REX It Right
Motion sensors are used for Request To Exit functionality in electronic access control systems. The Request To Exit device sends a trigger to the electronic access control system to unlock the lock and also signals the control that the door is being unlocked to egress, rather than forced open in an unauthorized entry.
Without the REX device, the electronic access control system has no way of knowing whether the door opening is forced or a legal exit occurring.
How the electronic access control system handles the egress will vary between manufacturers, but there are typical characteristics of these systems. Of course it is up to the installer to verify how the particular system he uses needs to be wired and configured.
When the REX detects an egress, it sends a signal to the controller which then bypasses the door position sensor and triggers the internal door unlock timer in the controller. This shunting remains active for a preset time, or resets once the door position sensor senses that the door has been opened and reclosed. If the shunt times out and the door is still open, then the system may report a propped door alarm.
If the door is opened without either a valid card or PIN entered or the REX triggering first, the system interprets the door opening as a forced door.
A problem with REX motion sensors has been that they typically have a wide detection range. This is good for safety and the convenience of the users. But because if the wide pattern, REX motion sensors can be tricked by a variety of methods, thereby creating opportunity to gain entrance into the protected area.
The BEA R2E 100 Sensor has a controlled detection pattern designed to look only at the lock lever rather than the surrounding door floor and wall area, thereby reducing or eliminating the functional deficits suffered by traditional REX sensors.
The BEA R2E 100 has other features and signal processing capabilities to suit it for many access control applications.
The R2E-100 is mounted on or above a door header so that its detection pattern is placed precisely in front of the door handle. In this scenario, when the user reaches for the door handle to exit, the electronic locking (EL) device is released, and the person can exit.
The active infrared detection curtain of R2E-100 is well defined to keep the door secure, while rejecting parallel traffic and objects slid under the door. The detection distance, or range, of the sensor is adjustable from 20 to 48 inches.
The LCN 4040XP is the second generation heavy duty door closer designed to withstand even more rigorous applications.
