Which safety equipment helps identify heat changes in a building?

Thermostatic detectors are specifically designed to monitor temperature changes within a building, making them essential for fire safety. These devices can detect variations in heat and are often used to trigger alarms or activate fire suppression systems when a predetermined temperature threshold is exceeded. By continuously measuring the temperature, thermostatic detectors provide early warning signs of potential fire hazards, allowing occupants to evacuate safely and enabling fire response teams to act quickly.

In contrast, smoke alarms primarily detect the presence of smoke rather than measuring heat changes directly. Pressure gauges are used to monitor fluid or gas pressure levels and do not relate to temperature monitoring. Carbon monoxide detectors focus on detecting the presence of carbon monoxide gas, which is a different aspect of safety that relates to toxic gas levels rather than heat changes. Each of these other options serves important functions but lacks the specific capability to identify heat changes like thermostatic detectors do.
