The CSS Sentryum 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 Sentryum 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.
The Riello UPS CSS Sentryum range is equipped with DUAL INPUT as standard on all models. This important feature allows the mandatory scheduled checks on system operation and autonomy to be carried out with extreme ease and in complete safety by simply operating an input switch. This switch interrupts the power supply to the machine without interrupting the bypass line, which is able to support the load in the event of test failure.
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 Sentryum 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 Sentryum 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 Sentryum 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.
All models are equipped with a contact interface configured in compliance with the EN 50171 standard.
In addition to the features mentioned here, the Riello UPS CSS Sentryum range has all the features of reliability and flexibility common to the UPS range it derives from, as well as offering compatibility with the main options and accessories.
