The section of IEC 839-5 specifies the general requirements for equipment used in alarm systems. It does not specify the equipment used to display the information at the alarm receiving centre or installation of the equipment. Additional requirements for specific types of alarm transmission systems are given in separate sections as part of IEC 839-5. This does not preclude the use of any alarm transmission system not covered by any one of these specific sections, provided...
