Electric latch rune missing reset?

[Tamago]

Looking at the stat block for the Electric Latch Rune in the Playtestiary, I don't see an indication of the trap's reset time. Is this a one-and-done thing, or does it happen every time someone tries to open the door? Or does it need time to recharge?

This makes a significant difference for parties who lack a rogue (or whose Thievery-based character is rolling poorly).

Seems like a one time use in the corebook although in the Campaign it would seems odd for a Wizard that wish to protect his tomb forever to use something that would work only once.
