For alarming systems, what is the maximum number of heat alarms in residential setups?

In residential alarming systems, particularly those involving heat alarms, the maximum number of heat alarms that can be interconnected is typically limited by safety standards and regulatory guidelines. The correct option indicates that 18 is the maximum number of heat alarms allowed in a single residential setup.

This limitation is crucial for several reasons: it helps ensure that the system remains manageable and can be effectively monitored without overwhelming the user with excessive alarms. With a limitation of 18, users can maintain a balance between comprehensive coverage of their property and a streamlined, effective alarm response. Exceeding this number could lead to alarm fatigue, where individuals become desensitized to alarms and might not respond promptly in genuine emergencies.

In the context of building and fire codes, these regulations are designed to enhance safety in residential environments, ensuring that an adequate number of alarms can communicate effectively without compromising the system's reliability. Other numbers presented in the options exceed this recommended limit, potentially leading to safety risks or complications in alarm management and response efficiency.
