Introduction

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.

Elevator remote alarm system

1 Scope

GB/T 24475-2023 covers the alarm system through which a passenger shut inside a lift car reaches a rescue service. The safety requirements and risk reduction measures deal with how the alarm is triggered and how the call is transmitted onward, and an informative annex sets out what a typical two-way exchange between the lift and the rescue organization has to carry, so that the person answering learns which building and which lift is involved and the trapped passenger hears a human voice rather than a tone. The usage information clause covers what has to be passed on about use and maintenance, and the document also fixes the on-site test to be carried out before the lift is put into service — an alarm that is installed but never exercised is the one that fails on the day it is needed, and by then nobody is in a position to report it. As a type C standard under the GB/T 15706 machinery safety framework, it names the significant hazards, hazardous situations and hazardous events that go with a lift used as intended. Written for lift manufacturers and installers, maintenance companies, alarm and monitoring service providers, and the bodies that inspect lifts in service.

This document specifies the alarm triggering and transmission of the alarm system, the use and maintenance information, and the requirements for on-site testing before the elevator is used.

Require.

This document describes the significant hazards, hazardous states and hazardous events associated with lifts, namely. when the lift is used as intended and

In the event of reasonably foreseeable misuse, the user is at risk of being trapped in the car and shaft.

This document applies to the alarm systems of passenger lifts and freight lifts.

This document does not apply to.

a) communication network failure (see Appendix A), including mobile network signal strength or the like;

b) The power supply network breaks down, causing the elevators in this area to fail simultaneously;

c) The elevator remote alarm system installed before its implementation.
