The Security Brands 25-K2 Ascent K2 Cellular Keypad with Proximity Reader Mount is a cellular keypad and access-control unit for compatible gate and door applications. It is powered by the Security Brands Summit Control platform and is designed for sites that need remote management without running a traditional telephone line to the entry point.
This version is configured with proximity card reader mount for a compatible reader selected separately. Confirm the exact model number before ordering because 25-K2, 25-K2SBI, 25-K2HID, and 25-K2SK are similar but not automatically interchangeable.
The Ascent K2 provides cloud-managed cellular access control for select gates and doors. Depending on the site setup, users may be granted access through app, text, voice, keypad, GuestPass QR codes, and compatible proximity-card reader methods.
The 25-K2 is the mount-only version. If the customer needs a preinstalled SecurePass, HID, or Secura Key reader, choose the matching 25-K2SBI, 25-K2HID, or 25-K2SK version where available. The installed reader, credential format, facility code, relay wiring, Wiegand wiring, cellular signal, and service plan must all match the project. Do not order by housing style alone.

Most K2 ordering mistakes come from reader mismatch. A SecurePass card, HID credential, and Secura Key credential are not the same just because they are all proximity cards. Match the reader and credential system before the unit is installed.
Install and wire this access-control system only in accordance with the gate operator, door hardware, and Security Brands instructions. Use a qualified low-voltage, gate, or access-control technician when relay wiring, Wiegand wiring, cellular setup, or safety-related circuits are unclear.
For South Florida and Hialeah Gardens area projects, confirm cellular signal at the pedestal or wall-mount location before scheduling the installation. Concrete walls, metal gates, equipment rooms, and dense landscaping can affect signal and service reliability.
The 25-K2 Ascent K2 is used for cellular gate or door access control where users may be managed through Summit Control and granted access by keypad, app, text, voice, QR code, and supported reader methods.
The reader configuration depends on this exact model. The 25-K2 has a reader mount only, while 25-K2SBI, 25-K2HID, and 25-K2SK are reader-specific versions. Confirm the model before ordering.
The Ascent K2 platform is commonly listed for control of up to two gates or doors when wired and configured correctly. Final control depends on relay wiring, gate or door hardware, and system setup.
No landline is normally required for Ascent cellular access control, but the site must have adequate cellular coverage and an active service plan through the supported platform.
Existing credentials work only if the reader type, credential frequency, facility code, and Wiegand format are compatible. Do not assume HID, SecurePass, and Secura Key credentials are interchangeable.
Check cellular signal, power, relay wiring, Wiegand wiring, reader type, credential format, enclosure location, gate safety devices, emergency access, and the Summit Control account or plan.
No. The keypad or access-control relay should never be used to bypass photo eyes, safety edges, fire access, emergency access, or gate operator safety circuits.
The Ascent platform is cloud and cellular based, so activation, cellular service, and plan limits should be confirmed before installation or account setup.
