O) cards: They communicate with smoke detectors, heat sensors, and manual call points. 2. Control Relay (CR) cards: These manage outputs, such as activating warning signals or controlling fire suppression equipment. 3. Power Supply (PS) cards: They provide power to the system components. 4. Communication (COM) cards: They facilitate communication between different fire control panels and with monitoring stations.
