What is fire suppression system & how it works?
A fire suppression system is an engineered group of units that are built to extinguish fires through the application of a substance. Most commonly, a fire suppression system has built-in components that detect fires at the beginning stages through heat, smoke, and other warning signals.
What is installed in the ducts and mechanical passage ways to prevent the fire from spreading *?

Ansul requires their activation cartridges be hydro-statically tested and recharged every twelve years, but due to the cost of this service, it is more economical to replace the cartridge. Q: What is a purge test?
What are the two main types of fire protection systems?
Fire-protection systems fall into two main categories — passive fire protection and active fire protection. Passive fire protection involves the use of building components to control or limit a fire. Walls, floors, and ceilings can be designed and constructed to resist the passage of fire and smoke.
What are the basic fire protection systems?
Fire protection systems are standard building features that either actively or passively help to control the amount of damage that can occur to a building and protect its occupants in the event of a fire. Active fire protection systems include features such as automatic fire sprinklers and fire alarm systems.

What is the difference between fire protection and fire suppression?
Fire protection reduces damage and helps to safely evacuate a building. Fire suppression systems are intended to extinguish the flames.
What are the risks of mechanical ventilation?
What are the risks of mechanical ventilation? The main risk of mechanical ventilation is an infection, as the artificial airway (breathing tube) may allow germs to enter the lung. This risk of infection increases the longer mechanical ventilation is needed and is highest around two weeks.
How does a fire suppression system shut down electrical equipment?
The fire suppression system is master to the shut down of electrical equipment. The system will have a micro switch to activate a shunt trip breaker. In any case all electrical equipment under the hood must shut down.

What happens when smoke enters a fire alarm circuit?
In case of fire when smoke enters the chamber, the current flow between two electrodes reduced due to ionize air. The drop in the current flow is used to trigger the sounder and alarm circuit.
How is a fire alarm connected to a control panel?
In a conventional fire alarm system, all devices such as detectors, sounders and call points are connected to the control panel through separate wire or cable instead of shared one. In other words, the first end of the wire is connected to the detectors and second one to the control panel.
