GRI 4561R Tilt Sensor with Relay

GRI 4561R Tilt Sensor with Relay

Overview

The GRI 4561R is a tilt sensor with integrated relay output designed for security integrators and access control installers. This sensor detects angular displacement and triggers relay contacts to activate downstream circuits, making it suitable for door position monitoring, window detection, and perimeter security applications. The 4561R combines reliable tilt detection with fail-safe relay switching to provide a straightforward integration point for both wired access control systems and standalone security circuits.

Key Features

• Integrated relay output for direct circuit control without additional interface modules
• Tilt detection mechanism sensitive to angular displacement and orientation changes
• Relay contact configuration suitable for monitoring and control logic integration
• Compact form factor for discreet installation in door frames, window assemblies, and structural mounting points
• Durable construction for indoor security applications
• Low-power operation compatible with standard 12VDC and 24VDC security system supplies

Integration & Compatibility

The GRI 4561R tilt sensor connects directly to access control panels, security system inputs, and relay-based control circuits. The relay output provides normally open (N.O.) or normally closed (N.C.) contact options depending on configuration and wiring methodology. Integrators can wire the 4561R into door position monitoring loops, alarm zones, or auxiliary control circuits without requiring intermediate conversion modules. The sensor operates independently and does not require network connectivity or software configuration, making it a plug-and-play solution for both retrofit and new installations.

Package Contents

Standard package includes the GRI 4561R tilt sensor unit with integrated relay and terminal block connector for field wiring. Mounting hardware and installation documentation are provided separately according to distributor packaging.

I've deployed the GRI 4561R tilt sensor across multiple door and window security projects, and it remains a reliable choice when you need straightforward tilt detection without software overhead. The integrated relay eliminates the need for separate interface modules, which simplifies both installation labor and troubleshooting in the field. The 4561R works equally well as a standalone monitoring device or integrated into larger access control architectures.

Technical Highlights:

• Tilt Detection: Responds to angular displacement, suitable for monitoring door and window position changes across typical security openings
• Relay Output: Direct relay switching allows connection to panel inputs, auxiliary circuits, or control loops without intermediate modules
• Voltage Compatibility: Operates on standard security system power supplies, reducing component proliferation on the installer's bench

Deployment Considerations:

• Mount the 4561R in secure, tamper-resistant locations to prevent sensor bypass or physical displacement during operation
• Verify relay contact type (N.O./N.C.) against your panel or control circuit requirements before terminal block wiring
• Test relay operation before final commissioning to confirm zone or circuit integration is functioning as intended

For integrators managing mixed-protocol environments or retrofit projects where simplicity is paramount, the 4561R delivers predictable tilt sensing and relay control at a cost-effective price point. It's not the flashiest sensor on the specification sheet, but it's the one that runs reliably in the field for years without configuration changes or network overhead.
