Rate Compensated Heat Detectors Working Principle
Rate compensated heat detectors are designed to initiate an alarm when the temperature of the surrounding air reaches a predetermined level, regardless of the rate of temperature rise. Rate Compensated…
Fixed Temperature Heat Detector Working Principle
A heat detector is a fire alarm device designed to respond when the convected thermal energy of a fire increases the temperature of a heat sensitive element. The thermal mass…
What is Partial Stroke Test?
In all of our activities, safety is one of the prime points under consideration. The same is true when we deal with industrial processes, mainly when process automation is increasingly…
Rate of Rise Thermal Detectors Working Principle
A heat detector is a fire alarm device designed to respond when the convected thermal energy of a fire increases the temperature of a heat sensitive element. The thermal mass…
What is Fire Alarm System?
A fire alarm system has a number of devices working together to detect and warn people through visual and audio appliances when smoke, fire, carbon monoxide or other emergencies are…
Electric Motor Actuator Parts
The electric actuator uses an electric motor to provide torque to operate a valve. They are quiet, non-toxic and energy efficient. However, electricity must be available, which is not always…
Advantages and Disadvantages of Valve Actuators
A valve actuator is the mechanism for opening and closing a valve. Manually operated valves require someone in attendance to adjust them using a direct or geared mechanism attached to…
What is Manual Call Point (MCP) ?
Manual Call Point is a device for the manual initiation of an alarm. Manual fire alarm activation is typically achieved through the use of a pull station (term used in USA…
What are Linear Heat Detectors?
Linear Heat Detection (LHD) (also known as Linear Detection Wire or Linear Heat Detection Cable or Linear Heat) is a very commonly used method of fire detection. It can detect…
What is Gas Leak Detection System ?
This article refers to issues surrounding the detection of leaks and gases and what type of containment Gas Leak Detection System have been designed to manage unplanned releases. A gas…
