HIGHLIGHTS
The CSS Sentinel Tower by Riello UPS is designed in compliance with standard EN 50171 and is therefore the ideal solution for installation in buildings subject to fire safety regulations and in particular for the power supply of emergency lighting systems. This is not all however, according to local regulations the CSS Sentinel Tower range by Riello UPS is also suitable for supplying power to other emergency systems such as automatic fire extinguishing systems, alarm systems and emergency detection systems, smoke extraction equipment and carbon monoxide detection devices as well as dedicated security systems in sensitive areas. The use of centralised supply systems (CSS) ensures a significant reduction in system set-up and maintenance costs as well as making periodical checks simpler and faster to perform.
HIGH RECHARGE CURRENT AND BATTERY CARE SYSTEM
Proper battery care is critical to ensuring correct CSS operation in
emergency conditions. The Riello UPS battery care system consists of
a series of features and capabilities designed to obtain the best
performance, extend operating life and satisfy the recharge times
imposed by the standard. The Riello UPS CSS Sentinel Tower range
is designed in compliance with standard EN 50171 and ensures high
current levels are available for the batteries, allowing recharge of up
to 80% of full autonomy within 12 hours. Riello UPS CSS Sentinel Tower
are suitable for use with hermetically sealed lead-acid (VRLA), AGM and
GEL batteries and Open Vent and Nickel batteries. Different charging methods
are available depending on the battery type. The recharge voltage
compensation function based on temperature prevents excessive battery
charges and overheating. The deep discharge protection prevents reduced
battery performance and battery damage.
HIGH OVERLOAD CAPACITY
As required by standard EN 50171, the Riello UPS CSS Sentinel Tower
range is designed and sized to support continuous overloads (with no
time limits) of up to 120% of nominal load.
PROTECTION AGAINST BATTERY INVERSION
Mandatory in line with standard EN 50171, protection against battery
inversion ensures the safety of those carrying out maintenance operations
on the devices and at the same time prevents damage to the system in
the event that the batteries are inadvertently connected with the
wrong polarity.
CONTACT INTERFACE
All models are equipped with a contact interface configured in compliance
with the EN 50171 standard.
