Fire alarm system structure

Fire alarm systems are essential for the safety of life, so it is important to carry out this work with confidence and competence. They are designed to warn occupants of a fire so they can safely evacuate the premises. The main advantage of installing it is the early warning benefit. When a fire system is activated, it boosts your safety and security during a destructive event.

It does save lives. But how does it work? Let’s take a look at the structure.

Active fire protection composes of smoke detectors, heat sensors, sirens, or devices that produce loud noises to warn people. These sensors are to detect certain levels of heat or smoke that could start a fire.

A loud siren sometimes accompanied by a flashlight (for people who have hearing problems). When the alarm is triggered, the sounders operate to warn people to evacuate. The system may also incorporate a remote signal system which could then alert the fire brigade through a central station.

Control panel:

It is the control center and the brain of the system. It manages and monitors the initiating devices and relays the signal if an issue is detected. When a smoke detector sends a signal, the control panel responds to it either by lighting up or making noise. Each control panel provides a display that informs you about the current status of the system.

Detectors:

These are located at the core of the system. There’s a wide array of detectors divided into groups: heat detectors (works on temperature basis, the alarm will trigger when the temperature exceeds a pre-set value). There are 3 types of smoke detectors:

1.      Ionization (contains two chambers, the first one is used to compensate for changes in temperature and the second contains radioactive source which ionizes the air)

2.      Light Scattering (it operates the Tyndall effect, i.e., a photocell and light source are separated from each other)

3.      Light obscuring (smoke interferes with a light beam between light source and photocell, and the photocell measures the light it receives).

Primary and backup power supply:

It also comes with access to two power supplies. The primary power supply is used constantly, and the backup is used in case of failure.

Alarm initiating device:

This device informs the system that there is some sort of danger. These devices can also be manual, where someone has to pull or glass station to notify the system.

Alarm notification device:

It is arguably the most important part of the system as this is the device that gets triggered by the initiating device and makes noises and notifies people.

Remote control and display panels:

It allows people to control a set of alarms even when they aren’t nearby. They are extremely beneficial for big businesses.

Building safety interface:

It allows the system to control other elements of the building when needed. For example, in case of a disastrous event, a building interface could directly communicate with the system to hold doors in the open position or keep them close to restrict the passage of smoke.

People should consider installing fire alarm systems in every workplace and even in houses to secure themselves and take the a basic fire alarm course for the essentials of their safety.

Fire alarm installation

Everyone should be aware of the fire risks within their workplace and should consider installing fire alarms. This system alerts you whether you’re busy working or sleeping, and you can take action before major damage takes place. A sound of a well-installed and maintained alarm system is the only thing that can alert you from a fire, so ensure that you install your systems properly. The type of fire alarms depends on where you are installing it.

Surface-mounted panels are always easiest and quickest to install. Avoiding excessively hot location is a great idea; it reduces battery life.

Requirements:

Initiating and supervisory devices should be of an approved type and should be installed in accordance. Construction documents should show the location and the number of all alarm initiating devices and a complete sequence of operation for the system. All devices, appliances, and equipment should be approved for the protection signaling purpose. It should be installed and maintained in all occupancies.

If manual alarm boxes (pull stations), their height should not be more than 42 inches. Each floor should be zoned separately (a detection zone should not cover more than one story), and the length of the zone should not exceed 300 feet. Audible alarm notification should be provided with a distinctive sound that is not being used for any other purpose. The system should be provided with a reliable primary and secondary power supply in case of a power outage.

There must be a clear break between to ensure alert and evacuation messages are not overheard from adjacent areas. Another criterion is that an alarm zone may consist of several detection zones but not vice versa. Therefore, it is important to see that only one message is being heard at a particular time when two zones are attached. Select the correct sensor for the application to provide the earliest warning without the risk of a false alarm. Try to visualize the type of fire most likely to occur in an area to familiarize oneself with the application and risks that could give rise to a false alarm. The most common mistake is to mount a smoke sensor adjacent to the air conditioning.

Fire alarm installation

A designated circuit breaker should be turned off on the service panel. Check circuit wires at the panel location by bringing the non-contact voltage tester near the back wire. The non-contact voltage will emit a continuous sound if there is voltage present in the wires, and it will remain silent if it is safe to work on. AC power input terminal strip and zone terminal should be located on the panel. Connect the wires to the terminal screws. To make these connections, wrap the wires around the screws in a clockwise direction and tighten them.

Alert your family and friends on the importance of installing these systems. They could act as a miracle and help you save your life.

Fire alarm system

The latest technological revolution is significantly improving the organization, or individual response for timely communication in response to fire events. A modern system can identify the presence of smoke in the most challenging environment, as it is programmed to alarm to release suppressant.  An intelligent alert is mandatory to find any suspicious change in your environment to address the problem immediately with fewer chances of damage.

The fire alarm can detect fire at an early stage, which is vital to get enough time for evacuation of occupants. Early detection is mandatory for getting a significant emergency response. Downtime can be reduced through early detection; this reduces the chances of massive asset destruction. Most of the fire systems provide quite efficient responses for sending information to emergency panels to speed up the process of fire control. 

Although safety devices are part of our offices, houses, and factories somewhat, they are mostly overlooked until an emergency surprises us. Whatever the method is, if the alarm is triggered, it can warn people before the situation gets out of control. It may have a remote signal system to convey an alert message to the fire brigade central control panel.

Most of the fire detectors are aligned with alarms; it helps to transmit an instant signal to the monitoring staff. In some situations, alarms may ring directly in the fire department, although it is not quite a common practice.    

The basic alarm is not with a detection system, and its manual system sounds like a local alarm. It is highly reliable on the occupant to indicate the fire so that it may cause a delay for action. For a more quick response, the latest system is required. Air-aspirating smoke detectors proved highly valuable with a rapid indication of danger yet a bit expensive deal.

These initiating devices work as a system that can originate from a timely signal. Manual pull stations, detectors, and supervisory devices are the main components. Pull station is positioned as a switch that operates by building occupants. Switches are typically located at the existing routes of building.

Few latest devices offer accurate peer-to-peer technology, where the network module and sensors can directly engage in the central control system. It helps to build a reliable support system for responding within seconds. The device in this system can generate complete information about the hazard's place, so it ensures an immediate action plan. Quick detection can make alarm work to issue instant alert message for the authorities to come in action.

When selecting a fire alarm must consider that for the maintenance of the quality of alarm, your efforts play a significant role. These systems require extensive testing, inspection, and support. You will have to meet these requirements throughout the life of the system, so this shouldn't cost you more than the installation expenses. Without proper maintenance and care device will not be able to coordinate with safety panels efficiently, it is necessary to keep a check on the parts, and functions to get maximum utility form system.

Types of fire alarm systems

A fire alarm system is designed to alert us to an emergency so we can take action at the right time to protect ourselves, staff, and the general public. Installing these systems is one of the prudent measures you can take to give advanced warning of a developing hazard and manage your risk. They are important because they save thousands of lives and reduce property loss.

With a wide range of these safety systems available in the market, people usually get confused about which one to invest in and which one will prove beneficial to them.

1.     Conventional: These are confined to a smaller area like restaurants and shops. They are quite affordable compared to others. They are wired in radial circuits and work by categorizing the building into different detection zones with call points, and detectors in each sector hardwired to a control panel on dedicated circuits.

Zones are just to give a rough idea of where the fire has occurred, and the accuracy of knowing where it has started is controlled by the number of zones a control panel consists of. And accordingly, the number of circuits that have been wired within the building. The control panel is connected to two sounder circuits that contain bells and electronic sounders. As the sensor is activated, the control panel helps in identifying the circuit.

 2.     Addressable: Call points and sounders are wired in a loop around the building, with each device having its unique address. They cover a large area and come with distinctive designs and complex networked systems, making them expensive. They allow a pre-alarm warning before it activates the siren. The good thing is that they can also alter the alarm threshold to meet the requirements of a certain environment. They give information about individual detectors and pinpoint the device raising the alarm. This control-system receives status reports and information and signifies its precise location if there’s a fault.

 3.     Wireless: They are flexible, pocket-friendly, and quicker to install but are also a little pricey. The main advantage is that the system can be installed temporarily and removed as required and can also be repositioned very quickly. Since there is no cabling involved, it takes very little time for its installation. As it runs on batteries, you won’t face any disruptions in the case of any power outage. In today’s world, the trend of using wireless applications is becoming very popular, where laying wires are impractical, expensive, and also time-consuming.  It has also become an integral part of the modern lifestyle.

 4.     Aspirating smoke detection system: They are highly sensitive, which can detect smoldering fires quicker than others. It uses a fan for drawing in air from across the building through sampling holes and pipes. It is pricey to install and operate. However, they are extremely useful when early warnings are needed.  They are effective as they provide the earliest possible warnings and enable a fast response to the first signs of smoke.

 Now that we’ve discussed several types of fire alarm systems, it might be easier for you to choose the one appropriate to your environment.

Fire alarm systems’ Importance

The fire protection systems have multiple parts, and the alarm system is the most critical invention throughout history as it prevents loss of lives and property damages. These systems are designed for various properties according to their requirements, and some of them have complex systems such as wiring, equipment, and other components. Its design is crucial for proper functioning so that it can work well and provide safety to all the individuals in the property in case of fire. 

The latest fire alarm systems consist of fire control panels,  alarms, and fire detection, and all of them should be implemented together to save maximum number of people and buildings. Without further information, let’s discuss the alarm design concept.

Fire alarm system design

No matter if you are not going to install a fire system still, it is essential for you to understand its design so that you can perform emergency work without hassle. The system design will help you know the structure of the control panel, troubleshooting, horns, and pull stations.

Below is the design explanation of it. Typical design is made up of the following component;

Initiation devices

This equipment can be water stream sensors, smoke sensors, heat sensors, and they can likewise be worked physically or manually like manual call points. Initiating devices are the primary segments that keep the fire alarm system in caution state. These started detectors are associated with the assistance of 2 or 4 wires. These equal wires are grounded at the control board with the assistance of connectors. Every detector has a solid state circulatory that utilizes and regulates this voltage. The voltage is likewise required for observing the situation of the control board.

 Notification appliances

These parts let the people know about the coming danger, and they can be bells, flasher lights, horns, or can be a combination of different units. These devices can work in hazardous or waterproof areas.

Control Panel

The Control panel is the brain of the alarm system and it consists of the user interface and programming codes. The LCD display also included in it, which allows users to troubleshoot troubles by using a touch-pad. Users can reset or reprogram the control panel.

Emergency batteries

12 V or 6 V batteries are included in these fire protection systems in series to provide 24 VDC. These batteries are just like the batteries that are used in emergency lights. Some of the systems have separate batteries, and some of them keep the control panel. Continuous charging is required for the batteries in case of emergency use when there is no electric supply.

Fire alarm installation recommendations

It is recommended to install the fire protection control panel near the communication point (phone or network point) so that one can make a call immediately in case of an emergency. Choose the installation area carefully; if you are going to install it in a building, then security headquarter can be a good choice as it has optimum coverage. It also should be away from the offices or kids' rooms in the daycare centers, so the firefighting team does not receive a lot of false alarms. Try to install the fire alarm components in a central location of a big building so that everyone can hear it easily.

Final words

A good fire alarm design guide is required to design an alarm system. You have to do a proper and comprehensive analysis of all components based on your knowledge as a fire alarm designer. Make sure to get one of the online eBooks in this field before installing a fire alarm system.
