AAS / Security Brand 27-240 Edge E4 Door Controller
The Security Brands 27-240 Edge E4 is the controller-focused member of the Edge 27 Series. Instead of being an integrated keypad or card reader, it is a smart controller for access-control installations where external Wiegand readers, credential devices, or other inputs are connected to the Edge platform. This makes it useful on pedestrian doors, commercial gates, parking entries, restricted areas, warehouse doors, and multi-access openings where the installer wants flexible reader placement and app-managed user control. The controller supports Bluetooth administration through the Edge mobile platform and offers Wiegand inputs, event inputs, digital inputs, schedule features, reporting, and programmable access behavior. It should be matched to the exact door hardware, gate operator input, lock power arrangement, reader format, and relay logic. Do not substitute it for an integrated keypad or reader unless the job includes the correct external access devices.

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
What is the difference between Edge E4 and Edge E1?
The Edge E4 is a smart controller for use with external readers or devices. The Edge E1 is an integrated keypad unit.
Does the 27-240 include a card reader?
No. The Edge E4 is a controller. External Wiegand readers or access devices must be selected for the installation.
Can this controller operate a gate and a pedestrian door?
It may control up to 2 openings when the wiring, outputs, and programming are set up for that application.
Can I use HID or SecurePass readers with this controller?
Compatible Wiegand readers can be used when the credential format and programming are correct. Verify reader output, power, and facility-code setup.
Should this be installed by an access-control technician?
Yes. Door locks, maglocks, gate operators, and Wiegand readers require proper low-voltage wiring and safe relay logic. A qualified technician should handle the installation.
