McGrath RBH52 Standalone Access Control Keypad
The McGrath RBH52 is a fully standalone hardwired access control keypad with integrated fingerprint reader and built-in Wi-Fi. Designed for gates, electric strikes, magnetic locks, garage doors and automated entry systems, the RBH52 provides secure multi-method access control in a compact IP66 rated housing.
Unlike wireless accessory keypads, the RBH52 is a complete 12V DC powered controller with onboard relay output (NO/NC/COM). It supports fingerprint, PIN code, RFID credentials, Bluetooth eKeys and native Wi-Fi remote management through the McGrath Locks App. No separate gateway is required.

The RBH52 is a standalone access control keypad and controller. It is not a lock, and it is not a wireless accessory keypad. All PIN codes, fingerprints, RFID credentials, and Bluetooth users are stored internally within the device.
When a valid credential is presented, the RBH52 activates its internal relay (NO / NC / COM terminals) to control a connected device such as an electric strike, magnetic lock, gate motor, garage door, or automated door.
Because the relay output is built in, the RBH52 directly controls the locking hardware. It does not need to be paired to a separate smart lock to function.
Built-in 2.4GHz Wi-Fi allows remote management and monitoring through the McGrath Locks App. User enrolment, audit trails, schedules, and access permissions are all managed within the app without requiring an external gateway.
In simple terms:
- The RBH52 stores the users.
- The RBH52 validates the credential.
- The RBH52 triggers the relay.
- The connected lock or device physically opens.
