For fire and safety reasons, and per building code compliance in many jurisdictionsareas, a Request to Exit (REX) device is used required to ensure free unrestricted egress. It is always important essential to defer to consult the Authority Having Jurisdiction (AHJ) for all relevant building code requirements, including code requirements for those related to REX devices and how they should connect to an access control system, such as their integration with access control systems like Avigilon Alta. Although you can
While it's possible to wire a REX directly to the Avigilon Alta (formerly Openpath) ACU like , as with most other access control systems, the recommended best practice would be is to wire the REX in series with a maglock or other fail-safe hardware. This prevents any approach ensures there are no points of failure in the egress path.
If the REX device is wired connected directly to the REX input on an the ACU, then Avigilon Alta can simply either shunt forced-open alarms only, or both shunt forced open alarms and also trigger the relay to unlock. In the event that there is of a complete power loss, then the lock hardware specified by the AHJ would be Authority Having Jurisdiction (AHJ) will determine whether the system defaults to a Fail-Safe or Fail-Secure state.
Fail-Safe - When power is lost, the door will result in an unsecured position (unlocked).
Fail-Secure - When power is lost, the door will result in a secured position (locked).
