LEGRAND’S extensive range of uninterruptible power supply (UPS)
systems encompasses solutions designed especially for the protec-
tion of data in small offices, commercial environments and home
applications.
“Niky and Niky S UPS single phase systems, which ensure a safe
and reliable power supply from 600 VA to 3000 VA, have been
developed by Legrand for quick installation and easy configuration,”
says Sonja Leibbrandt, marketing and pricing manager, Legrand
SA. “These compact microprocessor controlled UPS systems have
an electronic automatic voltage regulator (AVR), an intelligent
communication interface and integrated self-diagnostics to
provide reliable protection of the installation.”
Other features include a cold start function, an RS-232 or USB
interface and modem/LAN telephone protection. Buttons and LED
signalling provide real time control of the status of the UPS system.
Niky line interactive UPS: Single phase VI systems, with IEC
multi-socket outlets and a pseudo-sinusoidal waveform, offer
a back up time between 5 and 30 minutes. This system offers
advanced management according to battery discharge level.
Niky S line interactive UPS: Single phase VI-SS systems have
a sinusoidal waveform output, excellent voltage regulation and
intelligent battery management, to offer protection against voltage
peaks, as well as over-load and short-circuit protection. The back
up time of this system, which is either eight or nine minutes, is
measured under optimum operating conditions.
A range of communications accessories has been designed for
managing and configuring the UPS, as well as for
remote control of the system. The UPS systems
are available in convenient, user-friendly
packaging and are supported throughout the
country by Legrand and its carefully selected
distributor network.

UPS SYSTEMS DESIGNED FOR SAFE AND RELIABLE POWER SUPPLY
Legrand’s Niky and Niky S UPS single phase systems ensure a safe and
reliable power supply from 600 VA to 3 000 VA.
JOHNSON CONTROLS has launched a new line
of BACnet thermostats. The T8800 series is de-
signed for growing the network thermostat market
and features Building Automation Systems (BAS)
integration capabilities that enable remote moni-
toring and programmability for efficient tempera-
ture control. The T8800 series supports 2pipe or
4-pipe FCU applications.
Says Neil Cameron, Johnson Controls area
general manager: Building Efficiency: Africa, “We
are seeing an increasing requirement to integrate
multiple HVAC and BAS components and systems
in the South African market. The T8800 series
allows companies to seamlessly incorporate an
aesthetically modern yet simple to use touchscreen
device into their existing BAS and fan coil HVAC
environments”.
Temperatures and timers can be modified
through the thermostat,enabling businesses to drive
more efficiency with regards to energy consumption
and deliver more flexibility for a comfortable and
productive environment. The thermostat can be
used with heating and cooling fan coil units.
Features and specifications:
• BACnet MS/TP communication –
supporting BAS integrations for up to 100
devices on Metasys Engines.
• Modern design – touch screen, featuring
easy user interface.
• Wide applications for fan coil units –
models available are on/off, proportional
with 3-speed fan control.
• Energy saving – occupied/unoccupied
mode selection.
• Accepts remote temperature sensors –
connect to remote type II 10K NTC (e.g.,
TE-636S-1).
• BTL Certified – BACnet Testing Laboratories
Protocol Revision 12 (BTL) Listed BACnet
Application Specific Controller (BASC).
• Colour options – customised colour options
for orders of 300 or more.
