Door Control Unit User Manual
Updated until firmware 404p - 36 -
For the Card Readers, there is no problem. You use 18 AWG according to the Wiegand
Standard. The communication distance is more than 100 Meters.
For the Door Lock, we estimate that if the load of 320mA is connected to a 16 AWG, at
122 Meters plus the 24 AWG 2 at meters the total voltage drop is only 4.73%. So this
should be fine for the door locks.
Our engineer did want to highlight some key issues and instructions you should follow for
the installation.
When using a strike type door lock. Please put the diode close to the door lock and make
sure that it is connected to the correct polarity. This type of door lock generates a large
amount of EMI.
As you want to connect a door lock directly to the DCU over your converter, by wiring
with only two 16 AWG Cables, you will lose other signals such as door status.
Please see the chart on the following page.
You will need to wire 16 AWG to PIN's 4 and 8. In addition to this you will need to short PIN 2 to
PIN 8 to disable the tamper alarm.
This concludes the DCU user manual.
Please contact support@akcp.com if you have any further technical questions or problems setting up your
modem or your alerts.
