VESDA Power Supply Model VPS-VEA-115UL and VPS-VEA-230UL
Operation
TThe Xtralis Model VPS-VEA-115UL and VPS-VEA-230UL are power supplies that convert a 120VAC / 60Hz or
230VAC / 50Hz respectively input to 24VDC nominal output (see specifications). They are intended for use in applications
requiring UL Listing for Fire Protective Signaling. The units must be installed in accordance with the National Electric Code
(NFPA70), the National Fire Code (NFPA72), and all other applicable local codes necessary for compliance with the local
authority having jurisdiction.
Space is provided in the VPS-VEA-115UL and VPS-VEA-230UL power supply cabinet for up to two 12V / 35AH or
36AH batteries (configured for 24V). For a larger standby capacity in a single VESDA-E VEA installation or when more than
one VESDA-E VEA detector is to be powered, use model VEA-BAT battery enclosure to house up to two 12V / 35AH or
36AH batteries or use a UL1481, ULC-S527 or UL864 Listed enclosure
Operation Overview
The VPS-VEA-115UL and VPS-VEA-230UL is a power supply intended to power the VESDA-E VEA Detector Base
Unit plus up to two (2) VESDA-E VEA Detector Stacks (see battery table). A power failure indication is provided via a
dry relay contact (Form C) which transfers due to:
1. AC input loss,
2. a low AC input voltage,
3. a loss of battery voltage,
4. a short circuit of the battery leads or
