BS EN 81-28:2022 specifies the technical requirements for alarm systems in passenger and goods passenger lifts.
The core requirements cover:
1. Activation of the alarm: Defines how and when the alarm should be triggered, including under what specific circumstances.
2. Transmission of the alarm: Specifies the methods and technologies that can be used to transmit the alarm signal to a remote location or monitoring center.
3. Information for use and maintenance: Outlines the information that needs to be provided to users and maintenance personnel regarding the alarm system's operation, testing, and troubleshooting.
4. Site testing: Requires thorough testing of the alarm system on-site to ensure it meets all the requirements of the standard before the lift is put into service.
Scope: The standard applies to new and existing passenger and goods passenger lifts. It excludes failures of the communication network (e.g., mobile network signal strength) and simultaneous entrapment in multiple lifts due to network power failures.
Key objectives: The primary goal of the standard is to enhance the safety of lift users by ensuring reliable and effective alarm systems in case of entrapment or other emergencies. It aims to standardise the technical requirements for alarm systems to promote consistency and quality across the industry.
