Fire and security alarms were created for the safety of people and things. But just buying them is clearly not enough. It is also necessary to mount a fire alarm. Therefore, within the framework of the article, attention will be paid to both general issues and specific aspects and nuances.
What is a security and fire alarm?
The installation of these systems is complicated, and before you begin to work, you need to understand what you have to deal with. So, they are a complex of technical means that are used to detect fire in a timely manner, as well as unauthorized entry into the protected area. In the case of fixing problems, a signal is sent to the control room to send a rapid response squad and mechanical means of influence are activated (if to speak of a fire alarm, the automatic fire extinguishing system is started).
Categories
We know what security and fire alarms are. The installation of this security complex can be carried out in three approaches, which depend on the categories of equipment:
- Designed for centralized management. By this is meant the presence of a computer with special software that manages all the technical details.
- Equipment designed to collect and process information that comes from sensors. These include the reception and control panels of security and fire safety.
- Directly the sensors themselves, which record violations of activity, as well as notifying devices (for example, loudspeakers).
Installation of fire alarm systems is different from security systems usually arrangement of sensors. So, for the security of the premises, it is necessary to keep the windows under control, to see if someone is moving in the wrong time, and to carry out many other operations. Whereas to track fires, it is enough to simply place the sensors on the ceiling, to withstand a certain distance, in order to effectively cover the entire area.
Integration
Their connection is carried out at the level of centralized management and monitoring of the system. They are administered by independent units or posts. Thus, their autonomy is preserved. If a small object is controlled, all the necessary tracking functions can be performed in an automated mode. An invaluable benefit in such cases is the reception and control panels. They allow you to receive alerts, generate problem reports, and send them to a central monitoring station. Depending on the complexity of the integrated system used, other components of the automated complex can also be notified of the problems. And if the installation of automatic fire alarm is something more or less real, then with security is not so easy.
Problems with implementation
Let's imagine that there is a fire at the site. We learn about him. It is relatively easy and cheap to place on it an automatic fire extinguishing system. For this, only tanks with a fire extinguishing compound are required, and a method of supply to any place. But with security everything is much more complicated. So, let's say that someone penetrated the object (or, to be more exact, the research laboratory). About the presence of someone an outsider will be notified protection, a rapid reaction team will leave, but while they arrive at the scene, it turns out that there is no one there. A unique solution can be seen in the most advanced places in the world: treasuries of countries and mints. So, if there was an unauthorized penetration and a security system was cracked, it is stipulated that a passive protection system is activated, which closes all possible outputs once more. But it is expensive and difficult to implement, so you do not have to expect that something like this can be seen a lot. And now let's find out what is necessary to make a quality installation of the security and fire alarm system.
Implementation
So that we have a high-quality security and fire alarm, installation and maintenance should be carried out by professional technical specialists. If there is a plan to take care of the house on its own (or even about a shed), then it is necessary to carefully study all the information that can only be obtained. It is also necessary to draw up a project plan, which will be implemented taking into account the normative documents that are in effect now, and also to coordinate the installation with the permitting state bodies (this refers to professional service in the first place). For installation, it will be best to use certified equipment, since homemade products can carry a certain danger if they were created by an inexperienced person. And at the very end it will be necessary to carry out commissioning works, correct all inaccuracies, solve problems and make technical documentation. In the future, only maintenance of mechanisms and maintenance of their efficiency will be necessary. To maintain the operation is very desirable to the same person (or company) who conducted the adjustment. It must be technically literate.
Sensors
We know what security and fire alarms are, how to install, install and support its work, and who should support their operation. Sensors, as well as connecting wires are key components of the system, which determine the reliability of its operation as a whole. At the same time they are laid in such a way that they are not conspicuous. For confidence use cables with at least two cores. As the sensors used there is a considerable choice. You can stay on the old good reed switches. Although if we talk about the kitchen, then we need elements that can react not only to heat, but also to smoke. Near the location of the storage of values, it is very desirable to place motion sensors. Fortunately, the cheapest options are only a few hundred rubles, so if you want you can make the whole house. Also, in order to have an idea of whether they work or not, you can select devices equipped with a signal diode. In the event of a failure, they immediately report problems.
Conclusion
If you decide to do everything yourself, take into account government regulations. They contain provisions that, on first examination, may seem too soft, but this is a deceptive impression. Thus, they provide an option for using the room by smokers with the possibility of a false alarm, as well as technical recommendations on the placement of elements of the system. And in general there is a number of useful information that will be useful to those people who do not have good experience in this field.
