1 Scope

GB 19880-2024 is the Chinese product standard for manual fire call points, the break-glass and press-here units on the wall by every exit. They are the simplest device in a fire alarm system and one of the most regulated, because they are the only part of it a member of the public operates, and because a false alarm from a badly designed one costs an evacuation. The standard is mandatory and it is the basis of the CCC certification the product needs. It sets the classification and the requirements: on the operation, the force required and the indication that the point has been operated, on the resettability and the means of resetting, on the marking and the legibility of the instruction, on the electrical requirements and the signals sent to the control panel including the addressable case, on the enclosure and its degree of protection, on the mechanical strength and the impact resistance, on the resistance to heat, cold, humidity, corrosion and vibration, and on the electromagnetic compatibility, together with the test methods and the inspection rules. The 2024 edition replaces GB 19880-2005.

This document specifies the classification, requirements, inspection rules, marking and instructions for use of manual fire alarm buttons, and describes the corresponding tests method. This document applies to the design, manufacture and inspection of manual fire alarm pushbutton products used in industrial and civil buildings.
