K1 Series Keypad with Encoded Relay Module

The K1 Series is the next generation Keypad Keyless Entry system designed to provide a migration path from a multiple user stand alone access control system to an OEM compatible Keypad Reader. This design allows you to start with the K1 Series Stand Alone System for 1 to 3 door operation and reconfigure the Keypad in the future to add additional doors with a larger system. In stand alone mode, up to 500 user codes can be programmed into the K1 Series and each user code can be assigned to activate one of the three programmable outputs. This system is capable of being programmed either through the Keypad or through the Encoded Relay Module serial communication to a PC. User friendly software is included to simplify system configuration and User Programming. When connected to a PC, User activity can be logged and printed. As a secured system, the K1 Series Keypad with Encoded Relay Module provides an enhanced level of security by storing relays in a separate control module. All user programming and system configuration can be performed through the Keypad or optional PC Programming software (included with the Encoded Relay Module).
