5.8. Wiring the circuit:
• Cut three 100mm long lengths from the insulated wire and tin the ends. Insert one wire through the hole
in the switch panel and solder the end to the first row of drawing pins. The rest of the wiring is carried out
as shown in the diagram.
• The code for the door opening is 4 -6- 3. Of course another code can be 'wired' up.
• Screw the shelf (21) on the pine strips (2) (Use two roundhead screws)
5.9. Testing:
The safe can be opened only when the correct code is entered. The door is opened by the action of the
gearbox and mechanism, which in turn is operated by the relay and motor. The code is made up from the
action of three switches. We have chosen the code 4-6-3. To open the door you must press the fourth
switch in the top row and the sixth switch in the middle row at the same time. The relay is now activated
and you only have to press the third switch in the bottom row and the door should open. The motor will
only work as long as the switch 3 is pressed. If an incorrect switch in the bottom row is pressed a short
circuit is made and the relay is de-activated. The switches in rows 1 and 2 must
then be re-pressed.
Note:
Do not press a switch in the bottom row when the door is closed, otherwise the contact
in the relay will activate and the battery will run down.
