The IC/SM alarm panel is designed for continuous operation and normally will not be shut down except for ______.

The IC/SM alarm panel is designed for continuous operation to ensure constant monitoring and response capabilities. Maintenance is a necessary activity to ensure that the system remains functional and reliable over time. This includes regular checks, updates, and repairs that might be required to keep the system performing optimally.

Shutting down the panel for maintenance allows technicians to inspect, clean, or replace components that may have worn out or malfunctioned. This proactive approach helps prevent potential failures that could compromise the alarm system's effectiveness. Other choices, while important in their own contexts, do not typically require a complete shutdown of the system. Upgrades and system audits can often be performed while the system is operational, and emergency cases would ideally involve keeping the system running to address the emergency effectively.
