What should be taken into account during the installation of fire alarm systems and in the future
Let's start in order and describe in the text of this article the main technical procedures that accompany the process of coordinated and effective operation of fire alarm systems. These procedures include: — direct installation of fire alarms; — commissioning; — testing the functioning of the fire alarm.
Installation of fire alarm systems
After the selection and purchase of the necessary equipment has already been completed, the problem of the correct installation of fire alarm systems at the selected facility arises. We will not dwell once again on the fact that it is best to trust the implementation of this procedure to professionals. As a rule, installation of fire alarm systemsare carried out by specialists from the same company from which you purchased the equipment. It would also be useful for you to know the main stages of the installation process. So, first, a project plan is developed, which considers the number, installation locations of fire alarms, their hidden or open type, distance from heat sources or areas that threaten the integrity of the fire alarm elements. Then, the installation work itself is carried out on installation of fire alarm systems. A non-specialist will not be able to evaluate the work performed «by eye», therefore you will be able to judge the quality of the installation during the operation of the purchased equipment. Of course, it will only work well if the installation was carried out at the proper level. Of course, you would not want to wait for critical situations, especially to make sure in practice that the quality is below the declared level. Subsequent verification procedures can also reveal whether there are any defects in the installation. If the installation work is carried out by specialists of the supplier (or manufacturer), then the responsibility lies with the management of this company, and, as a rule, they do not neglect the quality of the installation work, providing services for the installation of all types of fire alarms.
Commissioning of fire alarm systems
The next stage before the final commissioning of the equipment is the commissioning of fire alarm systems. This stage is no less important than the previous one. It is necessary to carry out mandatory verification of power supply sources beforehand. In order to start commissioning, it is necessary to conduct tests on control and receiving devices and detectors. The process of conducting commissioning works of fire alarm systemsincludes work on adjusting previous readings of technical equipment adjustment. The figures obtained after adjustment work must correspond to the operational characteristics. During adjustment work, the fire alarm system is checked in the operating mode, taking into account the control of the interaction of its components. At the final stage, a comprehensive adjustment of technical means is carried out, as a result of which stable operation of the fire alarm system is achieved under specified conditions and with guaranteed parameters.
Fire alarm check
During the operation of fire alarm equipment, it is necessary to monitor the technical condition of the equipment. According to the manufacturer's instructions, the time periods are set when it is necessary to check the fire alarm. Usually, the serviceability check is carried out once a month. In this case, the corresponding measurements are made using control and measuring devices. At the first stage, a general check of the fire alarm is carried out — by provoking an alarm signal using specially created sources of light, heat, smoke, by pressing the button of the manual alarm. All obtained check data are recorded in the log of preventive and control checks. The stage of internal check of the fire alarm should be carried out once a year. In this case, the condition and quality of installation and units of devices, as well as the leakage resistance between the wires of the signal lines and the resistance value of the signal line are checked. Of course, during the check, you should also observe safety measures, using basic electrical protective equipment, since the process can be accompanied by dangerous and harmful factors for life and health: a dangerous voltage level in an electrical circuit, the short circuit of which can occur through the human body; a fall of personnel from a height when working on stepladders. Therefore, checking the fire alarm must be carried out in special clothing, the classification of personal protective equipment implies the presence of special gloves for this type of work. The power supply to the power panel must be disconnected before starting work.
