The DK-26 operates a 5 Amp DPDT relay to switch any type of fail-safe or fail-secure electric lock (or strike). Release time is programmable from 1-99 seconds.
A beeper and three LEDs provide feedback during operation and programming. Power for the DK-26 is 12 to 24 volts, AC or DC.
Typically, the same power source is used to operate the lock, which makes planning the installation simplicity itself. You can even employ an inexpensive AC transformer to operate a DC lock, as the DK-26 will convert AC to DC and supply it to lock.
