Which of the following types of signaling systems refers to alarms that are monitored on-site?

The type of signaling system that refers to alarms monitored on-site is the local signaling system. In this setup, alarms are triggered and can be seen or heard directly at the location where they occur, allowing for immediate action to be taken by on-site personnel. This could involve alerts such as bells or lights that help ensure that individuals present at the site are aware of an emergency and can respond accordingly.

Local signaling systems are typically used in smaller facilities or areas where a quick response is vital, and immediate notification of personnel is necessary to address any issues. This contrasts with other systems designed for off-site monitoring or centralized responses, thereby highlighting the unique focus of local systems on direct, immediate awareness and action in the environment where the alarm is activated.
