Introduction
0:1 According to the classification of GB/T 15706, this document belongs to the category C standard:
This document is particularly relevant to the following stakeholders related to machinery safety:
---equipment manufactory;
---Health and safety agencies:
Other stakeholders affected by the level of machinery safety are:
---Equipment users;
---Equipment owner;
--- service provider;
---Consumer (when the machine is intended to be used by the consumer):
All of the above stakeholders are likely to participate in the drafting of this document:
The machinery covered by this document and the range of hazards, hazardous states and hazardous events covered are given in the scope of this document:
When the requirements of this Category C standard are different from those in Category A or B standards, the
Manufactured machines, the requirements in this Category C standard take precedence over those in other standards:
0:2 This document indicates the degree of hazards, dangerous states and events involved in elevators in case of fire:
0:3 The functions described in this document involve the automatic return of the car to the designated floor and the exit of the elevator from service:
0:4 The purpose of this document is to:
a) reduce the risk of passengers being trapped in the car in the event of a building fire;
b) After the elevator finally stops at the designated landing, it is convenient for firefighters or rescuers to confirm that no passengers are trapped in the car;
c) reduce the risk of fire or smoke exposure to passengers in the car:
0:5 This document is based on the following assumptions:
a) The recall device generates a signal that triggers specific actions of the elevator;
b) The architectural design unit and construction unit have considered the fire recall function of the elevator according to this document;
c) a clear separation between the recall device and the lift control system;
d) The recalled device works as intended:
0:6 This document assumes that the architectural design unit and the elevator supplier have negotiated on the following matters:
a) The type of recalled device and its interface (see 0:4:2 of GB/T 7588:1-2020);
b) If it is a manual recall device, the type and protective measures of the switch;
c) Specify the number and location of layers;
d) implement an appropriate maintenance and testing program;
e) When the elevator stops at the designated floor, the door remains open or closed:
Elevator characteristics in case of fire
1 Scope
This document specifies the special requirements for the characteristics of the elevator after the elevator control system receives the signal from the recalled device in the event of a fire in the building
and safety rules:
This document applies to new passenger lifts and freight lifts of all drive types: For passenger elevators and freight elevators in use, this paper
The software can also serve as a basis for improving its security:
This document does not apply to the following situations:
a) Elevators that remain in use in case of fire, such as the fireman's elevator defined in GB/T 26465;
b) Elevators used for evacuation of people in buildings, such as the elevators specified in GB/T 41122:
