Portable Fire Extinguisher Hanging Height

A portable Fire Extinguisher is an item of equipment to extinguish a fire.

It is effective only for the type and size of a fire it is rated for.

As per NFPA 10, Clause no. 6.1.3.8, the top point of the extinguishers has two heights for installation, as its installation height will depend on the weight of the fire extinguisher.

If the weight of the fire extinguisher is less than 18 Kilograms, the maximum distance from its top to the FFL will be 1.5 meters.

But, if the weight of the extinguisher is more than 18 Kilograms (except the mobile or wheel type), the maximum distance from its top to the FFL will be almost one meter.

Where 40 lb almost equals 18 Kg.

In all cases, the distance from the bottom of the extinguisher to the FFL shall be more than 10 Cm.

Diesel Pump in Firefighting System

The firefighting pump room is the heart of a fire station.

It is equipped with the firefighting resources necessary to ensure the safety and well-being of the community.

It will have multiple types of fire pumps.

May you ask yourself on your first visit to a firefighting pump room one important question: πŸ€”

Which one of these pumps is the diesel firefighting pump? πŸ™„πŸ™„

Simply, the pump that has an exhaust in the FF pump room will be the diesel pump.

So whenever we have a pump with an exhaust line, it’s a diesel pump. 😎

Siamese Connection Installation Height

The proper installation height of a Siamese connection is an essential factor that must be considered.

This is to ensure the firefighting systems operate as intended.

As per NFPA, the installation height must be a minimum of 0.5m to a maximum of 1.2m from the finished floor level.

Do you know that sprinkler systems can be failed because of corrosion?

Corrosion can cause serious damage to your sprinkler system over time. πŸ”₯

It is the gradual destruction of a metal due to chemical reactions with its environment, such as water, oxygen, and salts.

When corrosion occurs in your sprinkler system, it can cause the pipes to become clogged, leak, or break, leading to costly repairs.

In order to prevent corrosion from causing damage, regular inspections and maintenance are necessary.

In this file, you will learn the following:

βœ” Discuss the problems corrosion causes in fire sprinkler systems.

βœ” Identify the causes of corrosion.

βœ” Take an in-depth look at the current state of corrosion technology.

βœ” Evaluate the economic impact that corrosion has on fire sprinkler systems.

Relay in BMS Systems - Read it For Free

A relay plays an important role in controlling and monitoring the various components of a building management system.

It acts as a switch that transmits signals from one component to another.

With a relay, building maintenance staff can easily monitor and control HVAC, lighting, and security systems from a central location.

However, the relay in building management systems is not a one-size-fits-all solution. Different relays may be required depending on the type of building and its unique needs.

In this blog post, we will delve deeper into the role of relays in building management systems.

FCU Hookup and its Valves

FCU hookup, or fan coil unit hookup, is essential to HVAC systems in commercial and residential buildings.

It involves the connection of a fan coil unit to the building's water supply, which allows for the circulation of hot or cold water to maintain a comfortable ambient temperature.

Valves play a crucial role in the FCU hookup process, controlling the flow and temperature of the water as it circulates through the unit.

So, we released a new blog post that will delve into the different types of valves used in FCU hookups and how it affects the performance of the HVAC system.

Motor Control Center Handbook - Free Download

Motor control centers, or MCCs for short, are essential in the automation and control of industrial processes.

Providing the means to both distribute and control electrical power to motors, the MCC serves as a centralized hub for managing complex electrical systems.

As such, the MCC plays a pivotal role in the smooth functioning of industrial operations, and any malfunction or failure can result in significant downtime and revenue loss.

With the high stakes involved in managing industrial processes, it is crucial to have a comprehensive understanding of the MCC and its workings.

Monitor Modules (MM) in Fire Alarm Systems

Monitor modules (MM) are essential components of an addressable fire alarm system.

We consider it as an input module.

They allow non-addressable devices, like sprinkler flow switches, Tamper Switches, or loops of standard heat detectors, to be monitored and connected with the main fire alarm control panel (F A C P)

The attached photo shows the common applications of the monitor modules.

Circuit Breaker Types in Low Voltage Systems

We have three different types of circuit breakers as follows:

1- Miniature Circuit Breaker or MCB:
Usually, we find it in the final electrical distribution boards; it can be one pole, two poles, three poles, or four poles.

Also, we can use it as a protection circuit breaker in the control panels.


2- Molded Case Circuit Breakers or MCB:
Usually, it will be as the main breaker in the sub-main panels or the breaker of the branch circuits in the main panels.
It has a higher short circuit capacity than MCB.


3- Air Circuit Breaker or ACB:
Usually, it will be the main breaker in the main panels or MDB.
It has higher short-circuit capacity than MCB & MCCB

Shunt Trip Coil

A shunt trip coil is an optional accessory in a circuit breaker that mechanically trips the breaker when power is applied to the shunt trip terminals.

The power for the shunt trip does not come from within the breaker, so it must be supplied from an external source.

Its most common application is when we need to control switching off the power of a panel by a feedback signal from the BMS system.

πŸ”₯πŸ“š FACTUAL DATA ALERT!πŸ“šπŸ”₯

Did you know using an electrode dryer before welding black steel pipes is crucial?

Here's why:

πŸ” Moisture can negatively affect your welding.

πŸ’¦ Drying Low Hydrogen electrodes before use ensures high-quality welds.

πŸ’» The primary purpose of the electrode Dryer is to keep the electrodes dry and prevent moisture absorption.

πŸ“ The composition specifications of solid welding electrode wires and rods are vital.

πŸ‘· Pre-preparation of pipes before welding improves the quality of the weld seam.

πŸ’ͺ Using a medium-coated electrode is perfect for mild steel and can help avoid undercut and excessive convex fillet.

Remember, welding specification of carbon and alloy steel piping is essential. 😎

What is the reason for painting this metal duct red?

The photo shows a black steel duct that can be used in different applications like kitchen hoods.

As this duct will not be insulated, we paint the outer surface of black steel ducts with red oxide coating.

This coating acts as a preparatory or protective coating that prevents rust formation on the ferrous metal surfaces exposed to humidity and air.
