Conventional Mode or Conventional DHA Device
To activate the conventional mode, with the jumper removed, enter the address 0 in the dip switch.
Insert the battery jumper.
The Green and Red LEDs start to flash simultaneously.
Connect the DHA to 24V on the (LOOP in) plug. After this step, the DHA will report the status of the door and battery charge through the LEDs
indicated in the table below.
If by order of a conventional panel or other device the 24V fails, the DHA will release the door in a maximum time of 3 seconds.
At the insistence to re-open the door and dock at the DHA it will continually release it within three seconds.
After the 24V failure the DHA will monitor the door, but if there is no activity to dock it back to the DHA, it will go into sleep mode after 30 minutes
to protect the battery charge. The DHA will wake up automatically after the 24V returns to the system.
The DHA, after the port is docked, monitors its status every 100 seconds, if for any reason the door is released without an order from the release
button, the DHA will, in the case of the conventional system, return information that the door is released in the LEDs status.
