External Emergency Mic

It is possible to use a microphone (Model MBS1000) with a contact closure to make an emergency announce- ment. The TELCO terminal on the back of the MCP35A control panel can be used to remotely trigger an emer- gency page on the system. Whenever the TELCO terminal is shorted to the GND terminal the MIC 2 input will become active and send audio to all rooms regardless of switch settings. The figure below shows the required wiring.

Note: Jumper J3 on the MCP35A printed circuit board must be set to the MIC2 posi- tion (this is the factory default setting). See the Special Adjustments section for jumper information.

Emergency Telco Page

Emergency pages can be triggered by devices other than a microphone. To use a source other than a mic, it is necessary to change the setting of a jumper inside the MCP35A control panel. See the Special Adjustments section for more information on the jumper change. Below are emergency telco page hook ups for various types of interfaces.

The Bogen model WMT1A can be used to convert the TELCO PAGE input to a transformer-balanced, 600-ohm input for telephone paging applications.

Note: Jumper J3 on the MCP35A printed circuit board must be set to the TELCO position. See the Special Adjustments sec- tion for jumper information.
