Single Relay Output Digital Access Control Keypad

DK-9821 is a full feature keypad with single relay output mainly designed for those installations requiring electric door strike and having door open/close monitoring. The 5 Amp output relay provides both N.C. and N.O. dry contacts for door strike, which is virtually compatible with any electric locking devices. The keypad works perfectly in both stand-alone electric lock and inter-lock door striling systems. Four LED lamps are wired internally to indicate its operation and system status. The keypad utilizes terminal block for all the external connections.
