VESDA-E Power Supply Units are specifically designed to complement the style and appearance of VESDA-E aspirating smoke detectors (ASDs) while providing the technical performance required by EN54-4.
The STX variants are VdS certified and CE marked to EN54-4, making them ideal for use in regions where these approvals are mandatory. These are the shallower units in the range, with depth and width matching the VESDA-E detectors for a seamless installation.
Internally, the units provide an EN54-4 certified power supply, delivering a 0.5A continuous 24V DC output while charging standby batteries (not supplied), supporting 7, 12, or uniquely 14Ah batteries. This ensures reliable 24-hour standby operation with 0.5 hours in alarm.
These units can confidently power:
Additionally, the unit includes a non-certified mode that allows powering of loads up to 1A while recharging batteries up to 12Ah, fully in accordance with EN54-4.
