DoorKing 1803 Entry System - Manual (Page 26)

2.4.6 Master Code Switch
The master code switch is left in the off position for normal operation. Turn the master code
switch on when setting the system master code. See programming instructions to set the
system master code.
If the master code switch is turned on and a new master code is not entered, the system will
sound a long tone after approximately 30 seconds. This tone will continue every 30 seconds
until a new master code is entered, or until the switch is turned off. After the switch is turned
off, the display (1803, 1810 only) will remain lit for approximately 30 seconds, and then will go
off.
2.4.7 Ring Pin
The ring pin-shorting bar is labeled RING on the control board. This shorting pin must be
installed to allow the system to answer any calls placed to it. If remote programming or
remote relay operation is to be used, the shorting bar must be installed. Removing the
shorting bar will cause the system to never answer any call placed to it.
2.4.8 Handset / Hands Free
The handset shorting pins are labeled HS, and the hands free shorting pins are labeled HF
on the control board. The shorting bar is factory set and will be placed in the HF position for
hands free operation, or will be placed in the HS position for those entry systems ordered
with the optional handset. Do not place shorting bars on both the HS and HF pins at the
same time.
