Door Strike Door Strike
The power for the door strike is customer supplied and provides AC or DC
power for one of the door strike outputs. The controller converts an AC
supply to a DC output. The reverse is not true. An AC door strike will not
work with a DC power supply. The maximum supply for the AC or DC Input
Door Strike is not to exceed:
• 28 VAC \ 1 A max
• 30 VDC \ 1 A max
