AAS / Security Brand 27-220SK Edge E2 SK Card Reader
The Security Brands 27-220SK Edge E2 is a Secura Key proximity-reader version of the Edge E2 smart card reader. It is intended for installations where the access-control credentials are Secura Key style, while the controller and programming side remain part of the Security Brands Edge 27 Series. For a technician, the critical difference is not the enclosure alone; it is the reader technology inside the unit. A 27-220SK should not be swapped with a 27-220 SecurePass or 27-220HID reader unless the customer is also changing credential systems and reprogramming users. Security Brands lists the 27-220SK as discontinued and points customers toward the Edge E2 SecurePass version, so this row should be handled as a legacy or replacement listing where credential compatibility and availability must be verified. It is commonly associated with gate pedestals, pedestrian access points, and commercial access-control installations that used Secura Key credentials.

Technician Note
Match this product by the model number, receiver or credential format, wiring method, and the gate operator or access-control input being used. Similar Security Brands products can look alike but use different radio frequencies, reader formats, controller functions, or included components.
Before Ordering Checklist
- Confirm the manufacturer part number on the existing product or system documentation.
- Verify power requirements, receiver or reader format, and relay/input wiring.
- Confirm whether the product is a complete kit or only one piece of the system.
- Check mounting style, enclosure, pedestal, and environmental exposure.
- For gate operators, keep required safety devices in place and do not bypass monitored protection devices.
Professional Advisory
Access-control wiring, gate operator inputs, magnetic locks, door strikes, and detector outputs should be handled by a qualified gate or access-control technician when the installation is not a simple like-for-like replacement. High-voltage work and unsafe gate movement should be corrected before the access device is placed back into service.
Product Questions and Answers
Is the 27-220SK still a current Security Brands item?
Security Brands references identify the Edge E2 SK version as discontinued, so availability and replacement direction should be checked before ordering.
What makes the 27-220SK different from the 27-220?
The 27-220SK uses a Secura Key proximity reader, while the 27-220 SecurePass version uses the Security Brands SecurePass reader.
Can I replace a 27-220SK with a 27-220HID?
Not as a simple swap. HID and Secura Key credentials are different, so the reader, credentials, and programming must be planned together.
Does this still work with Edge programming features?
Yes. The 27-220SK belongs to the Edge E2 family and supports Edge-style programming and app-based management when used in a compatible setup.
What should I check on an existing installation?
Check the label, credential type, facility code, power, Wiegand wiring, relay wiring, and whether the site is keeping Secura Key credentials or converting to another format.
