4.5.2.3 detector installation location, the protection of RADIUS, area requirements.

4.5.3 allowable deviation:

4.5.3.1 detector away from walls, Liang Bian 0.5M and around the curtain from air conditioning air outlet distance ≥ l.5M, porous fence ≥ 0.5M.

4.5.3.2 width less than 3M set the detector to the occasion on the top center of the aisle layout, temperature detector installation distance 10m, 15m smoke detector installed, should be greater than the distance from the detector from the end wall of the detector installed half the distance.

4.5.3.3 detectors should be installed horizontally if it is necessary to tilt when installing its tilt angle not greater than 45 °.

4.6 the section contents of quality assessment, if it is a subcontractor, contractors quality assessment quality assessment for these items should be added to the common assessment in the building Division of electrical installation engineering. If works, quality assessment for these items as a unit of electrical installation (Division) project, according to the relevant requirements of GBJ300-88 assessed quality rating.

5 finished product protection

5.1 when steel pipes laid in concrete or a wall, sealing tube and box in a timely manner, so as not to enter the debris under the influence of process threads, causing tick chisel; civil engineering concrete or masonry to a hand tie, avoid laying pipe displacement resulting in rework.

5.2 pipe thread: Groove when wiring within the remainder of the wire should be placed in a box or boxes, covers and slot cover in a timely manner to avoid wire damage or loss.

5.3 automatic fire alarm system equipment store, to dust, moisture, anti collision, smashing prevention, prevention measures such as safekeeping and handling procedures for incoming inspection and permit.

5.4 automatic alarm device installation, civil works should meet the floors, walls, Windows and doors, spray finished in dedicated under the condition of the installation.

5.5 after the completion of fire control room and a room equipped with a controller should be locked in time, close the doors and Windows, the equipment should be covered with dust and moisture Department.

5.6 alarm detector should be mounted on the base, and wear a dust cover reloaded when you debug probe.

5.7 after the completion of terminal box and module boxes to door locks, box cover to protect the body from being polluted.

5.8 loss of damaged equipment such as manual alarm, Horn, phones and phone jacks should be installed last, protection measures are required.

5.9 installing alarm systems and equipment, civil works and decorative work have come to an end, installation steps should be taken to ensure that the walls, floors, ceiling from damage and pollution.

5.10 when pick slot, picking holes in the construction, not breaking structural reinforcement in, must be broken, and shall be subject to approval of the construction and design can be broken, especially its main steel structure must be in strict compliance with the provisions of this article, otherwise it will cause irreparable accidents.

6 quality problems to be noticed

6.1 construction workers should strictly abide by the 6-l "General requirements for the installation of fire engineering and related provisions", which is an important condition to ensure project quality and service.

6.2 strengthened into the factory inspection of equipment and materials, its quality must conform to the requirements of the relevant specification and the process, cannot use the nonconforming product.

6.3 quality problems should be paid attention to in construction:

6.3.1 simmer bend found concave flat too large or sufficient bend RADIUS multiple phenomena, the solution is the use of hand and simmering bending moves to moderate, not too hard, until you meet the requirements.

6.3.2 embedded box, boxes, brackets, hangers, skew, or box with too many people coming in and going out is too serious, according to resize or re-planted.

6.3.3 out piping or piping in the ceiling, unstable fixed point, iron clamp loose and fixed point are too large and uneven, should be the supporting pipe clamp fixation, span should get even.

6.3.4 dark match pipe plug, piping should be added in a timely manner after jammed tight shutoff nozzle, and you should always check, found leakage blocking or dropped in time blocked, such tubes have been blocked to handle repairs.

6.3.5 prohibited the use of electric weld and cut the pipe. Bracket and the holes in the box set, and saws and reamers should be used for the construction, flush cut requirements, with a file to remove burrs and then piping.

6.3.6 cartons, boxes, destruction of galvanized steel pipe, galvanized layer should be promptly treated.

6.3.7 using metal hose should not be longer than the 2m, fixed spacing should not exceed 0.5M, fixed at both ends should be solid.

6.3.8 conductors shall be conducted according to technical specifications and color selection and installation, detector "+" line to red "-" blue line and the remaining lines according to different uses other color, but use the same wire colors should be consistent in the same project.

6.3.9 must wear protection when threading pipe to protect the insulation of the wire.

6.3.10 wire crimping the connector, rinsed Tin, bandaging, shall be consistent with this process and related regulatory requirements.

6.3.11, relative to the insulation resistance of the wires should be not less than 20M. Shaking when measuring the insulation resistance not shake test with automatic fire alarm equipment.

6.3.12 detector installation location and type shall conform to the design and technical specifications, installation location the principles established at the outset to ensure the function, followed by the appearance, such as interference with other types of equipment installed, should inform the design and consultation unit address.
