4 Requirements
4.1 General
4.1.1 FDCIE shall have provision for grouping the signals from points to provide zonal indications.
4.1.2 The processing of signals shall give the highest priority to the indication of fire alarms.
4.1.3 FDCIE shall be capable of unambiguously indicating the following functional conditions, in accordance with 4.3 to 4.8:
— quiescent condition;
— fire alarm condition;
— fault warning condition;
— disablement condition, where the condition is provided;
— test condition, where the condition is provided;
— supervisory signal condition, where the condition is provided.
4.1.4 FDCIE shall be capable of being simultaneously in any combination of the following
functional conditions:
— fire alarm condition;
— fault warning condition;
— disablement condition, where the condition is provided;
— test condition, where the condition is provided;
— supervisory signal condition, where the condition is provided.
4.2 Compliance
4.2.1 In order to comply with this document, FDCIE shall meet the following requirements.
a) Clause 4, which shall be verified by visual inspection or engineering assessment, shall be tested in accordance with Clause 5 and shall meet the requirements of the tests.
b) Clause 7 and 8, which shall be verified by visual inspection.
4.2.2 If an optional function with requirements is included in FDCIE, then all the corresponding requirements shall be met (see Annex A for a list of optional functions).
4.2.3 If functions other than those specified in this document are provided, they shall not jeopardize compliance with any requirement of this document.
4.3 Quiescent condition
Any kind of system information may be displayed during the quiescent condition. However, no indications shall be given which could be confused with indications used in the
— fire alarm condition,
— fault warning condition,
— disabled condition,
— test condition, or
— supervisory signal condition.
4.4 Fire alarm condition
4.4.1 Reception and processing of fire signals
4.4.1.1 FDCIE shall enter the fire alarm condition when signals are received which, after any necessary processing (see Annex B), are interpreted as a fire alarm.
4.4.1.2 FDCIE shall be capable of receiving, processing and indicating signals from fire detection zones. A signal from one fire detection zone shall not falsify the processing storing and/or indication of signals from other fire detection zones.
4.4.1.3 Except where 4.4.11 or 4.4.12 applies, the time taken by scanning, interrogation, or other processing of signals from fire detectors, in addition to that required to take the fire alarm decision, shall not delay the indication of the fire alarm condition, or of a new fire detection zone in alarm by more than 10 s.
4.4.1.4 FDCIE shall enter the fire alarm condition within lOs of the activation of any manual call point.
4.4.1.5 The mandatory indications and/or outputs shall not be falsified by multiple fire signals received from the same or different detection circuits as a result of the simultaneous operation of two points, the operation of further points or both.AS 7240.2 pdf download.
