## Questions & Answers

**Q: Does this lock work with the Mighty Mule FM-200 Gate Opener?**
A: Yes it does.  Simply hook it up to the lock+ and lock- on the control board.  Disregard the additional circuit boards that are included.

**Q: Will I have to have a positive stop installed on my slave gate to make the gate lock work on my dual gates?i can take most of the play out of the gate**
A: Yes

**Q: Can this be used with smart devices?**
A: This lock is activated through the circuit board of the primary gate opener arm.  If you have a gate opener that can be used with smart devices, this lock can be also.

**Q: Will this lock work with FM350 gate opener?**
A: The answer is Yes and No, please let me explain. Yes it will work with the FM350 but if you have a lightweight gate it may be impossible for it to latch regularly. This lock requires approximately 10lbs. of force to latch. There are other gate locks that better handle the slow speed and relative low force of the FM350. Try the Estate Swing automatic gate lock, available on Amazon, it requires only 1/2Lb. of force to latch and is great for both low mass gates and slower speed gates.
