Valcom V-9955 Auxiliary Relay Unit
Overview
The Valcom V-9955 is an auxiliary relay unit designed to expand and integrate with Valcom public address and mass notification systems. This wall or pole-mountable device provides relay control functionality to extend system capabilities across distributed installations. The V-9955 supports microphone input, making it suitable for multi-zone PA deployments where auxiliary triggering and audio routing are required. Security integrators and facility managers rely on the V-9955 to add control flexibility to existing Valcom infrastructure without requiring a complete system redesign.
Key Features
- Flexible Mounting: Wall and pole mount configurations allow installation in diverse environments, from control rooms to outdoor facility perimeters
- Microphone Support: Integrated microphone input enables direct audio source connection for live announcements and emergency notifications
- Relay Control Functionality: Auxiliary relay control extends system logic and automation capabilities across multiple zones
- System Expansion: Purpose-built to integrate seamlessly with existing Valcom PA and mass notification deployments
- Compact Design: Space-efficient form factor suitable for both indoor and outdoor mounting locations
- Multi-Zone Capable: Supports distributed audio routing and control across facility zones
Integration & Compatibility
The V-9955 integrates within the Valcom ecosystem of PA controllers, amplifiers, and speaker systems. Its auxiliary relay functionality allows technicians to expand control logic without replacing core system components. The unit's microphone input provides a direct audio integration point for emergency announcements, paging systems, and facility-wide notifications. Installation teams should verify compatibility with existing Valcom controllers and ensure proper relay wiring during deployment planning.
Deployment Considerations
The V-9955's wall and pole mount options make it suitable for both indoor facilities—including schools, hospitals, offices, and industrial plants—and outdoor deployments where relay control and audio routing are required. The microphone support enables rapid integration with existing paging infrastructure, reducing deployment complexity. Security integrators should evaluate zone architecture and relay logic requirements during the planning phase to ensure the V-9955 meets system expansion goals.

When evaluating auxiliary relay units for PA system expansion, the Valcom V-9955 offers a straightforward solution for adding control and audio input capability to mature deployments. I've encountered the V-9955 in multi-zone facilities where relay expansion was needed without full system replacement. Its microphone input support and flexible mounting make it a practical fit for both retrofit and new construction scenarios.
Technical Highlights:
- Microphone Input: Direct audio source capability streamlines integration with existing paging consoles and emergency notification interfaces
- Mount Flexibility: Wall and pole options allow deployment in control rooms, utility closures, and outdoor equipment enclosures
Deployment Considerations:
- Verify relay wiring and control logic compatibility with your existing Valcom controller configuration before installation
- Plan audio routing through the microphone input to avoid feedback loops and ensure clear signal path to amplifiers and speakers
The V-9955 works best as part of a planned system expansion rather than a standalone component. Coordinate relay requirements with your system architect to ensure proper control sequencing across zones. This unit delivers solid relay functionality without unnecessary complexity.
