Introduction
The fire detection control and indication function (ISO 7240-1:2014, Figure 1, item B), within a fire
detection and alarm system (FDAS) installed in and around buildings, is provided by the fire detection
control and indicating equipment (FDCIE).
FDCIE receives signals from the fire detection function (ISO 7240-1:2014, Figure 1, item A) and the
manual initiating function (ISO 7240-1:2014, Figure 1, item D). FDCIE processes received signals and
may indicate information at the FDCIE and/or send signals to other functions within the fire detection
and alarm system. The signals are used to provide notification to building occupants and other parties
responsible for building safety in accordance with the design objectives for the fire detection and alarm
system (see also ISO 7240-14 or equivalent national design standard).
This document is drafted on the basis of mandatory functions, which are provided on all fire detection
control and indicating equipment, and optional functions (with requirements) which may be provided.
It is intended that the options be used for specific applications, and to meet the fire detection and alarm
system design objectives. Each optional function is included as a separate entity, with its own set of
associated requirements, in order to permit fire detection control and indicating equipment with many
different combinations of functions to comply with this document.
Other functions associated with fire detection and fire alarm may also be provided, even if not specified
in this document.

management of the FDAS.
4.4.4.2 The audible indication shall not be silenced automatically.
4.4.4.3 Silencing the audible indication may be accompanied by changes in the visual indications
of fire alarm (e.g. the indication of light emitting indicators may change from flashing to steady or the
information given on the alphanumeric display may be updated), provided that the conditions are still
indicated as required in this document.
4 © ISO 2017 – All rights reserved
4.4.4.4 The audible indication shall re-sound for each new fire detection zone in alarm. If the option
in 4.4.8.1 d) 3) is provided, then a new alarm in the same detection zone shall also re-sound the audible
indication.
4.4.5 Other indications during the fire alarm condition
4.4.5.1 If faults, disablements or tests are indicated by means of separate light-emitting indicators, and
such indications are suppressed in the fire alarm condition, it shall be possible to reveal these by means
of a manual operation at access level 1 or 2.
4.4.5.2 If the fire alarm indications are on an alphanumeric display, the following shall apply to the
display of other information on the alphanumeric display.
a) Information not related to the fire alarm condition shall be suppressed unless the display has more
than one window, one of which is exclusively reserved for fire alarm indications.
b) Suppressed indications of faults, disablements and optionally, test or supervisory modes, shall
each be capable of being displayed at any time by manual operations at access level 1 or 2. These
operations shall be different from, or additional to, that specified in 4.4.3.2 d) for displaying fire
detection zones in alarm and shall display the suppressed indications independently of each other.
c) Fields or the alarm window, may be temporarily suppressed to permit the display of faults,
disablements and optionally, test or supervisory modes, however, the display shall meet the
requirements of 4.4.3.2 a), 4.4.3.2 b) and 4.4.3.2 c) within 30 s of the suppression.
4.4.6 Reset from fire alarm condition
4.4.6.1 FDCIE shall be reset from the fire alarm condition at access level 2, by means of a separate
manual control, or as specified in 4.6.1.5 or 4.9 (if provided). This control shall be used only for reset and
may be the same as that used for reset from the fault warning condition.
4.4.6.2 Following a reset operation, the correct functional conditions, corresponding to any received
signals, shall either remain, or be re-established within 60 s. Reset shall either be completed within 20 s
following the manual operation, or where a reset cannot be completed in 20 s, it shall be indicated within
20 s that the reset process is running.
4.4.7 Output of fire alarm condition
4.4.7.1 At least one output that signals the fire alarm condition shall be provided, which may be an
output in accordance with 4.4.8, 4.4.9 or 4.4.10.
