What characterizes a fail-secure lock?

1. It remains locked when power is lost

2. It unlocks during a power failure

3. It requires continuous power to secure

4. It can operate wirelessly

The correct answer is: It remains locked when power is lost

A fail-secure lock is designed to enhance security by remaining locked even when there is a power failure. This characteristic is particularly important in high-security environments such as healthcare facilities, where unauthorized access during an emergency could pose significant risks. The fail-secure design ensures that doors remain locked, preventing access to sensitive areas when the power goes out, thereby maintaining safety and security. In contrast, options that suggest the lock would unlock during a power failure or require continuous power to secure do not align with the definition and purpose of a fail-secure lock. Furthermore, while locks that can operate wirelessly may have advanced features, the primary characteristic of a fail-secure lock specifically relates to its performance during a loss of power, further emphasizing the importance of security in critical environments.
