3. Setup
3.1 Unpacking
Carefully remove the Night Ringer from its packaging. Inspect the unit for any signs of damage that may have occurred during shipping. If damage is found, contact your supplier immediately.
3.2 Mounting
The BG-NR100 is designed for surface mounting. Use appropriate screws (not supplied) to secure the unit to a wall or other stable surface using the mounting tabs on either side of the enclosure. Ensure the mounting location allows for adequate ventilation and access to connections.
3.3 Wiring Connections
All connections are made via the screw terminal block located on the front of the unit. Ensure power is disconnected before making any wiring connections.
| Terminal Label | Description | Function |
|---|---|---|
| TEL RING (T, R) | Telephone Ring Input | Connect to the tip (T) and ring (R) lines of a standard 90V telephone ring signal source. |
| CONTACT RING (A, B) | External Contact Closure Input | Connect to a dry contact closure (e.g., from a relay or switch) to trigger the ringer. |
| POWER SUPPLY (+24, -24) | Power Input | Connect to a regulated 24V DC power supply. Observe polarity (+24V to +24, -24V to -24). |
| BGM SOURCE (A, B) | Background Music Input | Connect the background music source here. The unit will mute this input during a ring event. |
| AMP INPUT (A, B) | Amplifier Input / Output to Paging System | Connect this output to the input of your paging amplifier or public address system. This carries the ringer tone and the muted BGM. |
4. Operating
4.1 Basic Operation
Once properly connected and powered, the BG-NR100 will automatically detect an incoming 90V telephone ring signal or a closure on the Contact Ring terminals. Upon detection, the unit will generate a dual-frequency electronic ringer tone and simultaneously mute any background music connected to the BGM Source input. The ringer tone will be sent to the Amp Input terminals for connection to your paging system.
4.2 Volume Control
The ringer volume can be adjusted using the TONE VOL knob located on the top left of the unit. Rotate the knob clockwise to increase the volume and counter-clockwise to decrease it. Adjust the volume to a suitable level for your environment.
5. Maintenance
5.1 Cleaning
To clean the unit, wipe the exterior with a soft, dry cloth. Do not use liquid cleaners or aerosol cleaners. Ensure the unit is powered off and disconnected from all sources before cleaning.
5.2 General Care
The BG-NR100 is designed for reliable operation and requires minimal maintenance. Ensure it is installed in a location free from excessive dust, moisture, and extreme temperatures. Periodically check all wiring connections to ensure they are secure.
6. Troubleshooting
If you experience issues with your Bogen BG-NR100 Night Ringer, refer to the following table for common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| No ringer tone output. | No power to the unit. | Check power supply connections and ensure 24V DC is present. |
| Incorrect or no input signal (TEL RING or CONTACT RING). | Verify 90V ring signal on TEL RING or proper contact closure on CONTACT RING. | |
| Volume knob set too low. | Adjust the TONE VOL knob clockwise. | |
| Ringer tone is distorted or weak. | Improper connection to paging amplifier. | Ensure AMP INPUT is correctly connected to the amplifier input. Check amplifier settings. |
| Background music does not mute. | BGM SOURCE not connected correctly. | Verify BGM SOURCE connections. Ensure the music source is routed through the Night Ringer. |
If the problem persists after attempting these solutions, please contact Bogen technical support or a qualified service technician.
