In cold weather, a fire alarm sprinkler water storage container must be monitored to indicate when the water temperature drops below what level?

Explanation:
In cold weather, sprinkler water must be kept from freezing, and early warning helps you take action before that happens. The monitor is set to trigger when the water temperature falls below forty degrees Fahrenheit. This margin above freezing gives you time to activate heat, circulation, or insulation to protect the water supply and keep the system ready. Waiting until it drops to freezing (32°F) would be too late and could allow ice to form in the storage. Values like 45°F or 50°F would imply alarms earlier than typical practice, so forty degrees is the standard threshold.
