Duct Smoke Detector
The Duct smoke detector detects smoke and combustion products in air moving through HVAC ducts.
This device prevents air handling systems' smoke recirculation in areas.
It can be connected to the fire alarm system or the BMS system.

What is the contactor?
A contactor is an electromechanical switch whose function is to make or break the connection between the power supply and the load.
It consists of Coil, Spring, Steel Core, Static Contacts, and Dynamic Contacts.
It is electrically controlled by applying a voltage to its coil and is usually powered much lower than the switched circuit.
It is most commonly used with electric motors and lighting applications.

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.

Types of Traps in Western Water Closets π½
In order to form a seal and prevent (trap) unwanted gasses from escaping from the sewerage, the trap retains some water. π¨π§
For an S-Trap toilet, the soil drainage pipe exits the toilet through the floor.
While in a P-Trap, the soil drainage pipe exits through the wall.
The easiest way to remember this is by remembering the direction of drainage water flow, as shown in the attached photo of this post.

Importance of Coloring Embedded Conduits and outlets in Concrete Slabs
Itβs preferable before installing embedded conduits and outlets in the concrete slab to use a pre-colored conduits and outlets, but if they are not available, you can use spray paint to identify each systemβs outlets and conduits.
This will help the electrician to identify each outlet for which system, Ex: Lighting - power - Fire Alarm - CCTV...etc.
Because if all conduits and outlets with the same color (Ex: White), so it will take time from your team to differentiate between each systemβs conduits & outlets, which increase the cost of manpower and time.

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.

Understanding the Data of MCCB
MCCB is an abbreviation for Modled Case Circuit Breaker.
MCCB can be used as the main breaker of a panel, the breaker of a branch circuit, or both in the same panel.
There is a lot of information available on the body of its enclosure.
So, we summarized this information, as you can see in this photo.
