ACTIVATING THE ART. 4850R EXPANSION READER’S ONBOARD RELAY
The Art.4850R expansion reader must be connected via
RS485 to the GSM PRO intercom (refer to wiring diagrams
on page nn), setup with a unit ID, the correct number of
bytes setup and fobs/cards stored using the EPR, PBY and
FOB commands (refer to the relevant setup notes and
programming notes on previous pages).
In standby the status indication LED on the front of the
Art.4850R reader will be switched ON (amber).
ACCESS GRANTED
To operate the relay on the reader present a programmed
fob/card to the proximity reading area.
Once the fob/card is presented the status LED will change
from amber to green and the onboard relay will activate for
the duration of the programmed relay time. The reader will
also emit a double beep, while the busy LED on the GSM
PRO intercom ashes ON and OFF, see Fig.100.
ACCESS DENIED
If a fob/card is presented to the reader that is not stored in
the GSM PRO intercom the status LED on the front of the
reader will change from amber to red and will emit 1 short
beep followed by a short double beep, while the busy LED
on the GSM PRO intercom ashes ON and OFF, see Fig.101.

ACTIVATING THE ART. 4903 CODELOCK’S RELAYS
STANDALONE OPERATION I.E. NOT CONNECTED VIA RS485
The Art.4903 codelock can operate as a standalone keypad with up to 2 access codes only (1 code per relay), where the codes are
programmed directly via the keypad (refer to programming and setup notes on pages 14 - 16, also refer to the wiring diagram
Fig.25 on page 21).
CORRECT CODE ENTERED ACCESS GRANTED
To operate:
1. Enter the correct access code for the respective relay, via the keypad,
followed by the ENTER
button. The appropriate relay (i.e. RLY1 or RLY2
depending on setup) will activate for the programmed relay time;
2. The green data LED will ash once and the codelock will emit a series of 1
second interval beeps for the duration of the programmed relay time, see
Fig.102.
INCORRECT CODE ENTERED ACCESS DENIED
If an incorrect access code is entered:
1. No relay will activate.
2. The codelock will emit a low tone and the green data LED (Fig.103,
) will
ash 4 times followed by a brief pause;
3. The red status LED (Fig.103,
) will then ash once and the codelock will
emit a single beep.
IMPORTANT NOTE: The keypad’s relays RLY1 and RLY2 can also be activated
via a push to exit button (when congured as a push-to-make switch) when
connected across - and SW1 for RLY1, - and SW2 for RLY2 respectively. It
should also be noted that when the relay time has been set for latching (00)
the push to exit button will operate as a “toggle” switch to latch the relay
open and latch the relay closed.
