How do Alarm.com card and keyfob credentials work?
Format
The following table includes Alarm.com card and keyfob credential models with their corresponding format and facility codes.
Note: The Alarm.com 46-bit format is only compatible with Alarm.com readers. When using this format on Alarm.com systems, the facility code should be ignored.
| Card model | Card format |
|---|---|
| ADC-AC-CARD-50D4 | Alarm.com 46-bit (Facility Code 0) is used with an Alarm.com reader. Alarm.com 36-bit (Facility Code 7) is used specifically when paired with a non-Alarm.com Prox reader. |
| ADC-AC-CARD-50H4 | Alarm.com 46-bit (Facility Code 0) |
| ADC-AC-FOB-60H8 | Alarm.com 46-bit (Facility Code 0) |
Note: Alarm.com card credentials are marked for vertical or horizontal slot punches. The cards may be punched on the dotted line.
Ordering
When ordering the ADC-AC-CARD-50D4, ADC-AC-CARD-50H4, or ADC-AC-FOB-60H8 credentials, there will not be an option to select a card range or facility code. This is due to each credential produced using a unique card ID number and no duplicates are made.
