The Federal Signal UltraVoice™ is designed to provide one- or two-way control of high-power electronic sirens such as the MOD or DSA, or to control indoor AudioMaster speaker systems. UltraVoice produces amplified audio signals including seven built-in warning tones, high-quality live public address, and pre-recorded voice messages.
The UltraVoice is housed in two cabinets. The control cabinet houses the control module and amplifiers. A separate vented cabinet houses the batteries. The standard cabinet for the UltraVoice is made from 5052-H32 grade aluminum. This control cabinet is also available in 304 or 316 stainless steel. The number of amplifiers and batteries (purchased separately) required by an UltraVoice Controller depends on the power required by the specific siren array or speaker system.
Two-way systems provide siren status to the control station and include a sensor package, radio transceiver and encoder/decoder. Computer controlled status monitoring of the following conditions is provided: AC Power, Battery Voltage, Charger Operation, Activation Current, Signal Line A and B, Mode of Operation, Quiet Test, Intrusion, and Local Activation.
UltraVoice units may be equipped with a programmable RF receiver for remote control using MSK, DTMF or Two-Tone Sequential protocols. Pre-recorded digital voice messages can be added by simply plugging in a four- or eight-minute IC chip. Windows®-based software is available that allows users to configure activation sequences.
