Videx 4901 (replaces 4800) Keypad

The 4901 and 4902 codelock modules are completely standalone while the 4903 can operate as a standalone codelock or be networked to the GSMPRO audio module via RS485 bus.� The 4901 codelock has 3 relays and allows for 3 codes (1 code per relay) while the 4902 codelock has 2 relays and allows for up to 1000 codes that can be assigned to one or both of the relays. The 4903 has 2 relays and allows for 2 codes (1 code per relay) when in standalone mode, however when connected via the RS485 bus to the GSMPRO audio module access codes can be expanded up to 400 permanent codes or 32 temporary codes that can be assigned to one or both of the relays. The keypads have dry relay contacts (CO, NO and NC) where each output can be programmed from 1-99 seconds or 00 for latching. They also feature two switched 0V push to exit inputs to activate relays 1 and 2 respectively. Codes can be between 4-8 digits in length and each keypad module incorporates blue backlit key buttons.
