This system is designed for controlling movement through a set of doors.  Each door requires a key to open.

4 key switches are used with this system.  One switch is used on each side of each door.

Typical Operation: A person approaching the Man Trap area must use their key to unlock Door #1.  Turning the key signals the power supply to unlock Door #1.  It also signals the power supply to "shut out" Door #2.  No one may use Door #2 until the first door is closed and locked.

Once Door #1 is locked again, the power supply is back in "standard" mode.  That is, both doors are locked and either may be opened by using a key.

The person will then use their key to unlock Door #2, which causes the power supply to simultaneously "shut out" Door #1.  This ensures only one door opens at a time.

The key to this system is the intelligent mag lock.  It contains built-in sensors to monitor the status of the door.  First, the armature plate used with each mag lock is specifically coded so it only works with that particular mag lock.  This prevents someone from tricking the mag lock into thinking the door is closed by presenting a metal plate to the lock.  The code must match before the mag lock signals the power supply a positive contact has occured.

Secondly, the mag lock contains a sensor that signals when the armature plate and mag lock have a strong bond.  It's not enough that the door is closed, it must be securely locked as well.  This is called a "bond sensor".  Only when a stong bond occurs between the lock and plate will the sensor signal the door is locked.

The power supply is constantly "communicating" with the mag locks.  Only when both have a strong bond with their coded plates will the system be in "standard" mode.  And standard mode is having both doors securely locked.
