Valcom, Inc Loud Warble Horn handheld pcs accessory 90 Vac 18 Vac 5 Watt 4.7lbs Beige

Valcom Loud Warble Horn accessory

The Valcom loud warble horn is an external audible signal device designed for PBX or station line integration. It suits installers and technicians who need a standalone alerting unit for business telephone systems. The beige enclosure houses a built-in tone generator and a 5 Watt amplifier with volume control.

Activation voltage limits

The unit activates on a 90 Vac ring signal or an 18 Vac buzzer voltage, so it connects directly to compatible lines without an external power supply. It does not operate on DC voltages or other AC levels, and the fixed input thresholds cannot be adjusted. Installers must verify that the host system provides one of these two exact voltages.

Replaces basic ringers and buzzers

This horn replaces simple mechanical ringers or low-output electronic buzzers when a louder, more distinct warble tone is required in noisy environments. The jump is worthwhile when the existing alert cannot be heard over background noise or when a single device must cover a larger area. It is not suited for installations that require multi-tone programmability, network-addressable signalling, or visual strobe alerts.
