Bogen Communications Night Ringer NR100 90V video accessory

Night Ringer for 90V ring signals

The Bogen Night Ringer NR100 detects 90V ring signals or external contact closures and generates a dual-frequency electronic tone. It connects directly to any paging system and automatically mutes background music while the ringer is active. A built-in volume control lets you set the output level for the environment.

Interface limited to ring-voltage

The device only responds to a 90V ring voltage or a dry contact closure, so it cannot be driven by line-level audio, logic-level signals or network commands. No additional control protocols or digital interfaces are present, meaning integration is restricted to traditional telephone-style ringing circuits or simple switch contacts.

Suited for single-zone paging

The unit handles one paging zone and provides enough output for typical indoor spaces while drawing low current. It does not support multiple independent zones, programmable tone patterns or amplification for large-area coverage, so installations needing those capabilities will require additional equipment.
