How security temperature detector works?

Temperature detector is also called freeze sensor, it works with home/commercial security alarm system, provides function of monitoring environment temperature. The detector supports programmable temperature warning and alarm thresholds.

For example, when it has been installed inside, and the environment temperature drops below 0 degrees Celsius (33.8 degrees F), then the temperature/freeze alarm will be triggered instantly. The alarm monitoring center will get notified, also you will receive instantly temperature alarm alert through text message (SMS) or email.

You can place the temperature sensor in areas where require temperature monitoring to monitor refrigerator, freezer and outdoor temperatures. It also can be used for early warning of pipe burst. Burst pipes can mean a massive headache – damage, hassle and expensive repair bills. The freeze sensors detect low temperature conditions and provide early warning, before the freeze. These detectors can alert you to other issues, too, like a malfunction in your furnace.

Temperature sensor can be used to detect heat or extreme low temperature. The detector measures the temperature of the air around it and have a normal range to which it doesn't react. If the environment temperature rises above the normal range, the detector will set-off an alarm. Some temperature sensors can record temperature changes degree by degrees, therefore actions may be taken when certain levels are reached, but most are simply trigger alarm warning when the temperature moves outside their normal range.

High temperature detectors are used as fire alarm detector (also called heat detector). They are usually mounted high in a room and detect the temperature change when the air temperature at ceiling level reaches about 140 degrees F. Since heat rises in a room, a fire burning at floor level will quickly raise the temperature at the ceiling to this critical level. Heat from a stove or other warming device will not get the air up to critical temperature unless these appliances are left on too long and become a fire danger. Temperature sensors do not detect the smoke, only to heat, so they make good fire detectors in kitchen areas where come occasional smoke is common and smoke detectors can not be used.

Opposite to high temperature detector, low temperature sensors are mostly used for protection against freezing. It detects when the inside temperature drops below 41 degrees F and then immediately triggers an alarm. The security system may then be programmed to shut off outside water system to prevent pipes freezing. It may also activate de-icing system on driveways, roofs and rain gutters. Low-temperature detectors can also be useful in outbuildings where they can trigger alert or warning to animals or machinery when the temperature falls too low because of failed heaters, windows or doors left open, or other mishaps.
