DRB-IR-K4 Infrared Touch Free Exit Button

The DRB-IR-K4 Touchless Infra-Red Exit Button is a surface mounted request-to-exit device designed for access control and electronic locking systems. Using infra-red detection, the unit allows users to activate the door release without physically touching the button, making it suitable for busy commercial, public and professional environments.

Manufactured from ABS fireproof plastic, the DRB-IR-K4 operates from 12-24VDC or 12-28VAC and provides NO / NC / COM changeover contacts for connection to compatible access control and electric locking equipment. The contact rating is 3A at 120VAC / 30VDC.

The unit features an adjustable infra-red detection range of approximately 5cm to 20cm and an adjustable time delay from 0.3 to 30 seconds. The LED is red in standby and changes to green when the sensor is triggered.
