Edwards ANS Amplifiers Install

Audio Notification System Installation Sheet description Audio Notification System ANS is a self contained tone generator digital message repeater and interface It is designed for use with a UL Listed alarm control panel FACP to provide a listed voice alarm system See Table 1 for a list of ANS FACP provides all initiating circuitry and a notification circuit NAC that connects to the ANS The ANS its own internal supervision and supervision for its lines The ANS reports faults to the FACP by placing open on the FACP NAC Optionally faults can be reported the FACP by connecting a supervisory circuit to the ANS ANS reports internal failures and speaker line faults by an open on the supervisory circuit models of the ANS are powered by a 120 V 60 Hz supply the ANS can be powered by 24 Vdc from a UL Listed alarm power supply Each model provides a different power but all models can be configured for 25 or 70 Vrms by jumper The factory setting is for 25 Vrms models model numbers have the format ANS999MDC Each is a complete audio notification panel including a built in generator power transformer and cabinet The 999 represents the output power 25 50 100 150 or watts M indicates the inclusion of a microphone D the inclusion of a digital message repeater DMR C the cabinet color either gray G or red R model numbers have the format ANS999XC Each is a complete expander panel including a built in tone power transformer and cabinet The 999 portion the output power X indicates an expander module have no microphone and no DMR C indicates the color either gray G or red R model numbers have the format AMS999AMD The include a built in tone generator but no transformer cabinet The 999 portion represents the power output The A indicates an amplifier M indicates the inclusion of microphone D indicates the inclusion of a digital message Expander can operate as a slave amplifier when connected an ANS999AMD which supplies source audio to the slave can also operate as stand alone audio notification with only tone and microphone amplification models use multiple amplifier configurations These are configured and prewired at the factory 1 ANS models number W ANS W ANS W ANS W ANS W ANS
