Description
The line splits into three series, CSS Sentinel Tower at 3–5 kVA (1:1), CSS Sentryum at 6–120 kVA (1-3:1 and 3:3) and CSS Master at 100–600 kVA. The system carries a 120 % overload with no time limit, so luminaire inrush when all circuits start at once does not trip it. The charger restores up to 80 % of autonomy in 12 h. It works with VRLA, AGM, GEL, vented lead-acid and nickel batteries, including those with a 10-year service life, and the battery input is protected against reverse polarity. CSS Sentryum and CSS Master have a dual input, so rectifier and bypass can run from separate feeds. The contact interface follows EN 50171 and reports status to the fire alarm panel, and the enclosure meets EN 60598-1.
How to choose
Size the power from the total of emergency luminaires and other safety loads plus margin, and let the supply decide the series. A single-phase panel in a small building is covered by CSS Sentinel Tower 3–5 kVA, and a three-phase supply with loads up to 120 kVA takes CSS Sentryum with 3:1 or 3:3 output. Large sites from 100 kVA up go to CSS Master. Autonomy and battery type come from the design, and batteries with a 10-year life cut maintenance visits.
