A heat detector responds to changes in temperature, typically activating an alarm when a certain temperature is reached or when there is a rapid increase in temperature. A smoke detector, on the other hand, detects smoke particles and activates when smoke is present, even at lower temperatures. Both serve different purposes and can be used together for better fire protection.

Heat alarms are ideal for locations where cooking or other activities may produce smoke that could trigger false alarms, such as kitchens, attics, and garages. They are also beneficial in areas with high humidity or dust, where smoke detectors might be less reliable.

Heat detectors should be installed in areas where smoke detectors may be less effective, such as kitchens, attics, and garages. They should be placed on the ceiling or high on the wall, at least 4 inches away from walls and other obstructions. Always follow the manufacturer's guidelines for specific installation locations.

To maintain your heat detector, regularly check it at least once a month to ensure it is functioning properly. Clean the device with a soft brush or vacuum to remove dust and debris. Additionally, replace the batteries annually and replace the unit every 10 years to ensure optimal performance.
