 |
| Door closed and interlocked | Requires power:
voltage is applied to the coil to activate
interlock; quicker access possible in the event of a
power loss or wire breakage. Both the N.C. enabling contact 21-22 and the N.C. door monitoring 11-12 contact are closed |
|
| To release door (deactivate interlock) | Remove voltage from the coil (A1, A2), e.g. from a motion detector. The N.C. enabling contact 21-22 opens. The N.C. monitoring contact 11-12 remains closed as long as the door remains closed. | |
| Opening the door | Only possible once door is released (interlock deactivated). The N.C. monitoring contact 11-12 opens to indicate the open door. | |
| Door Open | Both contacts are
blocked open, even where attempts are made to tamper using basic tools. |
|
| Re-closing the door | Triple-coded
actuator removes the block on the N.C. enabling contact 21-22. The N.C. door monitoring contact 11- 12 re-closes. |
|
| To interlock door | Reapply voltage to
coil: 1. Actuator is locked in. 2. The N.C. enabling contact 21-22 closes. The enabling contact can only close when the door is interlocked. |
