A functioning business may have all it's necessary ingredients to make the business a success. However, failing to have the necessary fire safety could accidentally bring it all to an abrupt halt.

 
 

 
 
   
 

Heat comes in all shapes and sizes. Unfortunately we cannot always see it. To feel a potential hazard is another story, and could be fatally worse than hearing of one. So, keep calm and stay warned with our range of reliable heat detectors.

How do heat detectors work?

There are two types of heat detection methods:

Fixed Temperature temperature increases to a predetermined point causing the detector to be triggered.
Rate-Of-Rise rate at which temperature rises is compared to the detectors manufactured rate of temperature rise operation and the difference is calculated to determine detector status.

Fixed temperature detectors rely on the mixture of two or more metals combined known as eutectic alloy. This alloy because of its mixture has a low melting point. When ambient temperature reaches the eutectic temperature the alloy changes from a solid to a liquid. Fixed temperature detectors can also operate using a single thermistor a type of resistor whose resistance is dramatically affected by temperature to effectively detect changes in ambient temperatures.

Rate-of-rise temperature detectors most commonly make use of thermistors known as thermocouples to distinguish change in ambient temperatures. A thermistor is a type of resistor whose resistance is dramatically affected by temperature. A rate-of-rise detector can have one or two thermistors one for monitoring heat radiation and the other for monitoring ambient temperature. When a rise in heat is identified the rate of the risen temperature is calculated by the thermistor responsible for the ambient temperature and compared to the thermistor responsible for the heat radiation. If a rate of 1.6C per minute is picked up the detector is triggered.

Installation:

Heat detectors are most commonly installed in residential areas such as Kitchens, bedrooms and, hallways. It is recommended to install a heat detector anywhere a smoke detector cannot be installed. It is recommended not to replace smoke detectors with heat detectors. Areas where heat detectors should not be installed include: Laundry rooms, garages, and sheds. Due to the type of technology used by the detector rate-of-rise detectors should not be installed too close to stoves, ovens or any area that is exposed to rapid rising heat. For areas like those, fixed temperature heat detectors should be used.

  Series 65 Heat Detector Orbis Heat Detector Discovery Heat Detector XP95 Heat Detector
 
Description The Series 65 heat detector uses rate-of-rise heat detection technology to warn for potential fire hazards. It is reliable for picking up a suspiciously sudden rise in heat and is a favourite in areas that can be potentially smoky or dirty. The Orbis heat detector makes use of a single thermocouple to distinguish the presence of heat. The Orbis range comes in a variety of models capable of detecting fixed-temperature, rate-of-rise temperature or both simultaneously.
 
The Discovery heat detector makes use of only one thermocouple to monitor ambient temperatures around the device.
 
The XP95 heat detector uses an inner thermistor (thermocouple) that is compared to the outer ambient temperature to distinguish a final result. Its housing is designed to limit low air-flow and maintain good detection functionality.
