What Are The Fire Alarm PCB Monitoring Systems?
There are three basic fire alarm PCB monitoring systems: photoelectric, ionization, and combination alarms. Each of them works to detect fire but in different ways. Each of the PCB monitoring types is discussed in the following.
Photoelectric fire alarm PCB is good for identifying smoldering fires. smoldering fire, slow flamingos produce different kinds of smoke than a flaming fire. This type of PCB utilizes a beam of light.
The beam of light is transferred into a chamber. If a fire accident, the produced smoke goes into the chamber. The chamber reflects the light towards the sensor and then it triggers the alarm to buzz.
Ionization fire alarm PCB is suitable for identifying fast flaming fires. There is radioactive material inside the alarm board. The material is positioned between two plates that are electronically charged.
As a result between the two plates, there is a constant ionized current. In case of a fire incident, the produced smoke goes between the two plates among the ionized current. Consequently, it breaks the ionized current and sets the alarm off.
Combination alarm PCB is the merged version of both the system of photoelectric and ionization fire detecting alarm PCB technologies. As it is a combination PCB technology, it doesn’t work as great as the other two PCB works individually. A single unit of fire alarm boards works more efficiently than the detection method of the combination PCB system.
What Are The Components Of Fire Alarm PCB?
A fire alarm PCB is made of several components. The components vary from one board to another according to the requirement of the application. You can choose the components of your board and customize it, but there are some basic components of a fire alarm printed circuit board which is as follows.

Components Of Fire Alarm PCB
Why Do We Use Fire Alarm PCB?
It is really helpful in detecting smoke, fire, or other incidents. It is very useful in preventing people’s injuries and property damages. The boards are able to detect the fire or smoke instantly and begin the buzzer or siren sound immediately.
It is very necessary to prevent fire occurrences before it spreads out. The fire alarm PCBs can recognize the smoke at the perfect time. That is why we can see a wide range of fire alarm board uses in building sectors and in different industries.
Use Of Fire Alarm PCB
The device activates the alarm as soon as it can detect the reaction of heat detectors and smoke as further precautions. It can be involved in a home security system as well. Other versatile security-related devices like detectors, intruder alerts, etc use fire alarm PCB in their system.
How Does Fire Alarm PCB Work?
The fire alarm PCB working procedure is based on the thermistor used in the circuit. The circuit identifies and indicates the rise of temperature in an enclosed area beyond a certain value.
The LED indicates the temperature increasing by turning on. You can use a cooling system as well to reduce the temperature to its neutral value. The load or cooler automatically turns on if the temperature goes to a certain point without any monitoring system.
You can use an operational amplifier as well along with a negative coefficient thermistor to turn on the operation instead of using LED. The fire alarm PCB uses a thermistor as a temperature sensor. The thermistor is more cost-effective than most other temperature sensors.
Thermistors largely show temperature vs nonlinear resistance characteristics. Correction is a must needed in applications that need a linear response.
The input to the NPN transistor switches when the temperature changes. Then the output the NPN transistor provides helps for the LED indicator.
You can get more accurate results if you use a digital temperature sensor in your fire alarm PCB instead of an analog one. It works in a very delicate way to provide the best functionality.
You will get a better idea by watching the following video.

Watch the following video.
What Is The Manufacturing Process Of Fire Alarm PCB?
Fire alarm PCB uses a thermistor for having a temperature control system in it. The manufacturer needs to go through a specific process to manufacture these PCBs. The manufacturing process of five steps is as follows.
- Estimating the fire alarm PCB design
- Gathering the components of the fire alarm PCB
- Making the assembly of the fire alarm board
- Connecting circuits and soldering them
- Selecting the vias’ positions and drilling them
- Etching the copper from the board
How Shall We Produce Fire Alarm PCB Assembly?
Assembling a fire alarm PCB perfectly is very important as the functionality and efficiency of the PCB depend on it.
Fire Alarm PCB Assembly
To produce a fire alarm PCB assembly, first, you need to collect all the components that are required for your application. Then you have to place all the necessary components in their specific places. Make sure the pads, tracks, and holes are according to the requirement of your application.
After positioning the components and checking everything required, the manufacturer starts to solder all the components on the board. Finally, you will have your fire alarm PCB assembly prepared.
How To Connect A Control Panel To A Fire Alarm PCB?
There is a control panel connected to every fire alarm PCB. It is designed to receive information from devices to report and detect fire. It also monitors the operational integrity of the device.
The control panel of a fire alarm PCB provides automatic control of the equipment. It transmits necessary information about the fire occurrence to take precautions.
Control Panel Of Fire Alarm PCB
The control panel is generally semi-flush or surface mounted. To connect the panel to the PCB, it should be placed internally on the printed board. Extreme temperature, humidity, and physical abuse can reduce the efficiency of the board.
And so it should be located in a safe place to provide the best functionality. It should be in an easily accessible location as well. The manufacturer needs to be very careful and delicate while connecting the control panel to the fire alarm PCB.
How Does The Power Supply System Work In Fire Alarm PCB?
We need a well-balanced power supply to regulate a fire alarm PCB properly. A tiny change in the voltage supply can seriously damage the performance of the board. Variation in the voltage supply to the PCB can change the transistor biasing applied in the section of fire sensing.
Power Supply Of Fire Alarm PCB
The most common and basic power supply system used for fire alarm PCBs is a regulated power supply of 9V/500mA. It works for almost every type of fire alarm board. The power supply system functions in a specific way.
The primary voltage is 230V and the secondary voltage is 12V in Transformer T1 and it is a 500mA step-down transformer. D1 does the rectification job which is a 1A bridge. The C1 capacitor clarifies the output of the rectifier and the C2 capacitor works for AC by-pass.
There is also a fixed positive voltage regulator of 9V that is IC1 (7809). The manufacturer connects the rectifier and filter output to the 7805 input. Then the system provides a steady and regulated 9V output.
This power supply system is attached to the PCB to provide its required power. There is an ON/OFF switch S1 controlling the power supply to the PCB. And F1 is a safety fuse of 500mA.
What Is The Schematic Of Fire Alarm PCB?
The schematic of the fire alarm PCB is very crucial and it is a delicate schematic. First off the manufacturer wires the Timer IC NE555 (IC1) in the character of an unstable multivibrator that swings in the audio frequency band. Then the T1 and T2 transistors are switched and they drive the NE555 (IC1) multivibrator.
Schematic Of Fire Alarm PCB
The manufacturer then connects the IC1 output to NPN transistor T3. It makes the loudspeaker (LS1) produce sound. The IC1 frequency is mostly dependent on the rates of capacitor C2, resistors R5, and resistors R6.
The thermistor is wrapped in mica tape to stop it from melting. A regulated power supply of 6V-12V is required to run off the home fire alarm PCBs. We use LED1 to indicate the switch-on power of the fire alarm board.
How Does Fire Alarm PCB Use Thermistor?
The thermistor is a very important component for a fire alarm PCB. The main component of the PCB is the thermistor. This thermistor detects the fire in an alarm.
It is mainly an NTC thermistor of 10k ohm. It has 10kohms resistance at room temperature. We need to connect another resistance to this thermistor to generate a voltage divider circuit.
The voltage divider circuit is connected through a diode to the thermistor. When the transistor is put on the ground, the buzzer switches on then. Increasing the temperature causes an increase in the buzzer sound as well.
Fire Alarm PCB Using Thermistor
The thermistor resistance goes down when the temperature rises. Not to mention that the temperature rises in case of fire occurrence. This temperature expansion reduces the thermistor resistance.
The voltage divider output rises when the thermistor resistance reduces. This affects the inverting input of the Op-Amp as the voltage divider output is supposed to be on it. And so its value will be bigger than the inverting input value.
Consequently, the Op-Amp output becomes very high. The high output turns on the buzzer of the fire alarm. That’s how the fire alarm PCB operates.
How Does Fire Alarm PCB Produce Siren Sound?
The fire alarm PCB rings a siren sound if there’s any fire incident to alert people. The most common fire alarms alert people for fire occurrence with a buzzer. But this one is quite different because it utilizes basic PCB components to produce a siren sound.
Siren Sound In Fire Alarm PCB
Many integrated circuits can produce siren sounds. But we prefer to utilize basic electronics components like transistors, capacitors, resistors, etc to generate the siren effect.
Using the basic components will make the process much more beneficial for you. You can analyze the circuit and gain more knowledge. You will realize the internal operation of the board as well.
What Is The Signal Circuit In A Fire Alarm PCB?
Signal line circuit or SLC plays a vital role in fire alarm PCBs. SLC mainly transmits signals. The signal line circuit also supplies power to the output and input modules.
Signal Circuit In Fire Alarm PCB
It carries signals backward and forward in the control panel. It carries signals back and forth between each of the output and input devices connected to the printed circuit board as well.
What Type Of Surface Finishes Do You Use On A Fire Alarm PCB?
Surface finishing is a very important process for every kind of fire alarm PCB. A good surface finish can increase the durability and longevity of the board. The surface finish protects the board from external damages.
Surface Finish In Fire Alarm PCB
How Do You Etch Copper From Fire Alarm PCB?
Etching is a very important step in fabricating fire alarm PCB. In this process of etching, the manufacturer declutters the unrequired copper from the printed circuit board. To etch copper from a fire alarm board, several chemicals are used.
Etching In Fire Alarm PCB
The most common chemical that the manufacturer uses to etch copper from a board is Ferric Chloride (FeCl3). It is a very toxic and harmful chemical. You must need to be very careful while etching copper from a PCB.
What Is The Cost Of Fire Alarm PCB?
There is no fixed pricing of fire alarm PCBs. It varies from one type of board to another. Different manufacturing companies cost them differently as well.
Cost Of Fire Alarm PCB
The cost mainly depends on the materials, the components, surface finishes, requirements, etc. if you customize your fire alarm board, it will cost you according to the customization.
How Do You Choose The Right Manufacturer Of Fire Alarm PCB?
Choosing the right manufacturer for fire alarm PCB is as important or else the total project can go in vain. You may check some facts while choosing the manufacturer for quality assurance.
The manufacturing company should have a group of experts to produce these PCBs. As the manufacturing of the boards is very delicate, they should have advanced technologies. Make sure they have enough knowledge about what they are working on.
