Information on organization and maintenance of installation works.

6.1. Installation of the MUPTV60 fire extinguishing module is recommended in the following sequence: preparatory work, measurements of the protected room, binding and installation of the module.

6.2. Piping shall be laid with a slope of at least 1:100 towards the sprayers.

The distance from the nozzles to the attachment unit of the corresponding pipeline is not more than 0.5 m. The distance between the pipe attachment elements must be not more than 3 m.

6.3. Install the pipelines using clamps and on site, in accordance with the placement plans, coordinating the attachment places with the site administration.

6.4. For the pipeline use steel water-gas galvanized pipes) as per GOST 326275.

6.5. Wires and cables shall be laid in accordance with PUE, NPB 8801.

The circuits of alarm loops shall be laid along the walls and ceiling in 20x10 ducts or non-combustible corrugated pipe 16, install by wire of KSPV 2x0.5 mm type.

Start-up and warning circuits shall be laid by 2x0.75 mm2 PVC wire in corrugated pipe 16. Start-up and alarm circuits can be laid together in one corrugated pipe.

6.6. In all cases where wires and cables pass through walls, wire or cable, lay in a separate piece of steel pipe.

6.7. The distance between the fire-fighting communication systems by cables and power cables shall not be less than 0.25 m.

7.electricity and grounding

7.1. AUPTRV electric receivers shall have category I power supply according to PUE in terms of power supply reliability. If it is impossible to supply electric receivers from two independent sources, it is allowed to supply them from one source: from different transformers of two-transformer or from two nearby single-transformer substations connected to different supply lines laid along different routes with an automatic reserve input device.

7.2. At objects of power supply reliability category III it is allowed to use storage batteries providing power supply of electric receivers in standby mode for 24 hours and in "Alarm" mode for at least 3 hours.

7.3. Earthing of modules tanks shall be performed by wire with copper core section not less than 1.5 mm2. Connect all grounding wires to the common grounding circuit of the building, refer to RD 78.14593. Operation of the device should be carried out in accordance with the "Rules for technical operation of electrical installations by the consumer" and "Intersectoral rules for labor protection (safety rules) during operation of electrical installations" put into effect with the 01.02.2001 of the State Energy Supervision.

Maintenance and maintenance of automatic fire extinguishing plant with fine water

At the facility, all types of work on maintenance and maintenance, as well as on the content of fire automation units, must be carried out by the facility's own specialists who have undergone appropriate training, or under an agreement with organizations licensed by the State Fire Service management bodies for the right to perform work on the installation, adjustment and maintenance of fire automation units .

The main purpose of maintenance is to carry out measures aimed at maintaining the units in a ready-for-use state: preventing faults and premature failure of component devices and elements.

The structure of maintenance and repair of modules includes the following types of works:

maintenance;

planned maintenance;

planned overhaul;

unscheduled repairs.

Observation of planned work of installation, elimination of the found defects, adjustment, control, approbation and check of integrity of chains of start of the elements gas-generating belongs to maintenance.

The scope of maintenance includes partial disassembly, replacement or repair of the module. Measurements and tests of equipment and elimination of detected defects are carried out.

The scope of overhaul, in addition to the work provided for by the current repair, includes the replacement of worn-out plant elements.

Unscheduled repairs are carried out in the scope of current or major repairs and are carried out after a fire, accident caused by unsatisfactory operation of the equipment, or to prevent it.

During maintenance works, the requirements of the "Instructions for the Organization and Performance of Works on Regulated Maintenance of Fire Fighting, Fire and Fire Alarm Plants," 1982, the Ministry of Internal Affairs of the USSR and the Ministry of Defense of the USSR, RD 78.14593, as well as RD 0090196 "Fire Automation Plants. Technical Content Rules. "

The standard maintenance schedule for MUPTV60 is provided in MUPTV60.000 RE.
