European standard EN 54 specifies requirements for all component parts of a fire alarm system

Fire alarm system

An automatic fire alarm system is designed to detect the unwanted presence of fire by monitoring environmental changes associated with combustion. In general, a fire alarm system is classified as either automatically actuated, manually actuated, or both...

. In the United Kingdom it superceeded BS 5445:Part 1:1977. BS EN 54-1:1996 was published in December 1996.

The standard has been published in a number of parts:

• EN 54 part 1 Fire detection and fire alarm systems. Introduction

• EN 54 part 2 Fire detection and fire alarm systems. Control and indicating equipment (Fire alarm control panel
  Fire alarm control panel
  A Fire Alarm Control Panel , or Fire Alarm Control Unit , is the controlling component of a Fire Alarm System. The panel receives information from environmental sensors designed to detect changes associated with fire, monitors their operational integrity and provides for automatic control of...

  Smoke detector
  A smoke detector is a device that detects smoke, typically as an indicator of fire. Commercial, industrial, and mass residential devices issue a signal to a fire alarm system, while household detectors, known as smoke alarms, generally issue a local audible and/or visual alarm from the detector...
