Regulations:

FCC (Part 15) Radio Frequency Interference

The BOMDMU generates and uses radio frequency energy and if not installed and used in strict accordance with the manufacturer's instructions, may cause interference to radio and television reception. Unit complies with the limits for Class A devices in accordance with the specifications in Subpart J of Part 15 of the FCC Rules. This testing is designed to provide reasonable protection against such interference. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause interference to radio or television reception, which can be determined by turning the unit off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

 Reorient the radio or TV receiving antenna.

 Relocate the unit with respect to the radio or TV receiver or vice-versa.

 Plug the unit into a different outlet so that it and the radio or TV receiver are

on different branch circuits

 If necessary, the user should consult the dealer or an experienced

radio/television technician for additional suggestions.

1. OVERVIEW

1.1 Features and Capabilities

The BOMDMU is a comprehensive system that combines Page Stacking, Feedback Elimination, Pre-Recorded Messaging and Background Music control into a single device.

PAGE STACKING/FEEDBACK ELIMINATION: For busy overhead paging systems, the BOMDMU offers 3 channels of page stacking and feedback elimination. Each channel can record and temporarily store up to 16 pages or 4 minutes of audio. Page input channels can record simultaneously, and while the system is playing.

PRIORITY PAGING: For emergencies, the BOMDMU offers a priority input that overrides the stacking and messaging functions and provides immediate, real-time access to the paging system.

PRE-RECORDED MESSAGES: For security and general public address messaging, a pre-recorded messaging sub-system has been included. Access both Record and Play functions of up to 99 messages/8 minutes of audio from an extension on your host telephone system. Ten (10) start contacts have also been provided to trigger messages from external devices such as sensors or alarm systems.

BACKGROUND MUSIC: To keep everything in harmony, the BOMDMU also includes a background music input. This allows playback of your favorite music source over the paging system. When a page or message is played, the background music will be muted and the announcement will be heard loud and clear.

2. INSTALLATION & CONFIGURATION

This section provides complete instructions for mounting the BOMDMU in a rack or on a table. It also illustrates all interface requirements to auxiliary equipment, including inputs and outputs. Configuration switch settings are provided.

2.1 Installation Steps

These are the general steps for installation:

1. Find a space in a rack or on a table. Mount the unit to the selected place with its wiring at least 18” away from the power supply or other equipment that generates electrical noise. Secure unit using the supplied mounting screws.

2. Make sure there is a standard electrical outlet into which you can plug the power pack. This outlet should NOT be controlled by a wall switch.

3. Make cable connections from the BOMDMU to the PBX or audio source and the Paging system,

4. Set DIP switches to the desired operation.

5. Connect the power supply. System OK LED should illuminate GREEN.

6. Test unit operation.

2.2 Hardware Description

FRONT

The BOMDMU is a standard 1RU 19” rack mount chassis.

The front panel of the BOMDMU provides user indications of the system status via LEDs. The description of each LED can be found in section 2.2.1 of this manual.

Configuration switches are also accessible on the front panel of the unit. The description of the various user configurable settings can be found in section 2.2.14 of this manual.

4 17

BACK

The back panel of the BOMDMU provides all electrical connections to the device. The connector type and signal descriptions are detailed later in this manual.

Individual configuration of each audio input / output port is provided next to each audio input connector.

Volume controls are provided for the BGM input and the audio output.

Flanges are provided on each side of the back panel of the BOMDMU to provide strain relief to all the wiring routed to the BOMDMU.

2.2.1 Status LED Indicators

All Status Indicators are located on the front panel of the unit. The

different groups of LED indicators are described below:

2.2.1.1 System

The System indicators are global indicators that indicate that a particular function is active on any, or all, of the inputs on the system.

System OK LED – Green, indicates unit is ON. Flashing indicates an

error condition, contact the factory for more information should this occur.

Recording LED - Red, indicates that a recording session is active on

any one of the paging inputs.

Playing LED - Green, indicates that the audio output of the BOMDMU

is active due to a page playing back, or the priority input being active.

Busy LED - Yellow, indicates that any one of the paging inputs is

recording, playing, or in a delay mode. This LED is also active when a priority announcement is being made.

2.2.1.2 Message Input Messaging Input Off Hook LED - Yellow, indicates the messaging

system is being accessed via a phone circuit. (Loop current flowing)

Messaging Input Level LED - Yellow, indicates audio signal is present

on the Message Input.
