Assembly hints 1. Assembly (Skipping this can lead to troubles ! ) Ok, so we have your attention. These hints will help you to make this project successful. Read them carefully. 1.1 Make sure you have the right tools: • A good quality soldering iron (25-40W) with a small tip. • Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to the tip, to give it a wet look. This is called ‘thinning’ and will protect the tip, and enables you to make good connections.

Construction This code lock can be used to switch an alarm (e.g. car alarm K3504) on and off as well as to open a door lock. A LED on the operation panel reflects the state of the "lock". You can easily determine the code yourself. Thanks to its reduced dimensions, this code lock is very well suited to be built into a standard housing. Its fully closed operation panel allows it to be used inside as well as outside.
The code Determining the code The four code digits are determined by fitting wire jumpers, see figure 1.0. Drawing 1.1 shows the connections for code 1234 as an example.
Preparation Preparation Fit seven non insulated wires at the solder side of the pcb. These wires will be used later on for through connection to the master module (see fig. 2.0). F Attention : the wires at the component side must be cut off as close to the pcb as possible.
Construction Construction of P6400B 1. Jumpers q J on/off function of the key lock. q J1 Fit wire jumper J1 in case you intend to use the on/off function of the key lock. If you don't fit this wire jumper, then, at the input of the code, the code lock will only generate a pulse (in general this mode is used with door locks). "closed" contact or "open" contact .

Assembly Assembly (fig 3.0) ! CHECK THE WHOLE MOUNTING ONCE MORE THOROUGHLY AND DON'T FORGET THE CODE, BECAUSE AFTER THE FOLLOWING ASSEMBLY IT WON'T BE ACCESSIBLE ANY MORE. Pass two 2mm bolts through the front panel and fix them using a nut. Then pass a lock washer over the bolts followed by the keyboard module. Take care that the LED is in the front panel. Normally, neither the LED nor the push buttons may pass through the front panel. The push buttons must be flush with the front side.
Test & building in Test and Usage Connect a 9 to 15VDC or a 8 to 12VAC to the points V and GND. (V is the plus pole in the case of direct current). Put the front panel film next to the keyboard and enter the right code (in the case of a pulse output this has to be done within 5 seconds). If everything is going on well, now the relay should close and open again in case pulse output mode has been ¬selected.
