Fire alarm: maintenance and repair. Maintenance of security and fire alarm systems

Organization of security and fire systems is not without the inclusion of modern alarm. This is an obligatory component of the protective complex, which helps prevent or at least minimize the spread of fire. The effectiveness of such systems is primarily determined by the quality of design and installation. However, in the process of operation, a significant role is played by the maintenance of fire alarm systems, thanks to which its function is preserved.

Organization of maintenance

Usually the contract is concluded with the organization, which was engaged in the design and installation of the complex. In this case, the contract can be concluded immediately after the completion of installation work. The main thing is to correctly calculate the schedule for maintenance of the fire alarm system, since frequent operations are unprofitable financially, and too rare will not prevent possible breakdowns.

Usually, before a scheduled site visit, a representative of the service company details the time and the general format of the work. The fact is that checking equipment, and even more, repair work may require the suspension of the enterprise, so each time should specify the time. Further, the fire alarm, the maintenance of which was completed, is tested by qualified representatives of the customer or by experts of a third-party company. Also, the customer receives an act in his hands, in which the entire list of works was indicated and information on the current state of the equipment was given.

Checking and maintaining the control panel

The control panel is a complex inside the system, which is responsible for further actions after detecting the signs of a fire. In particular, this sends a signal to the services that are directly engaged in firefighting. In turn, from the maintenance personnel it is required to check the electrical infrastructure of the panel, assess the reliability of the connections, test the function of the equipment and, if necessary, perform the modernization. By the way, maintenance of fire alarms in the part of the receiving and monitoring console, more often than other components, provides for the equipment update. For example, not so long ago many organizations within the framework of maintenance activities began to transfer complexes from ordinary wire communication to wireless alarm channels.

Check and maintenance of fire detectors

The function of the detectors is most responsible, since these sensors reveal signs of smoke spreading in the early stages. From the specialists it is required to check the technical condition of the sensors themselves, to evaluate and, if necessary, to adjust the sensitivity settings, etc. Again, special attention is devoted to the connection nodes if a conventional wire fire alarm is checked. The maintenance of wireless systems, although it does not assume an analysis of the performance of the cable infrastructure, but has its own nuances. In particular, for the operation of fully wireless detectors, alternative power supply is required. To ensure this task, maintenance personnel must regularly change feeding elements or locally replenish energy through autonomous sources.

Testing the power status

To test the quality of wiring work, special testers are used. These are measuring devices, by means of which the voltage, current strength and other parameters are checked, on which the quality of the same detectors depends. Usually maintenance of the fire alarm in this part involves the detection of damage to the lines, but there may be other types of work. For example, in order to optimize, installers can revise the network configuration. If this task is successfully completed, you can reduce power consumption and improve the reliability of the wiring.

Maintenance of automatic fire alarm systems

Automation in fire protection systems is not as common as in the case of conventional security systems. This is due to the specific operation of the equipment in detecting the flame. This does not mean that automatic systems are completely excluded. For example, the models of annunciators in which the function of sending signals are programmed are common. Thus, an autonomous fire alarm is organized in some way. Maintenance of such systems, for the most part, provides for correct setting of the operating parameters. So, from the master it is required to bring in the correct contacts to send a signal. In addition, the parameters of functioning at different times of the day are set.

By the way, receiving and control systems assume the greatest degree of automation. If the security and fire alarm services in terms of the quality of the wiring work involves an assessment of the physical state of the infrastructure components, in this case, the main focus is on the analysis of the underlying data on which the panel is built.

Repair work and troubleshooting

It is necessary to distinguish the maintenance of systems and the immediate restoration of their technical condition. The second part is based on the data that was obtained during the initial examination. Depending on the complexity of the repair can be performed and during the same inspection, and with further maintenance. At a professional level, when working with a large facility, specialists develop design solutions that restore fire alarms. Maintenance and repair are carried out on the basis of the prepared technical solutions. For example, engineers select new components for wiring nodes, give recommendations for the installation of control equipment for the receiver and control unit, etc. Physical repair can include performing operations with electromechanical stuffing, cable connections, mechanical group elements.

How much does maintenance of security and fire alarm?

A number of factors affect the specific figures for the cost of maintenance of fire safety systems, but it should be understood that in almost every case it is a question of responsible and high-tech equipment, therefore, the prices are rather big. Accordingly, the more complex the infrastructure, the higher the qualification of masters is required - and the tariffs will be similar. On average, for 3-4 thousand rubles. In a month there is a typical fire alarm. The service in this case will have the character of staff and provide for a standard set of actions. The increase or decrease in rates may depend on the area of the object. If work is carried out at an enterprise with an area of about 150 m ² , then the cost may be 10 thousand.

Preventive works

Such measures are of the nature of preventive measures. The task of specialists in this part is to create conditions that are aimed at maintaining the equipment in an efficient state. In particular, preventive maintenance of fire alarm systems provides for the cleaning of the external surfaces of equipment, panels and wiring, assessment of the quality of installation, grinding, soldering, lubrication, and, if possible and if necessary, replacement or repair of items that have become unusable. Practice shows that prevention of this kind allows not only to identify, but also prevent widespread breakdowns of components of the fire-fighting complex. With regular inspection of signaling devices, it is possible to detect premature failure of electrical fittings, and possible violations in the operation of feeding autonomous units.
