INSTALLATION, COMMISSIONING AND USER MANUAL

Activate the All-call control. The red indicator illuminates steady
4
All the Call indicators flash

As the WIP handsets are taken off hook the associated Call indicator goes steady
to indicate the half duplex call the WIP handset has been established.
6
Calls to the WIP handsets can be terminated at the WIP, by placing the WIP on
hook, at the EICIE by activating the Call control, or by placing the handset at the
EICIE on hook.
5.5.6 Networked EICIE
The EIS can consist of a network of EICIEs.
When establishing a call from a EICIE handset to a WIP handset, the same procedure as detailed in
section 5.5.2 is followed, except when the handset at the EICIE is taken off hook, the EICIE in CTRL
indicator (see section 5.1.17) is illuminated in all other EICIEs to show that the EIS is in use.
When establishing a call from a WIP handset to a EICIE handset, the same procedure as detailed in
section 5.5.3 is followed, except all EICIE handsets ring, and the first EICIE handset taken off hook has
control of the EIS and can answer the call from the WIP. Once the call has been answered at an EICIE,
all EICIE handsets cease ringing and the EICIE in CTRL indicator is illuminated in all other EICIEs to
show that the EIS is in use.
The EIS has the same priority scheme as the EWS (see clause 5.4.3).
If the handset at an EICIE with a higher priority is taken off hook while the EIS is in use, then the current
calls in progress are transferred to the EICIE with the higher priority. The WIP handsets that are off hook
will revert to the ring tone and the calls can be established at the higher priority EICIE as required.
The handset at the lower priority EICIE is treated as a WIP handset – and will revert to a ring tone. A
call between the higher priority EICIE and the lower priority EICIE can be established if required.
If a handset at a lower priority EICIE is taken off hook while the EIS is in use, then ring tone is present
in the earpiece, and the call can be established with the higher priority EICIE if required.
If the EWS is in manual mode, then the EWCIE that is in control, shall also be in control of the EIS.
5.5.7 Ring, On Hold and Confidence Tones
The ring and confidence tones are based on the requirements specified in AS/CA S002 – as stated in
the NOTE of clause 7.3 of AS 4428.4:2016.
The tones are a combined signal of 400Hz and 450Hz.
The Ring and On-hold tones are the same.
Due to the requirements of clause 7.3.4 and 7.3.5 of AS 4428.4:2016, the cadence specified in S002
(0.4s on, 0.2 s off) could not be followed.
The cadence used is 0.5 sec on and 0.5 sec off – to meet the requirement of clause 13.7.2 of AS
4428.4:2016 (Clauses 7.3.4 and 7.3.5 require the cadence to match the flash rate of the call indicator,
and clause 13.7.2 specifies the allowable flash rate of the call indicator)
