The POTTER ELECTRIC SIGNAL CO. US EVD-M is an expandable master vibration and shock detector unit designed for security and fire alarm applications. This device serves as the primary control point in a networked detection system, allowing additional sensor nodes to be connected as the installation grows. Security and alarm technicians install this unit where early detection of vibration or physical impact events is required, such as in vault protection, perimeter security, or structural monitoring systems. Its expandable architecture makes it a practical choice for facilities that anticipate phased buildouts.
The EVD-M is suited for commercial and light-industrial environments where vibration and shock sensing is part of an integrated alarm or access-control strategy. As a master unit, it coordinates signals from connected detector nodes and communicates alarm events to the broader system. Installers working on new construction or retrofit projects can scale the system by adding compatible expansion units without replacing the master device. Typical applications include safes, vaults, windows, doors, and structural panels requiring tamper or impact detection.
Designed as an OEM-style master unit for expandable vibration and shock detector systems requiring a primary control device with network expansion capability.
Installation should be performed by a licensed alarm or low-voltage technician in accordance with applicable local codes and NFPA standards. Power down the alarm panel or control system before wiring the master unit to avoid damage to connected equipment. Secure the unit firmly to the protected surface to ensure accurate vibration and shock sensing. Consult the manufacturer installation manual for terminal wiring diagrams and sensitivity adjustment procedures.
