Comprehensive Detailed Explanation:
Nuisance alarm rate is a measure of system reliability and is calculated by tracking the number of false or unwanted alarms over a specified time. This metric is crucial for tuning sensor performance and reducing unnecessary responses.
A, B, and C provide insights but are not standard methods of calculating nuisance alarm rate.

Record safes are designed primarily to protect documents from fire, not theft. They often lack adequate burglary resistance features. Using record safes for storing valuables such as cash, jewelry, or sensitive items prone to theft is a major security vulnerability. This misapplication can lead to easy compromise during unauthorized access or burglary.

An Uninterruptible Power Supply (UPS) is the best solution to immediately mitigate the risk of power loss in a computer. It provides backup power instantly upon power failure, allowing safe shutdown or continued operation for a limited period.
A (Surge protector) protects against voltage spikes but doesn't provide backup power.
C (Emergency generator) has a startup delay and is more suitable for large systems.
D (Batteries) are components of a UPS, not a standalone mitigation.

The pre-bid conference is held to clarify specifications, answer bidder questions, and ensure all prospective contractors understand the requirements. It supports transparency and consistency across all bids.
A is incorrect-bids are not anonymous.
C misrepresents the purpose of the meeting.
D (Disclosing project cost) may or may not occur, and it's not the primary goal.

Comprehensive Detailed Explanation:
Site Acceptance Testing (SAT) verifies that a system has been installed properly and functions as intended in the actual operating environment. It checks for compliance with design specifications, performance standards, and functional reliability under real-world conditions.
A (Factory Acceptance Testing) occurs before delivery at the manufacturer's site.
B (Reliability testing) focuses on system stability over time.
C (Equipment performance testing) is narrower and usually component-level.
