Xtralis Power Supply Units are uniquely designed to complement the style and appearance of Xtralis aspirating smoke detectors (ASD) and are technically matched to provide suffi cient current and battery charging capacity to meet the requirement of EN 54-4.
The VPS-220-U and VPS-215-U models are LPCB approved and CE marked to the EN54-4 so are particularly suitable for use in territories where these approvals are required. It may also be suitable in territories where ISO 7240-4 is required.
Style U product range
VPS-220-U: 0.5 A load / 14 Ah batteries (max)
This is the premier unit. Designed with the same foot print, color and layout as the VESDA VLP and VESDA VLS, the power supply will visually blend with the detectors.
Internally is an EN54-4 approved Power Supply rated to provide a 0.5 amp continuous 24 Vdc supply while also charging the batteries (not supplied) which can be a 7, 12 or uniquely, 14 Amp/hr arrangement making it suitable for most multi-pipe ASD systems.
With regard to installation, cable entry knockouts all line up with the VESDA VLP and VESDA VLS enclosure allowing positioning of the power supply directly adjacent to the detector. The front cover supports 2 LEDs giving a quick visual indication of OK and/or fault condition.
VPS-215-U: 0.5 A load / 7 Ah batteries (max)
This is the budget unit. It is intended as a low cost unit to supply a single pipe ASD detector which only requires 7 Ah batteries. A simple but elegant construction and no LEDs on the lid keep the cost of the unit to a minimum.
This unit is still engineered to compliment the product with cable entry knockouts lining up with the cable entries on various Xtralis detectors. The unit can also be inverted where necessary. The internal charger is EN54-4 approved and internal LEDs are provided to indicate OK and Fault.
