You are probably well aware of the regulations requiring your building or buildings to have a functional fire alarm system if you own, operate, or are constructing any kind of commercial property. However, many people are unaware of how these systems operate and frequently mistake them for standalone fire safety devices like smoke detectors or fire sprinklers. However, compared to a single device, fire alarm systems offer a significantly more thorough and sophisticated approach to fire prevention. Wireless fire alarm would be best for you because u wouldn’t have to deal with all the wires and stuff.
This blog post will explain the function of a fire alarm system, its main parts, and the fundamentals of how these parts cooperate to safeguard your building and its residents in the case of a fire.
A Fire Alarm System: What Is It?
A network concerning devices that cooperate to identify and notify people of a fire is called a fire alarm system. It has sounders, control panels, and sensors to aid start an emergency reaction quickly. These technologies are necessary to guarantee the early detection of even minor fires. A fire alarm detection device can reduce damage and save lives by promptly informing people.
The Essential Elements Of A Fire Detection System
The components of a traditional fire alarm system include the following:
- Panel for fire alarms
- Bases and detectors
- Points of call
- Flashers and sounders
- Accessories for the power supply (fire alarm batteries)
Between the fire management system and the other devices, wireless fire detection systems don’t require any wires. Nowadays, the majority of fire alarms are wireless. The most sophisticated ones can be combined with different software programs and make use of intelligent technologies.
Various Fire Alarm Detector Types
The detection devices are the foundation of a fire alarm system. They come in a variety of forms, from basic manually controlled break glass units to highly advanced intelligent smoke detectors. However, we may categorise them into the following groups:
- Heat sensors
- Smoke detectors
- Detectors of carbon monoxide
- Detectors with many sensors
- Manual Points of Call
Smoke Detectors
There are two types of smoke detectors: optical and ionisation. Optical smoke detectors use infrared spectrum sensors to “see” the smoke. Light scatters as smoke particles enter the sensor. The alarm is set off by this. Ionization detectors operate on a different principle: smoke particles cause the air to become less ionized, which sets off the alert.
Detectors Of Heat
The temperature of the surroundings is tracked via heat detectors. They set off the alert in the event of a very sudden rise. Certain heat sensors are pre-programmed to detect the highest temperature permitted in the space. Which of the other parameters vary the alert sounds when this threshold is surpassed?
Control Panel For Fire Alarms
It’s simpler to comprehend how fire alarms operate now that one understands what’s inside. The fire alarm control panel receives signals from the smoke and heat sensor whenever it detects an unusually high environmental temperature or smoke level, which causes that component of the ventilation system to activate and sound the alarm.
Notification
A fire detection system can notify residents and, in some situations, emergency personnel on the scene. Notification appliances that are both visible and auditory are used to deliver notifications. Strobes are usually used to offer the visible announcement, while speakers or horns—which can produce a single tone or a variety of tones and speech signals—are used to provide the audio notification. Through a notification appliances circuit (NAC), the fire alarm control unit sends the signal over to the notification appliances.
Frequent Upkeep
To ensure that they are operating properly, all security measures should undergo routine testing and inspections. Due to the rarity of fires, periodic testing is necessary to determine whether or not your alarm system is still functioning.
How Are Fires Found By Fire Alarm Systems?
The aforementioned initiating devices are how a fire detection system finds a fire.
Either two or four wire circuits connect the fire detector panel to the starting devices of the system. This circuitry enables the management console to determine if the initiating devices fall under alarm or normal operating mode by tracking their status, typically by zone. These readings are displayed on the control panel’s display.
The fire alarm system is alerted to the fire and placed in alarm mode when a fire starts, either by someone activating the manual pull station or by the smoke or heat activating one or more of the initiating devices.
After The Fire Alarm System Is Activated, What Happens Next?
Two things ought to occur when the system enters alarm mode:
- Everyone on the construction site should be alerted to the risk by the indicated equipment sounding the alarm.
- The system’s phone lines should be used to contact the monitoring provider.
- Certain fire alarm systems can turn on fire suppression systems to combat the fire until help comes.
Final Words
Fire alarms are essential, and it would be careless to install a system for access control that does not adhere to all fire safety regulations.
