FIRE MONITOR ANTIFIRE, FIXED (LS)
GOST R 51115-97, TU 4854-026-72410778-2013
General
Purpose and scope
The Antifire fixed fire monitors are intended for use as a part of foam/water fire extinguishing installations, water cooling, when fire extinguishing agents are applied over long distances or at high-rise objects, as well as when there is a need to carry out fire extinguishing at safe distances.
Reliable and stable operation of fire monitors is ensured at an ambient temperature of minus 60 °C to plus 50 °C.
Distinctive advantages
- the design is convenient to operate when placing fire monitors on fire towers of PVU type (control elements do not prevent the operator’s work on the tower platform; the control of the horizontal and vertical nozzle positions, the adjustable cone angle and flow rate, as well as the water curtain is ensured etc.);
- extended package of the basic design, depending on the application and tasks;
- optional delivery complete with fire towers of PVU type;
- material stainless steel.
Scope of supply
The basic package of Antifire fixed fire monitors contains:
- a turnable base to provide nozzle rotation around the axis of the mounting flange, as well as change the angle in the vertical plane;
- a nozzle for applying a continuous water jet (for LS-S);
- a nozzle for applying a continuous low expansion foam jet (for LS-SP);
- universal water/foam nozzle for applying a continuous or sprayed jet of water or low-expansion foam with adjustable fog cone.
Optionally, the Antifire fixed fire monitors can be equipped with:
- a pressure gauge for monitoring nozzle pressure;
- a positional flow-rate regulator with a cleaning function (this equipment is provided only for universal nozzles of the LS-SU type);
- an ejector to intake a foam concentrate from an external container (this equipment is provided only for LS-SP and LS-SU types);
- a deflector for narrowing and spraying a continuous fog cone (this equipment is provided only for nozzles of the LS-S type);
- sprinkler to form a water curtain;
- an oscillator for reversing the nozzle left / right rotation when applying water or foam concentrate solution;
- overlapping disk lock at the nozzle inlet.
Note
It is recommended to protect the fire monitor with Tauer universal fire filters (PFU) with a mesh size of 2x2 mm. The LS-SU fire monitors which are not equipped with a positional flow-rate regulator with a cleaning function, must be protected with fire filters.

Scheme and technical conditions for the use of an oscillator equipped the Antifire LS fire monitor
Specifications for oscillator application:
- when using an oscillator, it is necessary to take into account the pressure loss of 0.1 MPa, i.e., the LS upstream pressure must be increased by 0.1 MPa;
- in the LS labeling, it is necessary to indicate the value of the oscillation position (1, 2, 3 or 4).

Design Information
When determining the number of fire monitors and developing sprinkler irrigation maps with a radius of monitor’s action, the range values indicated on the graphs should be taken with a factor 0.7. Multiplying the value of the LS range obtained from the graphs by a decreasing factor, determine the effective range. This is necessary when taking into account wind loads and ensuring the application of the bulk of the extinguishing agent to the protected object. This factor also takes into account that, according to the methodology of GOST R 51115, LS ranges are determined by the extreme drops with a fair wind up to 2 m/s.
If it is necessary to evaluate the vertical application of jets by the fire monitors, the calculation and graphical method should be used with the dependency graphs of the height and range of the upper point on pressure.
