Access Control and Intrusion _ Innovative. Reliable. Dynamic.

SECOR Request to Exit Button

DFM has designed and developed wide range of top quality request to exit button, from piezo button, vandal & weather proof mushroom button and touchless sensor to a large variety of mechanical switches.  

The piezo exit button WEL2451/2450 is uniquely designed and developed using Piezoelectric Effect technology. The switch can be activated by a finger touch without any physical movement, while a dual-colour LED or internal buzzer is used to indicate the button action. 

The heavy-duty vandal & weather proof mushroom button WEL2440 is designed to be install in an application where it is at risk of being subject to vandalism or tampering, as in the case of a public area or even prison. 

Touchless exit button WEL2261 and WEL3761 are uniquely designed for the application where sanitary condition is needed, like hospital, clean-room, food processing factory and laboratory. They also provide much easier access for the disabled to open doors through a sensor.

Custom wording on faceplate can be made on request for non-standard applications.
