When designing an alarm system, what is a critical factor in selecting alarm cable?

Selecting the right rating of the alarm cable is crucial when designing an alarm system because the rating indicates the cable's ability to handle specific electrical loads and environmental conditions. The cable rating ensures the system operates reliably under certain voltage levels and in various temperature ranges. Using a cable with an inadequate rating could lead to overheating, signal loss, or malfunctioning of the alarm system, potentially compromising security.

In addition, the rating often includes certification standards that ensure the cable can withstand interference, which is vital in an environment where electronic devices may cause disruptions. This factor is essential for maintaining a consistent and reliable connection between the alarm components, allowing for effective monitoring and response to security breaches.
