🧠 The Concept

Unlike standard doors that need constant power (Maglock) or a continuous trigger (Strike), Turnstiles usually only need a short Momentary Pulse (0.5 - 1 second) to allow one rotation.

🛠️ Hands-on Steps

1. Volt-Free Contact: Most turnstiles provide their own power. You must use a "Dry Contact" (Volt-Free) relay from the Inner Range controller.
2. Pulse Time: In Integriti software, set the "Door Unlock Time" to 1 second.
3. Rotation Feedback: High-end turnstiles have a "Rotation Complete" switch. Wire this back to an input to accurately count users entering.
