The Gent S4-34450 4 Channel I/O Interface (PCB Only) is a specialized, loop-powered circuit module engineered to expand the control and monitoring capabilities of addressable fire alarm networks. Supplied strictly as a standalone printed circuit board (PCB) without an outer plastic enclosure, this unit is designed for direct integration within existing fire panel cabinets, command centers, or specialized multi-interface enclosures.

By offering four independent input channels and four independent low-voltage output channels on a single board, the S4-34450 provides highly customizable zoning and triggering logic while optimizing loop capacity and reducing physical hardware requirements.

Key Features & Functionality

• Compact PCB-Only Format: Supplied without a standard outer box, making it perfect for clean, high-density installations inside main control panels, repeater panels, or dedicated equipment racks.

• 4-Channel Independence: Features 4 inputs and 4 low-voltage outputs on a single card, delivering extensive input/output capability without exhausting loop addresses.

• Loop-Powered Operation: Draws all necessary power directly from the fire alarm loop, eliminating the need for local external power supplies and streamlining the installation process.

• Low-Voltage Auxiliary Control: Securely interfaces with low-voltage external circuits to execute automated emergency responses across integrated building systems.

Common Applications

Designed to be mounted inside main fire panel enclosures or technical cabinets to manage:

• HVAC plant shutdowns, air conditioning overrides, and smoke damper control.

• Centralized access control integration and magnetic door release overrides during an evacuation.

• Monitoring external statuses from third-party systems (e.g., fire pump faults, generator status, or gas suppression release).

• Triggering low-voltage remote indicators and auxiliary signaling equipment.
