Sure-Fi Inc.


Wireless Bridge, wiegand, 2 outputs, 50 mile range, 902-928MHz, 12VDC


The Sure-Fi DS004 Wiegand Bridge System consists of two units that are factory paired and ready to use out of the box with no configuration required. These units are the Controller Interface, Model DS004-CONTROLLER, and the Remote Interface, Model DS004-REMOTE. The system provides a wireless connection (bridge) from a remote location (door, gate, or relay device), to the controller location, such as an access control panel. The controller interface wires to the access control panel and communicates wirelessly to the remote interface, which is placed near any peripheral Wiegand device (card reader / keypad / receiver) and/or any relay/switch activated device).

Each DS004-BRIDGE System consists of one Wiegand channel, two relay outputs and two relay inputs for functions such as door monitor sensors/request to exit inputs or any other relay-controlled function. Each unit has two relay outputs that correspond with the two relay inputs from the paired unit. The relays can be used independently and exclusively, meaning that it is not necessary to use the Wiegand input to use the relays. The Sure-Fi App provides for configuration, diagnostics, and field firmware updates.
