Maintain & maintain fire protection system

The need to maintain the fire protection system

For apartment buildings, high-rise buildings or business places, they are required to be equipped with a standard fire protection system.

Depending on the characteristics of each type of project, customers can choose the corresponding product. The fire protection system after a period of use will need to be serviced and maintained so that the smallest damages can be promptly inspected and handled.

The regulations on maintenance of fire protection systems have been clearly stipulated by law and are required to be followed by individuals and businesses to ensure safety for everyone.

Regulations on fire protection maintenance for automatic fire alarm systems

The fire protection system will include two separate parts: the automatic fire alarm system and the automatic fire extinguishing system. Each part has a different structure and function. One of the important requirements for an automatic fire alarm system is high reliability and needs to operate at the right time.

Just a small malfunction or a false alarm from the system can cause huge damage to people and property. The cost of installing an automatic fire alarm system and overall automatic fire suppression system is very large, so any small problem that occurs needs to be detected and maintained promptly and promptly. The state has introduced specific requirements and regulations when maintaining fire protection systems

For automatic fire alarm system

To ensure the safety of everyone, there are provisions for inspection and maintenance of mobile fire protection systems. Circular No. 52/2014 was issued by the Fire Prevention Police Department and the Ministry of Public Security. Excerpt from section 7, regulations on maintenance and maintenance of fire alarm and fire fighting systems:

Article 26 of the code regulates the preservation and maintenance of automatic and semi-automatic fire alarm systems including:

1. After being installed, the automatic fire alarm system needs to be tested on the entire system. The automatic fire alarm system is only allowed to be put into operation when the test results fully meet safety standards and the designer's requirements.
2. After being put into operation, the automatic fire alarm system needs to be periodically checked twice a year. When checking, it is necessary to retest the functionality of the entire system.
3. Regulations for periodic maintenance of automatic fire alarm systems: Depends on the operating environment, system installation and manufacturer's regulations. At least every 2 years, maintenance of the entire system is required, in which the fire protection system maintenance process includes steps to check the operating level of the equipment.

For automatic fire suppression systems

Regulations on preservation and maintenance of automatic fire extinguishing systems are taken from article 27 including:

1. Once installed, the automatic fire suppression system must be tested throughout the entire system. The product is put into use when the results of fire protection equipment inspection show that the results fully meet the manufacturer's requirements and relevant standards. As required, this system needs to be periodically inspected and maintained once a year or according to the manufacturer's instructions.
2. During maintenance, except for equipment such as sprinkler heads and heat detectors... that only operate once, the remaining equipment must be checked in detail for quantity, quality and operability.
3. The process of checking and maintaining the automatic fire alarm system complies with TCVN 6101, TCVN 7161, TCVN 6305 and other manufacturer's standards.

Fire protection system maintenance process

Just like maintenance, fire protection system maintenance is an extremely important issue, especially for apartment complexes and high-rise buildings. The fire protection system maintenance process helps us check and detect damaged equipment, conduct technical care, repair and replace parts to maintain and restore smooth operation. but of the system.

Check the fire protection pump system

Pumps in fire protection systems are usually several types of pumps with large capacity. This product line is often equipped for fire protection systems of high-rise buildings and apartments. The machine is used to supply water with high pressure to automatic fire extinguishing systems or fire hydrants.

There are three main types of pumps used in fire protection systems: Diesel pumps, electric pumps and diesel pumps. Pump inspection is quite important and must take place periodically. Because in some special situations the pump may be clogged, damaged or unable to absorb water... this will affect the entire fire protection system.

The fire protection system maintenance process for pumps includes 5 basic steps:

• Step 1. Make a general observation and start checking whether the screws at the connection points, joints, and machine parts are screwed tightly or not. Especially the screws in the flywheel area for trailer wheels. Note, the place to store the battery must be dry, the rack must be sturdy and not move when the machine starts.
• Step 2. Next, check the fuel, coolant for the pump and lubricating oil. Everything must reach the prescribed level and not leak outside.
• Step 3. Check the electrical transmission system and electrical cable system connected to the battery.
• Step 4. Start the fire pump system and consider details such as the priming pump legs.
• Step 5. At the pump location, check the operability of the accompanying auxiliary equipment.

Check the main fire pipes leading to the floors

For high-rise buildings, to connect the fire protection system between floors, long and fixed pipelines are required. Fire pipe maintenance is part of the fire protection system maintenance process. Like other types of equipment, after a period of non-use, the duct system can become clogged and corroded. That's why we need to check and maintain periodically.

Maintenance of the water supply pipeline system requires the following steps:

• Step 1. Check the condition of the main water pipe shutoff valves supplying the floors and check if the water pressure gauge is working.
• Step 2. Pump a mixture of clean water and calcium descaling chemicals into the pipe. Submerge ½ of the large tube and let it soak for about 30 - 60 minutes.
• Step 3. Drain the old bleach solution and inject new water.
• Step 4. Check the pipe for leaks and fix it if there is damage.

Check the automatic fire sprinkler system

The Sprinkler automatic fire suppression system uses a closed discharge nozzle system and is always in permanent mode. In case of fire, through the heat sensor system, water will automatically be sprayed out. This system is only capable of extinguishing fires in certain points or spaces and is often used for places with low or medium fire risk. The Sprinkler automatic fire suppression system always has water in the pipes and is maintained at low pressure.

To clean and maintain the Fire Protection Sprinkler system, you need to go through the following steps:

• Step 1. Remove the Sprinkler nozzle from the system and clean and check the sprinkler nozzle details.
• Step 2. Descale the plumbing system supplying water to the sprinkler head.
• Step 3. Maintain valve and pump control systems.
• Step 4. Check in detail the pump's ability to operate in the Sprinkler automatic fire suppression system.

Check the wall fire suppression system

The regulations on maintenance of fire protection systems will include wall fire suppression systems. Wall fire suppression systems often appear in large projects.

Normally, the pipe system will be constructed close to walls, hallways, emergency stairs or underground parking areas. The wall fire suppression system is connected to an automatic pump and lock valve. This is a semi-automatic fire extinguishing system. When a fire occurs, you need to open the valve at the fire protection cabinet and water will immediately be released under high pressure.

Steps to maintain a wall fire suppression system include:

• Step 1. Turn on the pump to run the system for about 10 minutes and perform a check on the entire system.
• Step 2. Check the pump for overheating or overloading.
• Step 3. Check devices such as volt meters and power voltage ammeters.
• Step 4. Consider the operating mode of the fire protection cabinet and check the main switch and pump control switch.
• Step 5. Check the switching ability of the timer and relay.
• Step 6. Check the pipe system on the floors to assess the level of leakage and check the operation of the pressure gauge. Note, for diesel pumps, you need to check the temperature and speed of the machine and see if the oil is leaking.

Check the outdoor water system

Outdoor hydrant systems are often used in semi-automatic fire suppression systems. The process of maintaining the mobile fire protection system will include the outdoor hydrant system. The water column also needs to be checked periodically every 6 months to ensure the column always has water available without drying out.

When checking and maintaining water columns, pay attention to the following steps:

• Step 1. Preliminarily check the outside of the water pipe to see if there is rust or if the connector is damaged.
• Step 2. Open the valve and release the non-pressure water test to ensure there is enough water in the cylinder.
• Step 3. Remove excess water in the tube and re-inject new water.

Check the control valves

Fire valves are an important device to create a complete fire protection system. This device is often installed inside or outside the building, and is responsible for helping open and close the water supply valve for the fire sprinkler system when there is a fire. Control Valves must always be in a stable operating state so that they can be used immediately when needed.

Valve control maintenance process includes:

• Step 1. Check the ability to open and close the valves in the valve holes.
• Step 2. Apply lubricant to each valve to ensure the valve always operates smoothly.
• Step 3. Check the grout, if damage appears, replace the grout.

Check hand-held fire extinguishers and fire balls

Fire extinguishers or fire balls are certainly no longer strange to us. These are the most popular fire protection equipment on the market. Fire extinguishers can be installed and used for many different types of projects. It has a quite compact design, is simple to use and can be used anywhere.

According to regulations, the maintenance period for fire extinguishers is every 6 months and the maintenance period is 1 year. Fire extinguishers or fire alarms when installed outside will be at risk of rust, damage to the safety pin or hardening of the powder. Maintaining the fire protection system is mandatory. Complying with the laws on fire protection system maintenance also contributes to making the lives of users safer.

Inspection and maintenance of fire extinguishers/fire balls must be performed by professionally trained technicians. The process includes the following steps:

• Step 1. The technician needs to conduct a preliminary inspection of the exterior, checking the spray nozzle and safety latch.
• Step 2. Check the pressure gauge of the tank/balloon.
• Step 3. Check the amount of gas and whether the powder inside is lumpy.
• Step 4. Preliminary finishing and lead sealing.

Check the fire prevention and alarm system

Fire prevention and alarm systems are often installed in high positions on walls, usually in corners or ceilings. This device is often quite small and easily forgotten. Fire alarms are often installed in automatic fire protection systems. Regularly maintain the fire protection system to ensure that when an incident occurs, damage can be minimized. We will share with you a few simple ways to check and clean fire prevention and alarm systems.

Need to prepare some items before cleaning such as ladder, electric pen, paint brush and dry towel. After removing the fire detector button, preliminary cleaning can be done with a paint brush to remove dust. Then use an electric meter to check the voltage (voltage ranges from 18 - 24V). After checking and cleaning, we proceed to reassemble the device as before.

Professional fire protection system maintenance unit

When the need to install fire protection systems increases, it also leads to the birth of fire protection system maintenance companies. Too many options make customers not know which company to choose. The process of maintenance and maintenance of fire protection systems requires technicians to master specialized professional knowledge as well as the design, structure and features of each fire protection equipment.

In particular, they need to understand safety issues and risks affecting the lives, property and production and business of individuals and businesses when using fire protection systems. Therefore, customers need to pay attention to finding a reputable and experienced service provider.
