TROUBLESHOOTING LOCK CONTROL
The DS2 Dry Contact Relays are 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 ** is pressed on the attached telephone.
Lock Power should connect to Brown and Orange 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 DS2 unit or the relay within the DS2
unit itself.
If possible, please bypass the connection box and the RJ to RJ lead
connecting to the DS2 unit by feeding the two power supply wires of the
electric lock into an RJ45 plug in positions 2 & 7
.
If the lock then works with **, then the problem is in the connection box or the
RJ to RJ lead connecting to the DS2 unit.
If the lock still does not work with **, then the problem may be within the DS2
unit, or interference is preventing DS2 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 DS2.
If your problem is still unresolved, please call Natcomm on ph 800 530 8645 to
report the above results and arrange for further advise or repair.
IMPORTANT NOTE - You must not use the Power Adaptor supplied with
DS2 to power either Door Lock or Strike.
