OPERATION WHEN CONNECTED TO THE GSM PRO INTERCOM VIA RS485
When the Art.4903 codelock is connected to the GSM PRO intercom via the RS485 terminals it can operate with additional access
control features (refer to the notes and Fig.16 on page 16, to the notes and Fig.41 on pages 27 - 29, and also programming features
in the programming section of this manual).
CORRECT CODE ENTERED ACCESS GRANTED
To operate:
1. Enter the access code for the respective relay followed by the
ENTER
button;
2. The green data LED (Fig.104,
) on the Art.4903 and the
red busy LED (Fig.104,
) on the GSM PRO will ash one
after the other;
3. The green data LED (Fig.104,
) will then ash once and
the appropriate relay (RLY1 or RLY2 depending on setup) will
activate and keypad will emit a series of 1 second interval
beeps for the duration of the programmed relay time.
If the speechboard is switched ON then the GSM PRO will
announce “the gate is open” or “the door is open”.
INCORRECT CODE ENTERED ACCESS DENIED
If an incorrect access code is entered:
1. The green data LED on the Art.4903 and the red busy LED on
the GSM PRO will ash one after the other;
2. Both the LED’s on the keypad will switch ON (Fig.105,
). The
green data LED will then switch OFF (Fig.105,
), followed
by the red status LED and the codelock will play a melody
(Fig.105,
);
3. No relay will activate.
If the speechboard is switched ON then the GSM PRO will

switched ON) when an access code is entered on the keypad.
