Test & 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. If however you have chosen for a constant switch position, then
you can cause the relay to open by entering a digit NOT belonging to the code digits.
Tip: should the opening time of the relay (in the case of the pulse output mode) be too short, fit a 22µ F
capacitor instead of C1 to change that time.
Test & usage
In case you use the key lock outside, it is advisable to mount it sunk, so that no water can soak in. For safety
you better first fix the code lock into the wall where after you stick the film to it, so that the fixation screws are
hidden "behind" the film.
Take care that, when sticking the film, the "LED WINDOW" corresponds with the hole in the aluminium.
