Built upon the bedrock of convenience established by the original
G-SWITCH-22 GSM module, the G-ULTRA is a complete evolution of
that device imbued with intelligence and packaged for use in a modern
environment. The combination of a smart graphic user interface and a plethora
of advanced features means that the G-ULTRA goes well beyond the scope
of mere access automation and takes remote monitoring and control to an
entirely new level.

2. Remains the property of Centurion Systems (Pty) Ltd. (South Africa Only).
Sticky Latches:
The module’s outputs can be configured to ‘remember’ their
state between power cycles. For instance, if Output 2 was active, i.e. the relay
in an energised state, and the power is removed, when power is reapplied
Output 2 will return to the activated state. This functionality is referred to as
a ‘sticky latch’ and can be enabled or disabled. Sticky latched don’t apply to
pulsed outputs and are enabled by default.
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.
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-ULTRA.
Channel:
An electrical gateway implemented as a physical terminal on the
G-ULTRA that provides the external interface to Input or Output signals
Access Number Profiles
The access number configuration profiles eliminates the hassle of configuring
input and output permissions and notifications every time that a new number
is added.
Intelligent Gate Status Monitoring
With seamless integration with CENTURION gate motors, the G-ULTRA will let
the user know when his or her gate has been left open, or is in any other state
specified 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 notified 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-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 configured 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 off or a reservoir is full or empty. When configured as
inputs, the unit’s four individually-configurable channels can be configured
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 notification 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
In addition to the four configurable channels, two extra relays are provided
which 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, SMS text message or by
pressing a number on his or her phone’s touchpad.
Table 3 below lists the information shown on the different screens found on the
LCD interface. The left and right scroll buttons are used to toggle between the
different screens.
To access the terminal blocks of the G-ULTRA, the back plate and fascia
needs to be removed. Follow the instructions below to do this.
Gently pull the two clips at the back, backward to release the main G-ULTRA
unit, and lift the unit out of the mounting plate.
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, affording
the user maximum security and affording guests maximum convenience. As a
special value-add developed specifically 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 configured time-periods, access will be denied.
Add the ability to map inputs to outputs, customise the input and output
notification messages and use the G-ULTRA in advanced applications.
One has a powerful and convenient GSM-based monitoring and control
solution. Up to 20 separate text messages with up to five scheduled outputs
can be configured.
Time-barring windows can be configured to block notifications, activations or
specific access numbers.
Quick device associations
Devices can be associated to a G-WEB profile in a matter of seconds by simply
scanning a QR code with one’s smartphone and a third-party universal QR
scanner application.
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 find the optimal location to mount
the unit. If one needs to fit the G-ULTRA in a metal enclosure, simply attach an
external antenna to the onboard connector.
