Hi all,

Something strange is going on with my new POPP Strike Lock.  
Schema:  
 ![Schema strikeLock and magnetic lock_2](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/a/2/a2e84af80197bb7b2f6b0e2c1bf0858f99361dba.png)  
When I press “Unlock” in Homey, I measure 12V between pin 1 & 5.  
When I press “Lock” in Homey, I measure 0V between pin 1 & 5.  
**Of this should be the other way around of course!** My Magnetic lock works (“locks”) when current is applied. And no, switching pin 1 & 5 doesn’t help.

See the following movie for some live action: [https://www.dropbox.com/s/27i58xisyzz9h2y/StrikeLock%20behaviour.mp4?dl=0](https://www.dropbox.com/s/27i58xisyzz9h2y/StrikeLock%20behaviour.mp4?dl=0)

Any idea(s) ?

Hi Roy,

The device is attached to a 230V AC to 12V DC transfo. So no battery drain risk.

The magnetic lock that I’m using requires power to be locked.

But changing 6 with 4 did the trick!

Many thanks for the quick reply and solution.
