Interlock system used in the laboratory environment so the environments in terms of temperature, pressure and pollution are quite different, so there is a hallway between the two environments that are separated by 2 to 3 door, indispensable for opening door 1 and going into the hallway, the door 2 must be close and vice versa, so by magnetic sensors, doors become smart and commands to the system controller (interlock) import and after analyzing the situation, the output command is issued to the electric lock.
Each door has one input and one output, which can be equipped with access control system or the exit key this matter is determined depending on the set sensitivity and user requests,in this environment, for inter lock two doors for each door there are an output command to electric lock and 3 input command for push buttons, magnetic sensor and access control system.
All system components, send commands to the interlock system, after analyzing the situation by interlock system, the appropriate output is issued.
This is the simplest model of an interlock system that can be extended according to user requirements, for example, with a red and green lights or monitor through authorized and unauthorized display or when the door is open , over set time the alarms system will be active , any other application by the user can implement.
Below, you can see the schematic picture of environmental conditions:
