TROUBLESHOOTING LOCK CONTROL
Both
DS3
Relays are Dry Contact Relays rated at 12V/1A.
If you are having trouble controlling the LOCK or GATE STRIKE, please
trouble shoot by using the following procedure:
Test that you receive the correct voltage across the terminals of the supplied
connection adaptor, when ** or *2 is pressed on the attached telephone.
Lock 1 should connect to Brown and Orange terminals.
Lock 2 device should connect to Blue and White terminals.
If the correct voltages are not present investigate all wiring to and from your lock
and power source.
If the correct voltage is present, short across the two terminals and your electric
lock should operate.
If your lock still does not operate, there will be a problem with wiring between your
power supply, electric lock and connection box.
If your lock operates, then the problem is located in the wires of the connection
box, the RJ to RJ lead connecting to the
DS3
unit or the relay within the
DS3
unit
itself. If possible, please bypass the connection box and the RJ to RJ lead
connecting to the
DS3
unit by feeding the two power supply wires of the electric
lock into an RJ45 plug in positions 2 & 7 (Lock 1) and 1 & 8 (Lock 2)
.
If the lock then works with ** or *2, then the problem is in the connection box or the
RJ to RJ lead connecting to the
DS3
unit.
If the lock still does not work with **, then the problem may be within the
DS3
unit,
or interference is preventing
DS3
from detecting the ** command.
ADSL Interference or Electromagnetic Interference (EMI) caused by Switch
Mode Power Supplies or Uninterruptable Power Supplies can prevent the **
touch tones from being detected by
DS3
. Follow the instructions on page 20.
If your problem is still unresolved, please Email Natcomm at [email protected]
to report the above results and arrange for further advise or repair.
IMPORTANT NOTE - You must not use the Power Adaptor supplied with DS3
to power either Door Lock or Strike.
