2.1.6 alarm signal, or condition, warning of an emergency 2.1.7 alarm indication indication [at the indicating equipment, see Figure 1, items B and M) to show that a detection signal has been received 2.1.8 alert signal audible signal complying with ISO 7731 or visual signal or a combination of audible and visual signals that call attention to the possibility of a hazardous or dangerous situation 2.1.9 alphanumeric display indicator capable of giving information by the display of messages consisting of text and/or numeric characters 2.1.10 analogue detector detector which gives an output signal representing the value of the sensed phenomenon Note 1 to entry: This may be a true analogue signal or a digitally encoded equivalent of the sensed value. 2.1.11 ancillary equipment equipment which supports fire detection and fire alarm functions not currently defined in ISO 7240 Note 1 to entry: See Figure 1, item N.2.1.12 ancillary function action performed by equipment not related to fire detection or fire alarm system Note 1 to entry: See Figure 1, item 0. 2.1.13 aspirating smoke detector smoke detector, in which air and aerosols are drawn through a sampling device and carried to one or more smoke-sensing elements by an integral aspirator (e.g. fan or pump) Note 1 to entry: Each smoke sensing element may contain more than one sensor exposed to the same smoke sample. 2.1.14 audible alarm device AAD component intended to signal an audible warning of fire to the occupants of a building Note 1 to entry: AADs are sometimes referred to as“fire alarm sounders’ ‘. 2.1.15 cabinet housing that affords a degree of protection and robustness to its constituent parts and subassemblies2.1.19 commissioning process that verifies the installed equipment or system meets the defined requirements 2.1.20 compatibility ability of a component of a FDAS to operate with another component of the same FDAS 2.1.21 competent person person who, in relation to the work undertaken, has the necessary knowledge, skill, and experience to complete the work satisfactorily and without danger or injury to any person 2.1.22 component device contained in one housing performing at least one or part of a function of a FDAS EXAMPLE Fire detectors, alarm devices, and control and indicating equipment are components of a FDAS. Note 1 to entry: Where a function is distributed in separate cabinets, each cabinet is considered as a separate component. 2.1.23. configuration arrangement of components of a FDAS specified by number, type, and topology, together with any necessary limits on the transmission paths 2.1.24 confirmation signal signal from a fire detector or manual call point which terminates a first alarm state.AS ISO 7240.1 pdf download.
