Allegion Integration

Keyless access. Made easy.

Protege integrates directly with the Allegion AD series of locks to provide a cost effective and scalable access control solution to meet your security needs - even where wiring won't reach. Integration is available in both hardwired (AD-300) and wireless (AD-400) configurations to suit your requirements. The locks feature a built-in credential reader and door control sensors for simplified installation.

The online controller level integration allows the locks to communicate with the Protege system in real time - giving you real time access control and event monitoring without the need for complex (and costly) wiring. Lock reader heads are available in 13.56MHz MIFARE/DESFire, 125kHz proximity, and magstripe, all with optional keypad. Locks are available in mortise, mortise deadbolt, cylindrical and exit trim chassis.

How it works

On site, the user presents their credentials to the lock that sends the relevant user information to the PIM module which in turn relays it to the Protege controller. The controller then makes a decision based on the configured access permissions and the result is sent back to the lock, and the user is granted or denied access in real time.

AD-300 Wired Locks

A multi-drop RS485 bus is used to connect the AD-300 series lock directly to the Protege Controller. Up to 32 locks may be connected to a single reader port on the controller, allowing up to 64 AD-300 locks per controller.

AD-400 Wireless Locks

The wireless locks communicate via 900MHz frequency to a Panel Interface Module (PIM) which is connected to the Protege controller via RS-485. The 900MHz band enables longer transmission ranges as wavelengths are able to travel a greater distance and better penetrate typical building construction – allowing for simplified system design. As 900MHz operates on a different frequency to WiFi, it won’t burden existing IT infrastructure. Up to 128 locks may be connected to a single Protege controller.
