Loud Bell / External Page / Music Source - Control - Comdial DX-80 Installation And Maintenance Manual

Loud Bell / External Page / Music Source – Control
There is often a requirement to control ancillary devices via the telephone system. The DX-80 system provides one
dry contact closure (standard) for interface of the various devices. It is important to adhere to the electrical
requirements of this contact. The contact closure is rated at 24vdc, 1Amp.
The Contact Closure can be assigned to operate in three different ways:
Loud Bell Control: If the system is installed in high noise environments, there is often a requirement to equip a loud
(high-gain) ringing device. Using the contact in this way provides for control of an optional, ancillary loud ringing
device. The device is connected to the contact as a trigger. When ringing occurs on CO Lines in CO Line Groups
designated as Loud Bell CO Line Groups, the contact closure operates and controls the connected device.
External Page Control: The contact may also be programmed to control External Paging apparatus. When
programmed in this manner, the contact closure operates whenever the External Paging Port is activated.
Music Source Control: The contact may also be programmed to control Message On Hold devices. In this mode of
operation the contact closes (make) whenever CO lines are placed on Hold. This function can reduce wear on
electromechanical devices that provide the message on hold function.
