What is the maximum number of supervisory signal-initiating devices that can be connected to a single initiating device circuit?

• A. 10
• B. 15
• C. 20
• D. 25

Answer: (C)

The maximum number of supervisory signal-initiating devices that can be connected to a single initiating device circuit is 20. This limit is often set by the manufacturer’s specifications and regulatory codes to ensure system reliability and functionality. Connecting too many devices to a single circuit can lead to issues such as inadequate voltage, poor signal integrity, and decreased responsiveness. Additionally, having a specified limit helps facilitate troubleshooting and maintenance by ensuring that systems remain manageable. This balance allows for optimum performance and safety in alarm systems, where initiating devices play a crucial role in detecting unauthorized access or environmental changes. Understanding this limit is critical for complying with installation codes and ensuring that the fire alarm or security system operates effectively within designed parameters.
