The first room (including guards against in front of smoke stair hall in front of room, 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, also has the fire door separation and the sounds of people is confused and noisy, therefore should establish the fire emergency to broadcast the speaker. 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 should establish the fire emergency to broadcast the speaker, by favors the fire emergency broadcast to disperse the instruction.
4th, fire alarm installment establishment
The establishment fire emergency broadcast fire auto-alarm system, the author thought also should install the fire alarm installment, 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 broadcasts 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 highly 5th, fire special use telephone establishment
Installs 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, mainly 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. 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 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 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 linkage control
1st, 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 also 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 work and the malfunction and the fluent display, reports to the police the valve, the safety signal valve working mode active status.
