Description of function
The code number keypads are code switching devices which accept up to 5 different open codes.
Each code activates the same potential-free relay output. Via the keypad,
up to 5 code numbers, each a maximum of 6 digits, are entered with a master code. Once the data has been entered, it
will remain stored, even in the case of a power failure.
Subsequent to entering the valid open code and pressing the key with the bell symbol,
the green LED lights up on the keypad and the relay is activated for approx. 2 seconds.
If the red LED lights up during the code entry an incorrect code has been entered.
The red LED goes out after a few seconds. Only then can a new code be entered. If an incorrect code has been
entered 5 consecutive times, the keypad blocks for one minute.
CTI, CTI B
The device only consists of the keypad.
CTS V, CTS BV
The device consists of 2 parts: The keypad and the decoder. The keypad and the decoder are in sync as a pair with
one key number.
Only keypads and decoders with the same key number can work together.
Programming the Devices
1 Programming a new open code
1.1
Press the key “P”.
The red LED starts to blink.
1.2
Enter the valid master code
(see also “Master Code Factory Setting”).
1.3
Press the key with the bell symbol.
The green LED starts to blink, the red one goes out. (If the red LED is
continuously lit up or continues to blink and the green LED does not blink, the entered master code was
incorrect. Wait until no LED is lit up and try again.)
1.4
Enter the new open code
1.5
Enter the number of the storage location (1 – 5) where you want to store the open code.
1.6
Press the key with the bell symbol.
The green LED goes out and the new open code is now saved under the
selected number.
Important!
Since the number of digits of the open code which is saved under storage location no. 1 defines the number of valid
digits of the open codes which are saved under the storage locations no. 2 – 5, it must be entered first.
The number of digits of the open code which is saved under storage location no. 1 must be the same for the other
open codes.
Example: You want to save open code 4711 under the storage location no. 2:
Enter the digit sequence: 4711 2
If an open code which has been saved under a certain storage location is to be made invalid the corresponding
storage location must be overwritten with the new open code.
