Early Warning Detection

Easy Add-On
• The EWD was designed to enhance protection provided by the Horton 9100AP Revolving Door Series as well as the Secure Exit Lane.
• The system is to be mounted across the corridor, 7' above the floor, spanning the entire corridor.
• Traffic exiting the revolving door must be contained in the corridor, which must be between 3'4" and 10'0" wide. If existing structure does not provide a corridor, side lites can be added to create proper environment.

Superior Sensing Capabilities
The EWD uses an array of sensors working in harmony to provide a more robust security solution than any other detection system.
• Early Warning Sensor is for one-way traffic detection toward the restricted side of the door.  An additional sensor is mounted on the opposite side of the mounting tube to disable the Early Warning Sensor while normal traffic is exiting the door.
• Lockdown Sensor is an exclusive Horton People Counting Sensor which reliably discriminates between normal exiting traffic and unauthorized traffic attempting to approach the restricted side of the revolving door. When a pedestrian is detected traveling in the unauthorized direction, this sensor initiates an immediate lockdown of the door.
• Intelligent Interface Module integrates the Early Warning and Lockdown Sensors with the revolving door’s master control and locking system to ensure accurate warning and lockdown signals.
