VESDA VPS-220-STX5 Power Supply 0.5A (7-14AH) Black

The VESDA VPS-220-STX5 is an EN 54-4 certified 24V DC power supply designed to match the width, depth and curved styling of VESDA-E aspirating smoke detectors. It provides a 0.5A continuous 24V DC supply while charging standby batteries of 7, 12 or 14Ah, giving 24 hours standby plus 30 minutes in alarm for a VESDA VLF-500, VESDA-E VEP or VESDA-E VES detector, and for VESDA-E VEU detectors up to fan speed 5.

This is the matt black version, which suits the black plastic VESDA-E detectors. An internal channel accommodates the detector exhaust, which is useful when the 25mm exhaust pipe has to be run back to the protected area.

Key features

• Styled to blend with VESDA-E detectors, with cable knockouts that line up with the detector enclosure
• Can be mounted directly below a VESDA-E detector, or above an inverted detector
• Temperature-compensated battery charging to maximise battery life
• Regular battery impedance checking
• Can run on batteries alone, which is useful during commissioning before mains power is available
• Front-panel OK and fault LEDs plus an internal status LED
• Changeover fault relay for monitoring via the VESDA-E general purpose input (GPI) or the fire alarm panel
• DIP switch configuration, including battery monitoring, charge current, battery resistance threshold and mains failure simulation
• Non-certified setting allows loads up to 1A with batteries up to 12Ah
