1. Introduction CT2000 is a advanced keypad manufactured in Denmark. It can be used as stand alone keypad and as a part of a larger system. The keypad has the following features: • Easy to use. • Waterproof. • No mechanical switches - durable. • Precautions against code guessing: • The keypad blocks after 4 invalid codes for a period of up to 255 seonds. • 100 different user codes. • 1 Master Code and 1 Service Code. • All codes can be programmed with 1 to 8 digits.

2. Programming Programming of the keypad is done by changing the value of one or more of the 118 different positions. Each of the positions numbered 00 to 102 can contain a code con- sisting of 1 to 8 digits. The rest of the positions controls how the keypad works. Notice:The keypad is different from other keypads on the market. It has no mechanical keys, but is operated just by touching the keys. Pay special attention to the yellow LED. The LED flashes every time the keypad has registered that you have touched a key.
13 Programming positions to program the Master Code. Switching output function and/or time CT2000’s open collector output is factory set to provide a 0V DC from it on the po- sitions 110 - 122 programmed time (e.g. in 5 seconds). The open collector outputs functions is programmed in position 103 and is factory set to the value 1, which cor- responds to the above 0V DC whenever you enter the correct code on the keypad.

Blocking time in case of code guessing (0 - 255 seconds) LED’s functions and indications.
2.2 Master Code (100) The Master Code is a limited version of the Service Code. It is only authorized to change the values on positions 00 - 99. That means change user codes. The code can be used by the person that is taking care of the daily operation of the system. The Master Code has position 100, but it is empty when the keypad leaves the factory.
2.5 Output choice (103) The value on this position decides how the keypad reacts when typing a user code. Value: Function: (Not used) Output active timer time Inverted output (Not used) Rolling code, 4 digits Rolling kode, 4 digits, inverted output Rolling code, 6 digits Rolling code, 6 digits, inverted output (Not used)

Function 4 Rolling code, 4 digits. Function 4, select a option where the keypad accepts a 4 digit code without subsequent use of the < # >. The code is ap- proved, so even though it is in the middle in a longer entry se- quence. Is the correct code example in 1234 and entered the 347123487, approves the code.
Function 9 Ask for output status. Function 9 will by entering a code followed by < # > show sta- tus at the output of a number of seconds, after which indication is turned off. The number of seconds can be set from 1 - 30 from position 122. During the status display, it is possible to change the status by typing the <...
2. LED’s (106) It is possible to control how the 3 LED’s on the top of the keypad should react in your specific installation. Standby refers to which LED that will illuminate when the keypad is in standby mode and ready to be keyed on (yellow LED is the default value). Aktiveret refers to which LED that will illuminate when the keypad is activated when typing on it (green LED flashes when typing a correct user code).
2.9 Reset By connecting the supply voltage, key in the Service Code (within 10 seconds), followed by < # >, < 250 > and < # >, returns the CT2000 back to factory default as described in section 2 page 4.

3. Mechanical mounting CT2000 must be mounted on a proper surface. By means of the included drill gauge, the holes for the four screws and the hole for the mounting cable are marked. If the surface is not completely proper, avoid twist or bending the keypad while mounting! Figure 3 shows the mounting, as side view.
4. Electrical connection The keypad CT2000 has 4 meters of 8/12 core cable mounted. The following shows how the keypad is to be connected CT2000 keypad 2 pcs. Ø4 mm. for 2,9 mm. screws 2 pcs. Ø4 mm. for 2,9 mm. screws...

5. RS485 Communication The whole 2000 system, inclusive CT2000 us the RS485 communication between the various units. RS485 If the various units in the 2000 system each have their 12V DC power supply (230V AC connected to different phases), there may be a larger voltage difference between the devices, and RS485 circuits can be destroyed. To prevent this, it is nessesary to make sure that the devices have the same potential.
5.2 Wired method When the devices are connected physically, it must be like pearls on string (see draw- ing below). Box 485-T PCI2000/ LogBox3 Box 485-T Prox Star connections must under no circumstances be used. If this is the case with the 2000 system, the T connection are used, the T assembly must be as short as possible.

The power supply can freely be placed as it fits in the installation.
7. Installation of PC Interface 7.1 PCI2000 PCI2000 is a communication interface between a computer and one or more of the following products: • CT2000 keypad and PR2000 proximity reader. • Box 485-T and Box 485-4 PCI2000 can be used to program the 2000 system, and to scan the installation of con- nected devices.
