Potter Electric PL-VSA2K Vault Sound Alarm System

The Potter Electric PL‑VSA2K is a professional-grade vault sound alarm system engineered to provide primary protection for both reverberant and non-reverberant vaults—commonly used in banking, jewelry, cash-handling, and high-value storage facilities. The kit includes a VSA-1 controller with built-in microphone, an additional VSM microphone, and an RTA remote test annunciator. The system continuously listens for acoustic disturbances (e.g., drilling, glass breakage), and triggers a high-level alarm if sound pulses exceed preset sensitivity thresholds. Sensitivity is manually adjustable to meet UL-639 and UL-681 standards. A built-in accumulator monitors sound events over 10 minutes (0–9 pulses), reducing nuisance alarms. It features push-button balancing, on-board test sounder, remote test capability via RTA LEDs and switch, and an optional self-test function to validate system health. The unit integrates seamlessly with existing alarm panels, offers durable PC/ABS enclosures with tamper detection, and operates in 32–120 °F environments. Designed for easy expansion—supporting up to ten microphones per system—it provides robust, reliable acoustic intrusion detection.
