The G-SPEAK ULTRA promotes the ultimate in convenience and peace of
mind by combining wireless GSM technology with CENTURION’s futuristic and
stylish ULTRA interface. Infused with the DNA of innovation, the G-SPEAK
ULTRA allows wireless communication between the user and the intercom gate
station, eectively turning the user’s phone into the intercom handset.
Filter Time: Filter Time determines how long an input event (Rising or Falling
Edge) must be present before it is recognised, i.e. an SMS or email is sent, or
a missed call is initiated. The time is set in increments of one second and the
default is 0.
Blanking Time: Blanking Time determines how long the unit will wait
between events before it will recognise the next event.
Hang Time: The time for which the call remains connected after a DTMF
event.
Any Number Mode: When enabled, this useful feature allows any number
to activate the module’s outputs, irrespective of whether they are learned into
memory. A typical application would be an event such as a wedding where
many guests need to be given temporary access. Instead of manually learning
in a 100 guests and then having to delete them again after the occasion,
the administrator can simply enable Any Number Mode and disable it again
afterward.
DTMF: Dual Tone Multi-Frequency signaling. This is used for
telecommunication signaling over analogue telephone lines in the voice-
frequency band between telephone handsets and other communication devices
and the switching centre. This allows the user to press a number on his or her
mobile handset to switch any of the outputs on the G-SPEAK ULTRA.
Channel: An electrical gateway implemented as a physical terminal on the
G-SPEAK ULTRA that provides the external interface to Input or Output signals
Called Party: When one of the Call Buttons on the Calling Module is pressed,
the Called Party is the person or persons who receives/answers the call on
their mobile phone or landline handset.
Calling Module: This can be seen as similar to a traditional intercom
gate station or entry panel that resides outside of the property and is the
component of the G-SPEAK ULTRA system that is used to dial through to and
communicate with Voice Phones.
GSM Controller: A module using 2G GSM (Global System for Mobile
Communications) technology to communicate wirelessly with GSM-enabled
handsets, allowing both audible communication and monitoring and switching
of Inputs and Outputs.
Voice Phone: A Voice Phone pertains specically to the intercom functionality
of the G-SPEAK ULTRA system, and is any learned-in phone with the ability to
communicate audibly with the Calling Module, but is also capable of activating
any of the Outputs during a call using DTMF signaling.
Switch Phone: A Switch Phone is a learned-in phone that is capable of
exercising some inuence upon the Outputs of the controller via GSM switching
and does not necessarily possess Voice Phone functionality, though it can be
learned in for both.
Access Number Proles
The access number conguration proles eliminates the hassle of conguring
input and output permissions and notications every time that a new number
is added.
Intelligent Gate Status Monitoring
With seamless integration with CENTURION gate motors, the G-SPEAK ULTRA
will let the user know when his or her gate has been left open, or is in any
other state specied by the user through intelligent monitoring of the gate
motor’s status output. Adjustable Filter settings mean that the user can specify
under which conditions they are notied about a particular gate status, for
example if the gate has remained open for longer than 20 seconds.
Supplied with activated SIM card (South Africa only)
All G-SPEAK ULTRA units are supplied with an activated Vodacom SIM card
(South Africa only). Airtime can be purchased via G-WEB (South Africa only).
Monitoring and alerting
The device can be congured to monitor up to four separate electrical devices,
such as a home alarm or even a water reservoir. It could send the user an
SMS, give a missed call or even send an email, letting the user know if the
house alarm is on or o or a reservoir is full or empty. When congured as
inputs, the unit’s four individually-congurable channels can be congured
to react to Rising Edges, Falling Edges, or both, which makes it ideal for
monitoring variable levels such as mains power. A single input can be used, for
example, to send a notication to users when mains power has failed, and the
same input can notify users once it comes back on, freeing up the other inputs
to take care of monitoring duties for other devices.
Control
When congured as outputs, the device’s dry contacts can be used to remotely
control electrical devices and appliances such as gate motors, alarms, geysers
and lights, to name but a few possible applications. Outputs can be activated
via missed call, SMS text message or by pressing a number on the user’s
phone’s touchpad.
Timed access control
(Weekly and Visitor) Set arrival and departure dates and times; guests will
only be able to activate the device’s outputs between these limits, aording
the user maximum security and aording guests maximum convenience. As a
special value-add developed specically with B & B owners in mind, customised
arrival and departure messages with welcoming messages, access instructions,
etc., can be sent automatically to guests and visitors.
Alternatively, set weekly recurring time-periods (for example 8am to 5pm,
Monday to Friday) during which users will have access to the system.
Outside of the congured time-periods, access will be denied.
Add the ability to map inputs to outputs, customise the input and output
notication messages and use the G-SPEAK ULTRA in advanced applications
and one has a powerful and convenient GSM-based monitoring and control
solution. Up to 20 separate text messages with up to ve scheduled outputs
can be congured.
Time-barring windows can be congured to block notications, activations or
specic access numbers.
Quick device associations
Devices can be associated to a G-WEB prole in a matter of seconds by simply
scanning a QR code with one’s smartphone and a third-party universal QR
scanner application.
Table 3 below lists the information shown on the dierent screens found
on the LCD interface. The left and right scroll buttons are used to toggle
between the dierent screens.
Easy access to diagnostics
This smart device provides intelligent feedback via a graphic user interface
displaying status, system information and diagnostic messages for the
complete ULTRA experience.
Smart hardware
An internal GSM antenna ensures healthier, more reliable network signal
strength without the frustration of trying to nd the optimal location to
mount the unit. If one needs to t the G-SPEAK ULTRA in a metal enclosure,
simply attach an external antenna to the onboard connector.
Time-barring per call button
Each call button can be individually time-barred. For example, the primary
button can be time-barred so that only the secondary call button works
during the evenings or early in the morning while the primary call button is
disabled.
