Reno H1-12-F Single Channel Loop Detector

Vehicle Detection Loop Module for Gate & Access Systems

The Reno A&E H1-12-F is a compact, full-featured, single-channel vehicle loop detector engineered for precision detection in automatic gate, barrier, and access control systems. Designed as a direct replacement for the legacy H-12-F model, it offers enhanced performance while maintaining plug-in compatibility. With selectable fail-safe or fail-secure modes, adjustable sensitivity, and a built-in detect memory function, the H1-12-F ensures reliable operation across a wide range of commercial and industrial environments.

Key Features

• Voltage Input: Operates on 12 VDC power
• Output Configuration: 3 solid-state (FET) outputs - Presence A, Configurable B, and Fail
• Fail Modes: Selectable fail-safe or fail-secure operation for Output A
• Detection Memory: Maintains detect state during momentary power loss (up to 2 seconds)
• Sensitivity Settings: 8 user-selectable levels with Sensitivity Boost option for high-bed vehicles
• Timing Controls: Selectable delay and extend intervals (0, 2, 5, 10 seconds)
• Loop Frequency: Four DIP-switch selectable frequencies to prevent cross-talk
• LED Indicators: Detect and Fail LEDs provide visual feedback and diagnostics
• Self Tuning: Auto-calibrates upon power-up or reset for optimal performance
• Compatibility: Direct plug-in replacement for H-12-F detectors
