VSA-2K | Potter Sound Detection Kit with Controller, Microphone & Remote Test Annunciator

Potter · PLCs & Industrial Controllers

Description  The Potter VSA-2K Sound Detection Kit is a UL-listed, self-contained audio monitoring system designed for the protection of reverberant and non-reverberant vaults such as bank and mercantile vaults. Manufactured by Potter Electric Signal Company, LLC, this system detects abnormal acoustic signals associated with intrusion or attack. The kit includes a VSA-1 Controller/Microphone, a VSM Microphone, and an RTA Remote Test Annunciator, with expandability for up to ten microphones for enhanced coverage.     Technical Specifications  Condition New/Never Used Surplus Brand Potter Category Intrusion Detection Part Number VSA-2K Subcategory Sound Detection Kit Series VSA Series Components Included VSA-1 Controller/Microphone, VSM Microphone, RTA Remote Test Annunciator Input Power 9–16 VDC (12 VDC nominal) Operating Current 50 mA nominal / 250 mA maximum (at test) Enclosure Material High-impact halogen-free PC/ABS alloy Sensitivity Adjustment Manual, UL639 and UL681 compliant Accumulator Function 0–9 accumulated signals at 25% below alarm threshold Relay Outputs 1 Form C and 1 Form B, rated 2.0A @ 30VDC Conduit Openings Two ½" NPT Operating Temperature 32°F to 120°F (0°C to 49°C) Humidity Range Up to 85% Testing Options On-board test button and remote test annunciator Mounting Configuration Surface mount Country of Origin United States Weight 3 lbs     Information About VSA-2K The VSA-2K is part of Potter’s VSA Series, a line of microprocessor-driven sound detection systems engineered for vault and safe protection applications. It integrates automatic impedance balancing and an on-board accumulator to ensure accurate alarm response to abnormal vibration or sound. The controller and microphone are combined into one enclosure for streamlined installation and operation. Fully compatible with standard UL639 and UL681 sound detection requirements, the VSA-2K provides flexible configuration through adjustable sensitivity, remote test capabilities, and optional additional microphones for expanded zone coverage. Key Features: Complete Detection Kit: Includes controller/microphone, remote microphone, and remote test annunciator for full system setup. Expandable Design: Supports up to ten microphones for large or complex vault areas. Microprocessor-Controlled Balancing: Automatically adjusts impedance balance for stable, accurate operation. Adjustable Sensitivity: Manually tuned to detect attacks defined by UL639 and UL681 standards. Built-In Accumulator: Allows alarm activation after a defined number of sound pulses for reliable differentiation. Remote Test Capability: RTA test annunciator provides visual indicators and testing control without direct access to the controller. Durable Construction: Impact-resistant, halogen-free PC/ABS enclosure ensures long-term reliability. Multiple Relay Outputs: Provides form C and form B contacts for tamper and alarm signaling. The VSA-2K delivers the reliability and precision required for secure, code-compliant acoustic intrusion detection in vaults, safes, and other high-security enclosures.
