BUZZEr BACK EMF
When using intercoms with buzzer call (Art. 924/926, SMART1/2, 3101/2, 3001/2 and 3021/2) add one 0,1uF capacitor between
terminals 6 and 3.
BUILT-IN rELAYS – BACK EMF PrOTECTION ArT. 4900M
The Art. 4900M includes selectable back EMF protection on the relays. The jumpers marked MOV (One jumper for each relay) are
used to select the protection type. When using a fail secure lock with connections C & NO the jumper should be in the NO position.
When using a fail open lock with connections C & NC the jumper should be in the NC position and when using the codelock to
trigger a gate controller or another third party controller the jumper should be removed completely (This disables the protection
on the relay).
PrOGrAMMING (SEE ALSO THE rELEVANT FLOW CHArT)
• Enter the “MASTER CODE”: first time type 8 times “1” (11111111 factory preset) and press “ENTEr” (The red LED will illuminate);
• Confirm “MASTER CODE” (typing again the same) or type the new one (4 to 8 digits) then press “ENTEr” (Melody). Pressing twice
the “ENTEr” button without changing the “MASTER CODE”, will exit from the programming;
• Enter the “USER NUMBER” (2 digits from 00 to 99) then press “ENTEr” (Melody);
• Now you can do two different operations:
1. If you press “CLEAr” the code relevant to the “USER NUMBER” entered is deleted and the system go back to “USER NUMBER”
entering (melody);
2. Enter the “USER CODE” (4 to 8 digits) then press “ENTEr” (Melody). The user code must be prefixed with 1 digit that specify
the relay to operate: 0 relay 1 and 2, 1 relay 1, 2 relay 2 and 3 relay 3. I.E. the code 148325 would operate the relay 1 only.
• The system go back to “USER NUMBER” entering. Continue as above to delete or enter other codes or press twice “ENTEr” to
jump to next programming step (Melody);
• Enter the “RELAY 1” operation time (2 digits 01 to 99 I.E. 05=5 seconds, 00= remain open time) or leave the existing time then
press “ENTEr” (Melody);
• Enter the “RELAY 2” operation time (2 digits 01 to 99 I.E. 05=5 seconds, 00= remain open time) or leave the existing time then
press “ENTEr” (Melody);
• Enter the “RELAY 3” operation time (2 digits 01 to 99 I.E. 05=5 seconds, 00= remain open time) or leave the existing time then
press “ENTEr” (Melody);
• The system is ready to use (the red LED will be off).
PrOGrAMMING NOTES
• After the confirmation of an entered data by pressing the “ENTEr” button, by pressing twice the same button you can exit from
the programming.
rETUrN SYSTEM TO PrESET MASTEr FACTOrY CODE
• Turn off power to code lock;
• Keep “ENTEr” button pressed while turning back on the power;
• Release “ENTEr” button;
• The master code is now set at “11111111” (eight times one).
OPErATION
• Type in the programmed code and press “ENTEr”;
• If the code is right, the green LED will illuminate and the re-
lay will operate for the programmed time;
• If a wrong code is “ENTEr”ed, a continuous melody will
sound for 4 or more seconds, according to the number of
mistakes;
• To switch off any relay while operating, type in the relevant
code then press the “CLEAr” button.
OPErATION NOTES
• To operate relays together, set the same code for each relay;
• If a wrong code is entered, the system will lock out for 5 sec-
onds which will increase each time a wrong code is entered.
The system will operate only when the correct code is entered.
