Minimizing Forced Door Alarms On A High Traffic Door

Hello Frank:

I have seen a hinge or pivot door position switch work in this situation. The DPS is moved to the hinge side of the door, and because the leaves of the hinge are nearly flush when closed, the sensor is built to be much more precise. Here is one style: GRISK DPS, but other manufacturers offer a range to match the hinge or pivot type you're dealing with.

In lieu of changing contacts, I believe you can increase the latch time before sending an alarm, or increase the shunt dwell of the sensor, but the specifics depend on which EAC system you're using. In some cases, increasing this period will also extend the 'unlock/unlatch' period of the locking hardware which is not always a good result.
