No Door Core Drilling

SDC’s WPT’s RF technology sends power wirelessly across the door gap and allows for transfer of latchbolt monitoring, REX or data signals. WPT is perfect for powering, monitoring, controlling or communicating with failsecure electrified cylindrical locksets like our Electra™ 7200 series solenoid controlled cylindrical locks. These code compliant electric cylindrical locksets stay latched even when unlocked, maintaining fire door integrity.

From costly damage because of collisions to potential injuries, ensuring the safe operation of automatic swing doors is crucial for business owners and facility managers. What if there was a smart accessory designed specifically to mitigate these risks?
