AS 1603.17:2020 pdf download.Automatic fire detection and alarm systems Part 17: Warning equipment for people with hearing impairment.
3.1 General
Components may be supplied in two ways:
(a) A standalone system containing the components, connections and instructions required for that installation; or
(b) Individual components intended to be installed as part of another warning system.
Components shall be compatible when interconnected to form a system.
Leads connecting a component with the control panel shall be provided with a strain-relieving device.
The lead shall be subjected to a pulling force of 20 N without jerks for I mm in any direction allowed by the design. The pull shall not be transmitted to the joints between the leads and terminal connectors or between the leads and circuit board.
3.2 Control panel
3.2.1 General
The control panel may be a standalone unit, conforming to this document, or it may be incorporated
into the control and indicating equipment (CIE) as specified in either AS 1670.1 or AS 1670.4.
The indications and controls shall be designed so that they are easily accessible.
The control panel shall be able to function in the following conditions simultaneously:
(I) Alarm condition.
(ii) Fault warning condition.
All components, including flexible mains supply cord and cables, shall meet the relevant requirements of AS/ACIF S008, AS/NZS 60335.1 and AS/NZS 62368.1.
3.2.2 Wired component connectors
Wired connections between system components shall be via mechanically latching connectors or screw terminals.
Where mechanically latching connectors are used, it shall not be possible to make these connections incorrectly.
3.2.3 Transmission path fault supervision
External transmission paths between the warning system components shall be supervised for faults that may prevent the transmission of an emergency warning signal.
Where the transmission path is by means of physical connections (e.g. cabled), a transmission path fault shall be indicated at the control panel within 300 s.
Where the transmission path is by means of wire-free connections, a transmission path fault shall be indicated at the control panel within 60 mm.
3.2.4 Enclosure protection
The enclosure ingress protection shall meet at least classification IP 21C as given in IEC 60529.AS 1603.17 pdf download.
