DK2850 is a Dual Relay, Vandal Resistant, Weatherproof full-feature Access Control keypad system. The DK2850 key buttons are metal and Back-Lit. The metal housing is rugged specially designed to sustain the punishment and abuse of high traffic and a harsh environment. It has 2 relay output each controlled by 2 groups of independent User Codes. Output 1 is a 5 Amp rating relay providing both N.C. and N.O. dry contacts for electric strike or magnetic locks, Output 2 is a 1 Amp rating relay also providing N.C. and N.O. dry contacts for other control applications, such as controlling an alarm system. Three LED lamps are wired internally to indicate the operation status of the outputs 1 and 2 and the system status of the keypad. For easy wiring the keypad utilizes a terminal block for external connections. The DK2850 dimensions fit the size of an electric single gang box. It can be surface mounted with its aluminum housing or flush mounting on the wall.
