SR EN 54-16

EN 54-16 (SR EN 54-16:2008) – Overview

Standard Title: Systems for Fire detection and alarm

Part 16: Equipment for Control and Voice alarm signaling (original: Fire detection and fire alarm systems. Voice Alarm Control and Indicating Equipment).

It is a standard of the central system, released in 2008 in Europe (IEC EN 54-16; SR-EN 54-16) and introduced compulsory in Romania under Order 1953/2010 from 9 August 2010. Through this order is set the list with reference tokens of Romanian standards transposing harmonized European standards in the field of construction products.

SR EN 54-16: 2008 is part of the group EN-54 comprising 25 parts. This standard deals with the central equipment of the voice alarm system (VACIE).

Establishes requirements, test methods and performance criteria for control and signaling equipment of the alarm systems in buildings in which the alarm signal is in the form of tones, voice or both. Requirements of a voice evacuation system related of audibility and intelligibility not covered by this standard.

Requirements for VACIE:

  • The power supply must meet the requirements of EN 54-4

Functional Display settings:

– Wide-awakeness

– Voice alarm state

– The state of defect

– Disabling condition

  • Signaling of the power supply must be easily visible
  • Wakefulness will be signalized
  • Voice alarm status will be signalized
  • Audible warnings of states can be stopped
  • VACIE can be provided with the possibility to introduce delay at entering the voice alarm condition
  • Directed Evacuation – may exist the possibility to sync warning signals to different areas in an optimal sequence
  • May exist the possibility of manual cancellation of the alarm signal but there must be the possibility to restart it from the same level of priority
  • Should exist signals of faults: smooth supply, fuses, transmission lines, power amplifiers failure
  • Should be possible that the fault signals can be reset
  • There must be at least a general fault signal that can be transmitted. General fault signal has to be transmitted and in case of a  power failure
  • Status deactivation must be signalized
  • Status must be sent

The manual control of the voice alarm:

– Manual control must be only at a certain level of access

– Must be activated separately in areas

– Manual activation in an area will not affect the automatic operation in other areas

If there are emergency microphones they must have:

– Priority over all inputs including prerecorded messages

– A function of the microphone must open the microphone channel at the access level 2

Integrity of the transmission paths

– A fault in any transmission way  of the voice alarm system should not affect the proper functioning of VACIE

– A short circuit or interruption in the transmission path unto speaker should not affect more than one voice alarm zone for more than 100 seconds from the occurrence of the defect.

Signalings and controls accessibility 

– All mandatory signalings must be visible at level 1

–  Level 1 manual controls  must be accessible without special procedures

– Signalings and manual controls required at level 1 access must also be accessible at level 2 access

– Switching to Level 2 access must be authorized by a special procedure

– Switching to Level 3 access must be authorized by a special procedure different from previous.
