ACCESS CONTROL WITH KEYBOARD
The DA-03 module will allow to control the access thanks to a keyboard any place or device. You could insert up to 10
different codes (composed by 4 numbers each code) which will be stored in memory even if you stop to supply the
module. It allows to authorize and deny codes and offers a relay output. The output could be flip-flop or timed types
with times adjustable between 1and 60 sec. Or 1 and 60 minutes.
It includes signal leds, acoustic signal, keyboard and connection terminals.

Do never desold, separate or make longer the communication cable installed betwen the PCB and the
keyboard.
The
you have to proceed
according to following instructions:
-
If you do not respect this point, the module could be damaged and the warranty cancelled.
- Install the module on an enclosure correctly ventilated. If you have to install the module outside, use a watertight
enclosure with a minimum interior space to allows to the module to dissipate heat without any problem during its
operating.
- Then, you have to protect the DA-03 module against bad weather, excessive humidity as well as against devices or
apparatus generating industrial parasites as coils, motors, neons, etc..
DA-03 circuit had to be supplied by a 12 VDC power supply correctly filtered. We recommended you the
FE-2 power supply which has been developed to perfectly answer to the circuit needs. Install a fuse and a switch has it i
sindicated ontheschedule. Both are necessary for the module’s protection as well as for your own safety, as it is required by teh
“CE” regulations. Connect the positive of the power supply to the positive terminal indicated in the wiring map, then connect
the negative of thepower supply to the negative terminal indicated in the circuit.

INFORMATION ABOUT THE DA-03.
OPERATIONS CONTROL.
Thanks to the operations control you could authorize and deny access code as well as program
relay timing. To activate the opetaions control mode, you have to connect, close or short-circuit both terminals of the JP1
jumper using the JP piece supplied with the module. See the corresponding schedule.
When the DA-03 is on this mode, the module could not be used as access control, and only accept operations control
management.
