WHAT ARE THEY?
Electronic interlock systems control two or more doors such that if one door is open the remaining doors will only open if pre determined so. For example a simple 2 door airlock could be constructed so that Door A will only open if Door B is closed and secure.
HOW DO THEY WORK?
Each door is electrically locked and monitored. The control electronics then generates a control signal to indicate when the door is closed and secure. Each controller also has a control input that will prevent the releasing of the locking device. In this way the door controllers communicate the door status and only open when it is safe to do so.
HOW MANY DOORS CAN BE INTERLOCKED?
The simplest interlock would be with 2 doors and standard systems can be made up to 4 doors. Larger systems can be made and even overlapped.
HOW IS AN INTERLOCKED DOOR OPENED?
This can range from a simple push button or passive RQE detector to a full blown access control reader. All the Progeny P1 controllers have interlocking interfaces as standard. This means you can mix interlock controllers with access controllers on the same system.
These units provide all the electronics to control and monitor a door and provide interlock with another door or access control unit. Trigger inputs drive a lock timer that can be adjusted from 3 to 40 seconds. Door monitoring allows door forced and prolonged door open alarms to be generated.
2089 Interlock Controller
2089D Interlock Controller 2 Door
Note the current limit of the mains derived supply is 2.0 amps at either the 12 or 24V
setting. However 0.5 amps of this should be reserved for charging the batteries and
running internal electronics. This leaves 1.5 Amp DC for externally connected loads.
2069 4 Way Interlock Programming Module
For use with any combination of P1 controller and or interlock controller (2089’s, 2063’s, 2163’s). Allows easy and flexible programming of interlock systems. Greatly simplifies wiring and system debugging. This unit takes its supply from the other controllers. A 12 way DIP switch allows the interlocking to be programmed in any combination. On board indicators show current interlock signal status.
