Function Description 3.3343.3 Function DescriptionFrom External User's View (Visitor)Like normal doorbells, intercom buttons are provided with labels. The visitor finds theappropriate button (e.g. Mr. Smith) and presses it. This activates the intercom, whichthen dials the number pre-programmed for that button, The visitor can then hear theringing tone from the loudspeaker and the required (Mr. Smith’s in this case)telephone is ringing. If the intercom is connected to a telephone system, you can tagthe port the intercom is connected to in order to see on the ringing phone that it is theintercom that is calling. When the called party answers the call, the visitor and thecalled person can speak to each other and, if an electric lock is connected to theintercom, the called person can open the door by entering the correct password on thetelephone keypad to activate the door or barrier. When the caller hangs up, theintercom detects the PBX or analogue line tone and hangs up too. The intercom alsohangs up when it “hears” the busy tone or if the call takes more time than as pre-programmed to connect. You can pre-program the amount of time that you have tospeak into the microphone, but when you reach the programmed time, the unit willsend a warning tone 10 seconds before hanging up so that the called party can extendthe call if required.Note If the visitor presses another button during the call, the intercom hangs upfor a few seconds before dialling the new number. If a button is pressed that has no number stored within it, the intercompicks up the line, sends a refusal tone (refer to the Signals Overview) andhangs up. If the visitor presses the same button during the call, the intercom mayhang up (can be programmed to stop this feature if required). The above mentioned rules are only applied if the Automatic MultipleNumber Dialling mode is OFF. For this special mode refer to the AutomaticMultiple Number Dialling section.Function Description – Numerical Keypad Models2N® Helios Force model 9151201K-E is equipped with a numerical keypad.
