Protech by Hirsch presents the XL‑MINISOUNDER, the compact audible walk tester supplied as the standard sounder with most PIRAMID intrusion sensors. Designed to simplify commissioning and verification, the XL‑MINISOUNDER emits clear audible cues during walk testing, allowing installers to instantly confirm detection performance without relying on external tools or visual indicators alone. As a direct replacement component, it maintains full compatibility with PIRAMID sensor platforms and for ongoing maintenance, field tuning, or sensor repositioning. Ideal for technicians who require quick, precise feedback while optimizing PIRAMID detection coverage.
