Part 17: Warning equipment for people with hearing impairment.
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 1 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 he indicated at the control panel within 60 min.
3.3 Display of functional conditions
The control panel shall be capable of unambiguously indicating at least the following functional conditions by means of light-emitting indicators or alphanumeric display or both, as described in Clause 3.4.1:
(a) Alarm condition.
(b) Fault warning condition.
3.4 Control panel indications
3.4.1 General
The control panel indicators shall meet the requirements alAS 7240.2:2018 Clause 4.11.
3.4.2 Indication of power
The presence of power shall be indicated without prior manual intervention. This indication of power shall —
(a) consist of a dedicated green light-emitting indicator or an alphanumeric display or both; and
(b) meet the requirements of Clause 3.4.1.
Components that are not powered by the control panel shall incorporate a power on indicator unless the provision of power is supervised by the control panel.
3.4.3 Indication of an alarm condition
An alarm condition shall be visually indicated without prior manual intervention. This indication of an alarm condition shall —
(a) consist of a dedicated red light-emitting indicator or an alphanumeric display or both; and
(b) meet the requirements of Clause 3.4.1.
NOTE This visual indicator Is not the visual alarm device.
The control panel shall respond to the alarm signal from an initiating device and activate the warning equipment within 15 s.
3.4.4 Indication of a fault
A visual indication shall be given on the control panel of any of the fault conditions listed in Clause 3.6.2.AS 1603.17-2020 pdf download.
