EWCIE and EICIE incorporating a user interface shall be installed in a location complying with the following requirements:
(a) The area shall be secure from unauthorized access. Where this is not possible the controls shall be secure from unauthorized access.
(b) The ambient noise level shall be not greater than 70 dB(A).
NOTE: This Standard expects the ambient noise level to be assessed taking into consideration the unusual circumstances of an emergency. For example, during a fire, it is expected that a fire brigade booster pump may be operating outside the building, possibly increasing the noise level in the lobby area above 70 dB(A). The lobby area in this case would be unsuitable,unless provisions were made for its acoustic isolation.
(c) Access shall not be obstructed.
(d) Operation shall not obstruct the evacuation of the building.
(e) Ambient lighting conditions shall not adversely affect the ability to interpret the state of visual indicators, and the reading of displays and labels.
(f) All controls and indicators shall be not less than 750 mm and not more than 1 850 mm above floor level.
(g) Equipment shall be located in an area that presents a low risk of damage to the equipment and low risk of injury to personnel in an emergency.
(h) Where the EWCIE and/or EICIE is obscured by a door, that door shall be marked in a contrasting colour to the general colour scheme with the words ‘EWIS PANEL’ or ‘EIS PANEL’ or ‘EWS PANEL’, whichever is applicable CIE in letters not less than 50 mm high. There shall be no other lettering on the door unless the door also obscures a FDCIE. The door shall not be lockable. Where the door reduces the CIE sounder sound level below the requirement, means shall be provided to give the required sound level outside the covering door.
NOTE: It is recommended that a telephone, with access to the public network, be provided in the vicinity of the installed location.AS 1670.4 pdf free download.
