Metal detectors actually detect anything that can conduct electricity. To make metal from rocks you would have to smelt them, and this requires both a lot of heat, and something like carbon to reduce the ore. However most rocks don't even have any ore so heat cannot change rocks so that metal detectors can detect them.

What are the benefits of owning a heat detector?
A heat detector is a good addition to the smoke alarm. It will help to detect a heat source that is growing in case the smoke alarm in the home is not functioning.
What is pir?
A PIR normally refers to a passive infra-red detector. These are the detectors typically used in security systems to detect movement of people. They are normally found with a small translucent window in the front of the detector. The detector works by measuring the infra-red radiation (heat) from the field of view in front of the translucent lens. When the radiation levels change or a heat source moves, the output of the detector is triggered. Normal security use will detect a person moving in the field of view but they can be far more sensitive and detect movements of far smaller animals.
What happend when a convection current detector came near a heat source?
When a convection current detector comes near a heat source, it will detect the movement of air or fluid caused by the temperature difference. This movement creates a convection current around the heat source, which the detector can measure to indicate the presence and intensity of the heat source.
What is a heat detector?
A heat detector is a device designed to sense a significant increase in temperature, typically above a certain threshold. It is commonly used in fire alarm systems to detect fires in areas where smoke detectors may not be suitable, such as kitchens or areas with excessive dust. When the temperature rise is detected, the heat detector triggers an alarm to alert occupants of potential fire hazards.
What are Two type of heat detectors are?
They are: -Rate of Rise -Fixed Temperature Rate of rise detectors can be adjusted to different temperature settings to which detect heat. Once the temperature in that area reaches your chosen point, it will activate the heat detector. Fixed Temperature is when you buy a heat detector, it only has one fixed detection point on it. So you cannot adjust this.
What are important about heat detector?
They detect heat instead of smoke. They are widely used in boiler houses, kitchens where a lot of steam and smoke is created. If a smoke detector was installed in this application, then there would be a lot of false alarms. So instead, they detect the heat intensity of a fire which will set off the fire alarm. They are also less likey to be set off by accident. Spiders, dust, deodrant etc sets off smoke detectors quite frequently. this does not happen in heat detectors.
What is the function of a heat detector system?
To detect heat from/of a fire or something which is dangerously hot in cerrtain apllications. They are connected to fire alarm system where when the heat detector detects heat, it activates the fire alarm causing the need to evacuate. These type of devices are used in applications where smoke detectors would not be practicle. For example, kitchens, boiler houses etc.
What is the distance between heat detectors?
5M Detector to Detector
How can radiation detect a fire?
Radiation detectors can sense changes in temperature caused by a fire. When objects burn, they emit heat that can be picked up by sensors in the radiation detector. This increase in temperature triggers the alarm on the detector, alerting users to the presence of a fire.
How does a fire alarm detect smoke?
Smoke detectors work in several ways. A point to point smoke detector detects smoke when the beam projected by the transmitter is obscured in a measurable way and detected by the receiver. A photoelectric detector sees smoke particles inside the detection chamber of the smoke detector because light inside the chamber is scattered in a measurable way. An ionization smoke detector detects smoke because the smoke particles change the 'charge' on the detection plate inside the smoke detector.
Do pets cause interference with ademco heat detectors?
I am not personally familiar with the ademco heat detector, but I have done some research and have found that this head detector is pet immune, and pets do not cause interference with this heat detector security system.
What happen when the convention current detector came near a heat source?
When a convention current detector comes near a heat source, it typically detects an increase in temperature due to the heat generated by the source. This change in temperature can cause a variation in the electrical resistance or current within the detector, potentially triggering an indication of the convection currents produced by the heat. As warm air rises and cooler air moves in to replace it, the detector may register changes in air movement or temperature gradients, providing insight into the convection process occurring around the heat source.
