Why is Electrodyn introducing a new type of door restrictor?
To date, manufacturers have explored two approaches to door restrictor design—mechanical and electromagnetic. The first type, mechanical door restrictors, are problematic because they tend to be noisy and are difficult to align and repair. The second type, electromagnetic door restrictors, use photoelectric sensors instead of metal-to-metal contact. However, calibrating the electric eyes and target strips used by these devices is time-consuming, and the functionality of these systems is degraded in the presence of dust, smoke, grime, and ambient light. Both types of door restrictors are subject to failure in an unsafe position. ElectroLock™ was designed to address all known problems with mechanical and electromagnetic door restrictors, even to the point that should the system fail for any reason, it will fail in the safe position.
