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