Automatic Door Locking System

Description and Purpose

In banks, cash payment centers, and other public processing offices, it can be difficult to control unplanned overtime due to sudden increases in clientele at the end of the business day.

Often, a clerical worker closes a station, and locks all the entry doors to stop the inflow of traffic. The clerk then stands at a door designated as an exit, and unlocks the door to allow individuals who have completed their business to leave.

The automatic door locking system allows all stations to remain active so processing can continue.  It can automatically lock all entry doors so that no new clients may enter, while allowing those who have completed their business to exit by pressing an exit bar, which temporarily kills power to the magnetic lock. This creates an automatic emptying effect that clears the lobby at the end of the day. The system can also switch on the “Closed” sign, if needed.

Automatic door locks can integrate with the fire alarm, intrusion, or panic system so that in the event of a crisis, the system can lock doors to stop entry of newcomers. In addition, the system can integrate door position sensors to verify the closed status of the door while locked. The maximum number of doors that can be locked by the system depends on the control panel you choose.
