system automatically hangs up if the call is not answered, 2) a single or double ring (when set for
double ring, the first ring will be a single ring). A two digit number will be entered to set up these
operating parameters, with each number of the code corresponding to the respective functions listed.

3.1.8 Tone Open Number Programming
The tone open number is the number that is pressed on the resident’s telephone to activate the relay
on the 1885 control board. The resident can only activate the relay momentarily, but other relay
functions are available from the doorman/concierge phone and by remote relay activation. The four
relay functions are: 1) momentary activation, 2) continuous activation (relay latch), 3) deactivation
(unlatch), 4) activate for one hour, then automatically deactivate. If a function is not going to be used,
enter a # sign in place of the respective digit. Do not use the number "3" as a tone open number
since this number is reserved to activate the call waiting feature. Do not duplicate tone open
numbers.
NOTE: When used with a DoorKing Lobby Panel, the 1820 and lobby panel Tone Open
Number programming must match. Refer to the lobby panel programming instructions to
program the lobby panel Tone Open Number programming.
