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 3 and 6 on the telephone.
BUILT-IN RELAYS – BACK EMF PROTECTION ART.4800M
The 4800M 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 “ENGINEER’S CODE”: first time type six times “1” (111111 factory preset) and press “ENTER” (The red LED will illuminate);
• Confirm “ENGINEER’S CODE” (typing again the same) or type the new code (4 to 8 digits) then press “ENTER” (Melody). Pressing
twice the “ENTER” button without changing the “ENGINEER’S CODE”, will exit from the programming;
• Enter the code (4 to 8 digits) to enable “RELAY 1” or re-enter the existing code then press “ENTER” (Melody);
• Enter the “RELAY 1” operation time (2 digits 01 to 99 I.E. 05=5 seconds, 00= remain open time) or re-enter the existing time then press “ENTER” (Melody);
• Enter the code (4 to 8 digits) to enable “RELAY 2” or re-enter the existing code 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 re-enter the existing time then
press “ENTER” (Melody);
• Enter the code (4 to 8 digits) to enable “RELAY 3” or re-enter the existing code 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 re-enter the existing time then
press “ENTER” (Melody);
• The system is ready to use (the red LED will be off).
PROGRAMMING NOTES
• After pressing enter following a command, press ENTER a further twice to exit the programming menu.
RETURN SYSTEM TO PRESET ENGINEER’S FACTORY CODE
• Turn off power to code lock;
• Keep “ENTER” button pressed while turning the power back on;
• Release “ENTER” button;
• The engineer’s code is now set to “111111” (six times one).
OPERATION
• Type in the programmed code and press “ENTER”;
• If the code is correct, the green LED will illuminate for approx. 2 seconds and the relay relevant to the code will operate for the programmed time;
• If a wrong code is entered, 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 seconds which will increase each time a wrong code is entered. The sys-
tem will operate only when the correct code is entered.
