The ANS series of products is a collection of high-performance audio notification systems that provide voice evacuation capability which meets the emergency voice alarm requirements of NFPA 72 for UL listed fire alarm applications. ANS panels are available in 25, 50, or 100 Watt models and include a microphone, amplifier, tone generator, digital message repeater (DMR), and supervisory interface.

These self-contained systems offer robust field-configurable features and are supported by a wide range of accessory equipment that provides application flexibility and reliable performance for new and retrofit installations alike.

Expander panels and modules extend the range of the ANS system to meet the needs of demanding audio applications. Accessory equipment such as zone switchers and remote microphones offer the sophistication of high-end systems for a relatively low cost.

ANS systems are ideal for use with Kidde fire alarm control panels when emergency voice alarm service is required. Genesis speakers and speaker-strobes may be used with ANS audio systems to provide a clean and attractive appearance for voice audio applications.

Application

National fire codes generally require voice evacuation systems in places of assembly with over 300-person occupancy, in theatres with more than one screen, and in buildings seven stories or higher. ANS Series Audio Notification Systems represent an effective and efficient solution for meeting these requirements.

ANS systems are ideal for new applications with fire control panels that do not provide integrated audio functions. These audio systems also provide the opportunity to add voice evacuation capability to existing fire alarm applications without replacing existing fire alarm control equipment.

The fire alarm control panel works in concert with the ANS audio system, providing all initiating circuitry and a signaling circuit that connects to the ANS. The ANS provides its own internal supervision as well as supervision for its speaker lines.

Faults are reported back to the fire alarm control panel by means of a supervisory circuit, which is connected to a matching EOLR on the ANS. Internal failures and speaker line faults open a contact, which the fire alarm control panel reports as an open fault on the supervisory circuit.

A digital message repeater (DMR) is built into all ANS systems unless ordered without the DMR. Up to 20 minutes of custom messages can be uploaded in the field with the use of a laptop and the ANSCONFSOFT1 configuration software. In addition, the selection from eight available alarm tones, automatic message repeats, AC fault report delay, and connected equipment settings are all field-configurable.
