So what do you do when you need a fail secure “DC” strike to buzz? Try this out!! The ROFU model #9000 Buzzer measures a small 1″ x .63″ x.57″ and it hides out nicely in the jamb, but whoever is wanting to enter the door they will hear the strike is energized for them! The buzzer is rated for 7-30VDC and has a great price!
Have an awesomer Day! ~J
