Buck 4 is connected to the transponder. Fire damper control unit
This device is a control device for fire dampers KOM-1, KLOP-1, KDM-2, which can operate both in the configured automatic mode and in the manual mode. BUOK-4 SVT1163.42.210, can control from one to four valves at once. As part of the smoke protection system and the ventilation system, this device directly controls the correct operation of the actuators of all valves, the position of the damper damper itself and the power supply control. BUOK-4 SWIT is produced in several versions, the required modification is selected according to the supply voltage and the type of connected drives.
The presented block is made of a metal case, with a working front panel, on which there are LED indicators that control the readiness of valves and dampers for subsequent operation, relays and fuses.
An alarm is installed on BUOK-4 SVT1163.42.210, it helps to timely determine the malfunction and state of the dampers of any of the valves. Fire-retardant and smoke-removing dampers with the same actuators can be connected to the device at the same time. The valves are started both in remote mode and in local mode, by pressing a button on the instrument panel. The existing terminals of the SVIT unit are connected to the damper sensors, control signals from the APS, the unit power cables and the valve electric drives.
The installation of the unit is carried out according to the corresponding plan for placing the equipment, on the walls of the room in a horizontal position. The manufacturer's warranty service is two years from the start of the unit's commissioning.
In connection with the transition to a new elementary base, BUOK-4 has been finalized taking into account the requirements of the NPB.
From March 10, only the new BUOK-4 will be manufactured
Difference between new and old BUOK-4
The new BUOK-4 additionally provides:
- control of the position and direction of movement of the flap of each valve;
- control of the integrity of the control circuits of each valve;
- control of supply voltage presence;
- formation of duplicate control teams to create one control group with other BUOK;
- control of valves in automatic mode, both by two separate control commands, and by one generalized control command;
- control of valves in automatic mode by receiving duplicate control commands from another BUOK.
The buttons of the new modification are used to control the BUOK-4.
The design of the case has been improved, which now allows BUOK-4 to be installed on the wall both vertically and horizontally, which greatly facilitates cable routing during installation.

- with electromagnetic;
- with reversible drive;
- with an electromechanical drive;
- So, the device
- from Sweet is responsible for the following functions of the fire dampers:
- are able to control the valve using the buttons on the device body in manual mode;
- are able to monitor the operation of the valves automatically, thanks to the commands received from the fire alarm devices;
- control the position of the valve flap;
- create light alerts that demonstrate the current state of the fire damper;
- provide round-the-clock control over the work of fire-retardant partings;
- can generate duplicate notifications using a relay if the valve is triggered;
Has 2 modes of operation:
- "Norm" - is the standby mode;
- "Start" - the mode of direct active functioning of the unit;
BUOK-4 SVT1163.42.210. Description of control units
Block BUOK-4 SVT1163.42.210 is a device that controls fire and smoke dampers in the ventilation and smoke control systems.
Types of clans. A group of up to 4 pieces of fire and / or smoke dampers. At the same time, valves of different types can be connected to the device at the same time.
Appointment. For operation with valves controlled by electromagnetic drives, rated for 24V Usup. The shutter is brought into the operating position manually.
Control. Manual - from the button on the front panel of the unit. Automatic (fire alarm command or from the ventilation system control panel). It is possible to issue one general Start-Stop command or separately for each command. Also, the unit can be controlled automatically from another BUOK-4 unit if an emergency occurred in the same unit, but away from this device.
Monitoring the status of a group of valves. Indirect - if the Start command has not been given, a 10-second delay in turning on the initial position limit switch will cause the Fault LED on the unit panel to light up.
Signaling of the state of objects controlled by BUOK-4 SVT1163.42.210. The panel of the device is equipped with LED signaling, reflecting the state of each valve, fuses, as well as the readiness of the dampers for operation.
Functions of the BUOK-4 SVT1163.42.210 block
- are in control:
- damper conditions;
- integrity of valve control circuits;
- creation of light alerts;
- supply voltage.

The BUOK-1 SVT667.13-111 block is an automated device required to control the power supply of the electric drive of the fire dampers. In standby mode, the circuit of the BUOK-1 SVT667.13.111 unit is closed. When a special button is pressed or a signal is received about an unexpected fire, the circuit is opened, which activates the fire dampers. The blocks of the type BUOK-1 SVT667.13-111 manufactured by SVIT allow to minimize the chance of an unforeseen fire in production, regardless of what caused the incident. The device itself is reliably protected by a metal case that can withstand high loads and mechanical damage. On the front panel of the body there are three indicators that clearly demonstrate the state of the control unit: "standby mode", "valve is actively working", "control mode". On the upper side of the case there is a red button, pressing which brings the BUOK-1 control unit out of standby mode. Due to its design, the fire damper control unit can be attached to one of the walls or any other vertical surface. Finally, in order for the control unit developed by SVIT to work smoothly, it is necessary to provide the device with 24V DC. BUOK-1 SVT667.13-112. Description of control unitsThe device for a reversible drive is suitable for controlling a single-phase valve drive by commands that are sent to the unit by a control voltage or a button installed on the unit body. Operation is carried out according to a three-pass connection scheme. It can be controlled in manual or automatic mode. The fire alarm system device has found its application at the main facilities of the country, since it has the following features: AC supply voltage - 24V, command signal - 24V. Lightweight plastic housing 105x85x70, weighing 0.2 kg consists of switches, printed circuit board, indicator lights and fuse. The model has the following operating modes: "Standby mode", "Control" and "Valve triggered". Indicator lights monitor the progress of the work and confirm this by burning with different colors. The unit must be installed according to the instructions in the housing of its electrical cabinet on a DIN rail. Installation of BUOK-1 SVT667.13-112 is carried out according to the corresponding project indicated in the passport of the device. The design of the SVIT brand device meets the fire safety requirements and is certified. BUOK-4 SVT1163.43.210. Description of control unitsThe main purpose of BUOK-4 SVT1163.43.210 SVIT is to control a group (up to 4 pieces) of fire dampers, due to which the consumer can also monitor the position of the damper of each valve, monitor the serviceability of external drives and even check the presence of much needed for the correct functioning of this appliance, power supply. In order to control such a device, the consumer must press the "Open" and "Close" buttons on the front side of this device or perform such a process by supplying a control voltage of 24V DC. The main functional features of the BUOK-4 SVT1163.43.210 SVIT control unit include the following: The magnitude of the voltage that is present at the valve actuator is 220V AC. In addition to the light indication, practically for the entire group of controlled valves present on BUOK-4 SVT1163.43.210 SVIT automatically generates the signals "Valves closed", "Valves open", and of course "Malfunction". You can switch between each of the above modes by using the corresponding contact groups.
