6.5 NIGHTLIGHT FUNCTION

When this function is selected, the act of touching any key will operate the programmable relay for five seconds. This may be used to turn on a lamp directed at the Keypad at night so that the person using the Keypad can see to enter the code. Put the unit into program mode and enter 7-7. You will see the two flash confirmation. Then, exit program mode. Note that selection of this option means you give up the opportunity to implement a doorbell or other use of the programmable relay.

To return the programmable relay to factory set (doorbell) function, put the unit into program mode and enter 7-8. You will see the two flash confirmation. Then, exit program mode.

7. ADDITIONAL HARD WIRED OPTIONS

7.1 DUAL PAD OPERATION

If keypad control from both sides of the door is desired, two keypads can be connected to one CPU Board. Simply put the colored wires from both keypads into the appropriate terminals on the CPU Board such that 2 wires are in each terminal. Either keypad will then be able to release the lock and both keypads will beep and illuminate their LED's when either one is used. Two is the maximum number of keypads that can be connected to one CPU Board. Note that in the unusual case where both keypads are being used simultaneously, the door will not release as the sequence will certainly be disturbed. Only one keypad may be used at a time. Be sure you don’t violate egress building codes when employing a keypad on the inside of a door. Check with your local building or fire department.

7.2 HARDWIRED CODE DISABLING

This means making a switch connection to the CPU board which will cause valid codes to not be accepted. The DK-26 has two terminals marked “HCD” and “UCD” which will respectively disable the Hard code and all User codes. Simply connect the SRC terminal to either of these terminals via an external switch and the respective codes will not function while the switch is closed. Alternately if you supply +12V or +24V from the DC+ terminal to either of these terminals, it will have the same effect.

The main reason for doing this is to support

day/night operations. For example, you could

 

allow all User codes to be active during the day

 

 

 

 

but disable them at night by closing a switch

 

 

 

WITH THE CONTACTS

between SRC and UCD. The Hard code would

could have no Hard code programmed so that

such as Securitron’s model DT-7. It’s finally

 

 

 

 

possible to flip the codes (Hard and all User) so that, for example, User codes are active only during the day and the Hard code is active only at night. An SPDT switch or relay is needed to do this as the drawing to the right shows. Note that you won’t be able to use one of these disabling features (Hard or User) if you have implemented the door prop alarm (Section 6.4) or anti-tailgating (Section 7.4) features. These reassign one of the terminals.
