VESDA by Honeywell (formerly Xtralis) power supply systems provide regulated, battery-backed power for multi-zone VESDA aspirating smoke detection installations. The VPS-300US extends battery backup capacity by combining a VPS-100US power supply with the VBC-001 battery cabinet, accommodating the larger battery bank needed to meet standby time requirements in data centers, server rooms, and other facilities with extended backup power specifications. Batteries are ordered separately (VBT-012, minimum 2 per power supply).

Verify panel/device family compatibility before ordering.
