FAQ

No, filters are already installed in the water-mist sprinklers, and the installation of additional filters on the fire extinguishing system is not required.

Currently, water-mist sprinklers are used in hidden structures. When they are installed in accordance with the requirements of the organization standard in mounting devices manufactured by the Hephaestus company, the spray zone does not change and corresponds to the technical characteristics of the sprayers used.

Conventional fire control systems specialize in servicing single fire extinguishing areas. In rare cases, the formation of two or three dozen zones is required. The Olimp system can provide servicing of several thousand freely programmable extinguishing zones.

The number of controlled sprinklers that provide protection for large objects can be up to several thousand. Accordingly, the monitoring and control system must provide up to several thousand extinguishing zones with dynamically formed groups of sprinklers. To implement this function, the Olymp system was developed. At the lower level, fire extinguishing zones are formed by software and hardware by the local controller KL-240. It has a limitation on the formation of the number of fire extinguishing zones -240, the number of simultaneously activated sprinklers in automatic mode -12. At the upper level, fire extinguishing zones are formed and controlled by the BKU-3200 control and management unit, while the number of independent fire extinguishing zones is 3200, and the number of sprinklers switched on in automatic mode (simultaneously or sequentially) can reach 144 units.

We have worked out and proposed the implementation of group start-up of controlled sprinklers on the Bolid system (S2000 and KPB). But at the same time, additional hardware reliability must be provided, in connection with which we recommend using some devices from the Gefest PPU set. Other design solutions with the use of modern control devices are also possible, but in any case, we insist on coordinating circuitry solutions with our specialists.

The design of the heater is designed in such a way that the operation of the sprinkler in normal operation is not disturbed. It should be borne in mind that the heating element partially shields the flask, which entails an increase in the response time. To compensate for this disadvantage, controlled sprinklers are produced only with quick-response flasks. The design of the heater and related elements is constantly being improved. Real inertia and its compliance with national standards is confirmed by the results of certification tests.

A conventional sprinkler has a high inertia, heats up slowly and works, as a rule, only with a significant fire source. The higher it is set, the less effective it is. At altitudes, for example, 12 m and above, the sprinkler can be triggered when the fire source has already exceeded the sprinkler's irrigation zone. At high altitudes - 20 m and above, the sprinkler may not be triggered even after the fire load has completely burned out.

The controlled sprinkler eliminates these disadvantages, while maintaining the main function of the sprinkler as a successful fire extinguishing agent that has been used for more than 100 years. A controlled sprinkler, taking into account the high level of development of monitoring and control systems, successfully combines both a function of a dynamically formed deluge section (it can turn on in one gulp in the event of a rapid fire development, provides the formation of water curtains and irrigation zones for glasses, doors, structures), and successfully can work targeted at the detected target. Combined use of controlled sprinklers with flame detectors, television systems, etc. allow you to "soak" the arsonist at any point in the protected space, until the moment of arson. The advantages of controlled sprinklers in our country have not been fully appreciated, but European countries and America are showing a keen interest in this product.

When using UK-D 01,02,03,04,05 as part of UKLSiP (B) or UKLSiP (RP), the contacts U _pt UKLSiP (B) or UKLSiP (RP) must be supplied from 21V to 28V. It should be borne in mind that consumers on UK-D 04.05 should be with a rated power supply from 21V to 28V.

UK-D (04) is powered by the communication line UKLSiP (B) or (RP) with a voltage of only 24 V.

In this case, it is assumed that 24 V power consumers are also included in the UK-D (04) load.

If, due to a misunderstanding, plates with a supply voltage of 12 V are installed in the load line UK-D (04), the situation can be corrected due to the sequential inclusion of the ballast element (BE) from the set of PPU "Gefest". Ballast elements providing power coordination are selected individually for specific parameters of light annunciators.

At the request of clauses 5.2.1.7., 5.2.1.8 GOST R 53325 Modern power supplies should have automatic self-healing short circuit protection, and a short circuit in the power supply circuit of the warning systems should not affect the operation of the system. Nevertheless, in practice, at least two unpleasant situations are possible:

1.) The power supply is not electronically protected, but a fuse.

In this case, a short circuit in the power supply circuit of the warning systems causes a short-circuit impulse current (up to 80A) to flow and the fuse in the power supply burns out. As a result of the check, the warning system and everything that was connected to this power supply unit is turned off indefinitely.

2.) The power supply is protected by an electronic fuse, but provides power to both the warning systems and the alarm control panel.

In this case, a short circuit in the power supply circuit of the warning systems triggers the electronic protection of the power supply, the voltage in the line is removed for the duration of the short circuit, but at the same time the control panel is turned off, which was supposed to fix a malfunction in the system.

Any of the situations may not please the inspector (inspector), which will entail trouble, including the financial plan.

To exclude such situations, it is advisable to use a short circuit insulator for power circuits (ICZ CPU). It allows you to divide the power supply output into two independent circuits, one of which provides power to the control panel, the second directly to the warning system. ICZ CPU for each channel provides instantaneous electronic short circuit protection. In the event of a short circuit in the warning power circuit, even the fuse does not have time to "burn out", while the emergency direction is cut off by an independent channel of the ICZ CPU, the second independent direction ensures uninterrupted operation of the control panel at this time.

Federal Law No. 123-FZ requires the provision of fire warning systems (and some other systems for the time required for the complete evacuation of people. Usually this time is within 8-15 minutes. In this case, the local effect of temperature on the warning system can reach 800 degrees Celsius 5 minutes after the outbreak of the fire. However, the fire resistance of the system and the possibility of its functioning during a fire is determined by the weakest link. In the case of using a fire-resistant cable and fire-resistant switch boxes, the weak link remains a light indicator, siren or loudspeaker, which will begin to collapse at temperature 150 degrees Celsius and above.If there can be no people in the room where the fire source is actively developing, then there may still be people in adjacent rooms for whom continuous notification is provided. all premises for this direction avia. People will not only stop the evacuation process, but perhaps some will return.

To exclude such a situation, it is necessary to cut off sirens located in a room with an emergency high temperature (it is problematic and unreasonable to make sirens resistant to temperatures of 400-800 degrees). The function of such a cut-off is performed by a short-circuit insulator with a thermal release, which is connected in series to the siren circuit and is located in the immediate vicinity or inside the siren. In its normal state, this product has practically zero internal resistance and does not affect the performance of the sirens and the entire system. When the temperature rises to 145 degrees (or other on request), the thermal protection is removed, and the product begins to function as a fuse. In the event of a short circuit, the emergency section is turned off, but at the same time the survivability of the warning system as a whole is ensured. The design feature of the product lies in the fact that at a temperature of 800 degrees and above, it retains the function of a short-circuit insulator.

To control the shunt release (ventilation blocking starter), it is advisable to use an independent device UKLSiP (S), which is part of the PPU "Gefest". Serially, this device is produced to monitor the cable line, the serviceability of the input electrical circuit of the control object and control the loads of the 220V network (but at the request of the customer, a product can be manufactured for a different voltage: AC 36V, 110V or DC 24V). By moving the jumper inside the device, the mode of enabling or disabling the blocking by fire signal is selected.

UK-D (02) is a smart relay that in its basic version controls the presence of a voltage of 220 V, which provides control of the communication line and the presence of a load in the 220 V circuit. The load is switched on by the "Start" command by closing the contact of the internal executive relay with a load capacity of up to 220V.

If it is necessary to control and manage three different loads in different places, then three UK-D (02) devices should be used. If all three consumers (more precisely, their starters) are in the same cabinet, and in total they consume no more than 3A in the on state (short-term impulse current, the moment of switching on can reach 40A for a time of no more than 10 ms), then they can be connected in parallel. The reliability of their connection must be guaranteed by the quality of manufacture of the control cabinet.

PPU "Gefest" belongs to the class of multicomponent devices and has the ability to build up the structure practically without limiting the number of connected sirens or other executive devices. It is necessary to take into account the energy capabilities per device, an independent communication line with control objects. So, for example, UKLSiP (B) or UKLSiP (RP) allows a load in the communication line in standby mode up to 0.5 A (500 mA) and in “Fire” mode up to 2A (2000mA). This means that, per device, 25 “Output” light sounders with a current consumption of 20 mA each can be switched on simultaneously, and in the “Fire” mode another 30 sounders (sirens) with a current consumption of 50 mA each.

It should be borne in mind that the communication line provides the ability to connect additional local branches with the “Exit” signs through the UK-D (04) device or sirens and signs activated by the “Fire” signal through the UK-D (05) device. The load capacity of serial UK-D (04) and UK-D (05) is limited to a current of 100 mA (supply voltage 24 V). However, by special order, reinforced versions of UK-D (04) with a load current of up to 300 mA and UK-D (05) with a load current of 1A (1000mA) are manufactured.

If it is necessary to increase the number of connected objects, one or more UKLSiP (RP) devices are additionally installed, acting as an expander, and the number of connected objects is increased to the required value.

There are other ways to increase the number of monitored communication lines and switched on sirens, including those powered by the 220V circuit.
