When must an alarm system be functioning and armed?

An alarm system must be functioning and armed every night to ensure the security of the restaurant during non-operating hours. This practice helps protect the premises from theft, vandalism, or any unauthorized access when the staff is not present. By arming the alarm system every night, management is taking proactive measures to safeguard their inventory, equipment, and overall property.

Having the alarm system operational during the night is part of a comprehensive security protocol that helps minimize risks and ensures compliance with safety regulations. This requirement reflects the importance of maintaining a secure environment, particularly in a business like Chipotle, where fresh ingredients and valuable equipment could be at risk.

While the other options suggest various frequencies or conditions for arming the system, they do not provide the level of security needed to protect the establishment outside of operating hours. By ensuring that the alarm is armed every night, the restaurant minimizes potential threats and enhances overall safety.
