EN 54-11 Fire detection and fire alarm systems — Part 11: Manual call points
1 Scope
This European Standard specifies the requirements and methods of test for manual call points in fire detection and fire alarm systems in and around buildings. It takes into account indoor and outdoor conditions, the appearance and operation of the manual call points for type A “direct operation” and type B “indirect operation” and covers those which are simple mechanical switches, those which are fitted with simple electronic components (e.g. resistors, diodes) and those which contain active electronic components and which work with the control panels for signalling and identifying, for example, an address or location.
This European Standard does not cover manual call points for special applications, for example manual call points that are intrinsically safe or for use in hazardous conditions, if such applications require additional or other requirements or tests than those given in this standard.
2 Normative references
This European Standard incorporates, by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments).
3 Terms and definitions
For the purposes of this European Standard, the terms and definitions given in EN 54-1:1996 apply together with the following.
3.1
alarm condition
the condition of the manual call point after the operating element has been activated
3.2
frangible element
a component which is glass or has the appearance of glass and which after receiving a blow or pressure as instructed, is physically broken or is visibly displaced by change of position and remains in that condition until replaced or reset
NOTE The frangible element is intended to give protection against unintentional operation and to be a deterrent against misuse. The visible displacement of the frangible element is accepted as apparent breaking.
3.2.1
non-resettable frangible element
a frangible element that needs to be replaced after the activation of the manual call point, in order for the manual call point to be able to return to the normal condition
3.2.2
resettable frangible element
a frangible element that can be returned to its original position without replacement, in order for the manual call point to be able to return to the normal condition
3.3
front face
ISO 3864
the area within the outline of the front view of the manual call point excluding the area of the operating face NOTE SEE FIGURES 1 AND 2, ITEM 1.
3.4
manual call point
a component of a fire detection and fire alarm system which is used for the manual initiation of an alarm [EN 54-1:1996]
Manual call points are divided into two types depending on the method of operation:
3.4.1
type A: direct operation
a manual call point in which the change to the alarm condition is automatic (i.e. without the need for further manual action) when the frangible element is broken or displaced
3.4.2
type B: indirect operation
a manual call point in which the change to the alarm condition requires a separate manual operation of the operating element by the user after the frangible element is broken or displaced
3.5
normal condition
the condition in which the frangible element is undamaged and the manual call point is operating without giving an alarm or fault signal
3.6
operating element
mechanical and electrical switching element; the part of the manual call point which initiates the alarm signal when operated
3.7
operating face
that area of the manual call point which may be the visible part of the frangible element or the visible area behind it
NOTE See Figures 1 and 2, item 2.
3.8
special tool
a device not normally carried by the public (e.g. a key), normally provided by the manufacturer and which is used for replacing or resetting the frangible element
NOTE It is intended to deter unauthorized access to the manual call point, while being available on site either at a defined location or from a “responsible person” familiar with and having knowledge of the system.
