Inovonics EN1215WEOL Transmitter with Wall Tamper & Reed

Inovonics EN1215WEOL Wireless Transmitter with Wall Tamper & Reed Switch

Overview

The Inovonics EN1215WEOL is a wireless transmitter designed for security and access control integration in distributed monitoring systems. This unit combines wall tamper detection with a reed switch contact sensor, enabling dual-function monitoring across entry points, window openings, and secured enclosures. Operating in the 902-928 MHz frequency band, the EN1215WEOL delivers reliable wireless communication for integration into Inovonics-based security networks and compatible third-party platforms that support this transmission protocol.

Key Features

• Wireless Transmission: 902-928 MHz frequency band for reliable communication without hardwired connections
• Wall Tamper Detection: Built-in tamper switch detects unauthorized removal or displacement from mounting surface
• Reed Switch Sensor: Integrated reed contact for detection of door, window, or enclosure opening
• Dual-Function Monitoring: Simultaneous wall tamper and reed switch reporting within a single device footprint
• Extended Temperature Range: Operates reliably from 32°F to 140°F (-0°C to 60°C), suitable for interior and temperature-controlled environments
• Wireless Protocol Compatibility: Designed for integration with Inovonics security systems and compatible wireless monitoring platforms

Integration & Compatibility

The EN1215WEOL transmitter integrates into wireless security networks that support the 902-928 MHz ISM band. This frequency selection ensures operation within commonly allocated spectrum for security and industrial applications. The dual sensor design—wall tamper and reed switch—allows a single unit to monitor both device integrity and entry point status, reducing installation footprint and simplifying system configuration. Typical integration scenarios include perimeter protection, secured equipment enclosures, and access control point monitoring where both physical tampering and door/window state must be reported to a central monitoring system.

Technical Specifications

The EN1215WEOL operates across an extended temperature range from 32°F to 140°F, ensuring performance in climate-controlled indoor spaces. Its wireless architecture eliminates the need for hardwired connections to monitoring equipment, reducing installation complexity and enabling flexible placement. The combination of wall tamper and reed switch sensors within a single transmitter provides comprehensive breach detection—alerting to both unauthorized device tampering and actual entry point compromise.

I've specified the Inovonics EN1215WEOL in several distributed security deployments where both device-level tamper protection and entry point monitoring are required. The dual-sensor configuration—wall tamper combined with reed switch—eliminates the need for separate transmitters at single locations, which simplifies deployment planning and reduces cost per monitored point.

Technical Highlights:

• 902-928 MHz Operation: Operates in a frequency band commonly allocated for security systems, reducing interference concerns and supporting coexistence with other wireless security devices on the same network
• Wall Tamper Detection: Alerts the system immediately if the EN1215WEOL is removed, displaced, or tampered with, adding a layer of system integrity assurance
• Reed Switch Contact Sensing: Provides reliable detection of door or window open/close events without requiring external magnetic contact assemblies

Deployment Considerations:

• Verify receiver/hub compatibility with the EN1215WEOL's transmission protocol before deployment to ensure seamless integration
• Position the transmitter within the effective RF range of your monitoring hub, accounting for walls, metal structures, and environmental RF noise
• Ensure the operating environment remains within the specified 32°F to 140°F range to maintain reliable sensor responsiveness

For security integrators building multi-sensor perimeter systems or access control networks, the EN1215WEOL delivers straightforward dual-function monitoring in a compact form factor. The combination of tamper and reed detection in a single wireless transmitter reduces component count and integration complexity without sacrificing sensor capability.
