How are heat detectors connected to each other in a system?

Heat detectors in a system are typically connected in parallel. This connection allows each detector to operate independently of the others. If one detector triggers an alarm due to excessive heat, it does not affect the functionality of other detectors in the system. This setup is crucial for ensuring that the entire system remains operational even if one unit fails or is activated, thereby enhancing overall safety and reliability.

Connecting heat detectors in parallel also simplifies the wiring and reduces voltage drop across the circuit, making it easier to maintain consistent performance across all detectors. Additionally, it facilitates easier troubleshooting, as individual detectors can be assessed without disrupting the entire system.
