Tongue Interlock - dual key (actuator/keys not included*)
2 sequential keys - 1 key trapped, 1 key free - actuator unlocked

The TD-11 has 2 sequential keys - one key trapped, one key free - actuator unlocked. When the actuator is unlocked the "access" key can be taken "on the person" into the guarded area without fear of the "trapped" key being removed and the equipment restarted.

The TD-11 Tongue Interlock works on the principle that when the "access" key is "trapped" the actuator cannot be removed and is locked in position. Only when the "free" key from the Isolator or Key Exchange System is inserted into the second barrel can the "access" key be removed thereby allowing the actuator to be removed.

Only when the isolator key is returned to the Isolator Switch can power then be re-applied to the guarded area.

Watch our video below to see how the key exchange system works . . .
