What is the maximum length of a fire alarm circuit between devices without needing a repeater?

The maximum length of a fire alarm circuit between devices without needing a repeater is 2000 feet. This standard is established in various fire alarm system codes and guidelines. The distance limitation is important because it ensures that signals transmitted between devices are strong enough to maintain reliable communication and system integrity.

Longer distances can lead to issues such as signal degradation and delays, which are critical in fire alarm systems where timely alerts are essential for safety. While the specific regulations can vary by locality and the type of system employed, a limit of 2000 feet is a common threshold that balances these concerns effectively. Therefore, following this standard allows technicians to effectively plan the layout of fire alarm circuits while adhering to safety protocols and ensuring optimal functionality.
