Common Bell
If you connect a common bell to the general-purpose dry contact pins of the MISC port, the
common bell can receive a call signal as if it is one of the stations. You can select a continu-
ous bell or an interrupted bell using MMC 204, Common Bell Control. When an interrupted
bell is selected, a trunk call signal (1 second ON / 2 seconds OFF) should be designated.
After connecting a common bell, you can designate a station group through MMC 601, As-
sign Station Group, using a common bell code.
NOTE: You can use a common bell for receiving a call from a particular direct trunk. A relay
controlling the common bell is used with low voltage and low current so that the common bell can
only be used under 5Vdc and 40mA.
