12VDC 2A POWER SUPPLY HDR1512
The 4G GSM intercom is designed to work with power supplies
in the range of 12Vdc and should be capable of supplying a
constant current of no less than 1A.
The Art.HDR15-12, Fig.6, is a DIN rail mount slim line
power supply that is supplied with both the GSM4K/4G and
GSM4KCR/4G series audiokits.
It has a mains voltage input of 230-240Vac, 50/60Hz and an
adjustable 12Vdc output.

ART. 4903 CODELOCK
The Art.4903 codelock module (included as part of the GSM4KCR-n/4G and GSM4KCR-nS/4G kits) can be powered from 12-24V
AC or DC and includes 2 dry contact relay outputs and two switched 0V push to exit inputs which can be used to trigger relay 1 & 2.
It also includes an RS485 bus connection which can be linked to the 4G GSM module and networked with other Art.4903 codelocks
and/or Art.4850R proximity devices (up to 8 devices in total).
When connected to the 4G GSM via the RS485 connection it can operate up to 400 permanent access codes (000-399) which can be
assigned to trigger relay 1 or 2 or both. The permanent codes can also have access levels and timebands assigned to them.
It can also operate up to 32 temporary codes which are valid from 1 to 255 hours. The codes can be between 4 - 8 digits long and are
stored on the 4G GSM intercom and in the case of the temporary codes they will automatically be deleted after the validation time
has elapsed. Also the temporary access code validation time period will begin its count down from the rst use of the code.
