8、ts the public security fire prevention surveillance department the examination and approval opinion.Second, fire auto-alarm system equipment establishmentFire detector establishmentOpens wide either the seal or the stair hall should alone divide the search coverage, and each 2 3 establish a fire det

9、ector.The first room (including guards against in front of smoke stair hall in front of room, fire elevator room, fire elevator with guards against the front room which smoke stair hall comes in handy) and the aisle should distinguish alone to divide the search coverage, specially front the room and

10、 the lift well, the scattered stair hall and the aisle are interlinked, has time the fire haze to be easier to gather or to flow, is the personnel disperses which saves goal with the fire prevention, therefore should install the fire detector. Regarding common elevator in front of room although is n

11、ot the personnel disperses , but this front room and the lift well are interlinked, has time the fire haze to be also easy to gather or to flow, suitably alone divides the search coverage and installs the fire detector.The electric cable shaft therefore is easy to form pulls out the smoke inflammati

12、on the channel; Has when the fire the fire intensity not easily extends along the electric cable burns, for this, "the high level civil construction design fire protection standard" and "the civil construction electricity design standard" separately proposes the detailed specific

13、 stipulation in the construction and in the electric wire or on the electric cable shaping. But considered implements specifically the difficulty and the present situation, the electric cable shaft installs the fire detector is extremely essential, and coordinates the shaft the fire protection separ

14、ation request, each 2 3 or each level installs.The elevator machine room should install the fire detector, its elevator is the important vertical transportation vehicle; Its two elevator machine room has has the fire risk; Its three lift well existence essential opens the hole, like the level gate o

15、pens between the hole, the air vent, the between permanence opens the hole with the elevator machine room or the pulley and so on; Its four when has the fire, the lift well often becomes the fire intensity spread the channel, is easy to threaten the elevator machine room the facility. Therefore, the

16、 elevator machine room establishes the fire detector is necessary, crown of also suitable establishment fire detector lift well.2nd, the manual fire reports to the police the button establishment(Including guards against in front of smoke stair hall in view of various floors front room in front of r

17、oom, fire elevator room, fire elevator with guards against which smoke stair hall to come in handy the front room) is has when the fire the personnel to disperse which saves goal with fire prevention, should report to the police the button first choice spot as the establishment manual fire. In addit

18、ion, the room also should establish the manual fire to the common elevator in front of to report to the police the button.In the public active place (including hall, hall, dining room, multi-purpose hall and so on) and the main thoroughfare and so on place, the personnel very is all centralized, and

19、 mainly disperses the channel. Therefore should report to the police the button in these public active places main access establishment manual fires; The manual fire establishes which in the main thoroughfare reports to the police the button to guarantee "to a manual fire which most is close to

20、 reports to the police the button distance from a fire protection district any position not to be supposed to be bigger than 30 meters".3rd, the fire emergency broadcasts the speaker the establishmentThe aisle, the hall, the dining room and so on the public place personnel very are all centrali

21、zed, and mainly disperses the channel. Therefore should press in these public places "to a recent speaker distance is not bigger than 25 meters from a fire protection district any spot" and "in the aisle last should not be bigger than 12.5 meters the speaker to the aisle terminal dist

22、ance" the establishment fire emergency to broadcast the speaker; Next also should establish the fire in the public bathroom place emergency to broadcast the speaker.The first room (including guards against in front of smoke stair hall in front of room, fire elevator room, fire elevator with gua

23、rds against which smoke stair hall to come in handy the front room) is has when the fire the personnel to disperse which saves goal with fire prevention, also has the fire door separation and the sounds of people is confused and noisy, therefore should establish the fire emergency to broadcast the s

24、peaker. In front of the common elevator the room also should establish the fire emergency to broadcast the speaker. Disperses the stair hall also is has when the fire the personnel to disperse which saves goal with the fire prevention, also the sounds of people are confused and noisy, therefore shou

25、ld establish the fire emergency to broadcast the speaker, by favors the fire emergency broadcast to disperse the instruction.4th, fire alarm installment establishmentThe establishment fire emergency broadcast fire auto-alarm system, the author thought also should install the fire alarm installment,

26、but its control procedure should be: The alarm apparatus should confirm after the fire, uses manual or the automatic control mode unification to the fire correlation region transmission warning, stops the alarm apparatus work in the stipulation time, the rapid linkage fire emergency broadcast and br

27、oadcasts to the people disperses the instruction.The fire alarm installment establishment position, the author thought should report to the police the button position with the manual fire to be same, its wall surface installment should for be apart from the ground 1.8 meters highly5th, fire special

28、use telephone establishmentInstalls the fire special use telephone extension telephone, should be located the engine room which related also some people is on duty frequently with the fire linkage control (including fire water plant, spare electricity generation engine room, matches substation, main

29、ly ventilates with air conditioning engine room, discharges fume engine room, fire prevention elevator machine room and other), the fire fighting control system operates the equipment place or the control room, the fire duty officers observation room, the security manages spot and so on public room.

30、 Sedan of theater box the fire elevator and in the ordinary elevator all should suppose the special use telephone, requests the elevator machine room and the elevator sedan theater box, the elevator machine room and the fire control room, the elevator sedan theater box and the fire control room and

31、so on three compositions is reliable to speaks the correspondence telephone system. Usually in fire control room; The establishment elevator monitoring demonstration plate (including position indicator, direction indicating lamp, to speaks correspondence telephone, trouble lamp and so on), in order

32、to carries on the necessity to the elevator running status which in the surveillance and the emergency case controls.Is equipped with the manual fire to report to the police position and so on button, fire hydrant button also should install the fire special use telephone receptacle.Third, fire linka

33、ge control1st, the fire linkage control should include the control fire pump to open, to stop, also should demonstrate opens pumps the button the position and the fire pump work and the malfunction. When the fire hydrant is equipped with the fire hydrant button, its electric installation work spot a

34、lso should demonstrate the fire pump the working mode active status (namely establishment fire pump work indicating lamp).2nd, the fire linkage control should include the control spraying of water and the water atomization fire fighting system opens, stops, also should demonstrate the fire pump the

35、work and the malfunction and the fluent display, reports to the police the valve, the safety signal valve working mode active status. In addition, to the basin, the water tank water level also should carry on the demonstration monitor; In order to prevent the overhaul signal valve is shut down, the

36、author thought should use the belt electric signal the control signal valve by to demonstrate it opens the condition.3rd, the fire linkage control other controls and the demonstration function, should carry out the present national related standard and the standard specific stipulation.Fourth, fire auto-alarm system wiringIn order to prevent the fire occurs when the fire control, the correspondence and the warning line severance, causes the fire fighting work to be unable to carry on, creates the
