Videx 4903/BL backlit GSM keypad module, 500 codes & 2 relays - gun metal grey finish

ADDITIONAL INFORMATION

4000 Series Codelock Modules

There are three optional codelocks available: the 4901 codelock module which is completely standalone, the 4902 and 4903 that can both operate as a standalone codelock or be networked via an RS485 bus for GSM audio intercoms. 

The 4903 can be networked with the GSMPRO (4810) audio module (as well as other 4903 keypads and 4850R proximity readers).

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 (for the 4901 and 4903) or set to 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.

Each codelock is available in a mirror stainless steel finish, a matt 316 grade stainless steel finish (suffix /M) or a gun metal grey finish (suffix /BL).
