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.

Installation instructions

Ensure that all wiring and devices installed in the system meet

the following standards:

• NFPA 70 National Electrical Code

• NFPA 72 National Fire Alarm and Signaling Code

• NFPA 101 Life Safety Code

• Applicable state and local codes

Install this equipment in a clean, dry environment. Avoid installation where the equipment could be subjected to vibration. Remove all electronic assemblies from the enclosure before drilling or punching the enclosure. Where possible,

make all cable entries from the rear or sides. Before making

any modifications to the enclosure, be certain that they will not interfere with the assemblies or batteries.

Wiring instructions

Refer to Figure 1 for terminal designations, and to diagrams in the “Applications” section for wiring diagrams.

1. Connect the speaker lines to TB1-5(+) and TB1-6(−).

Be sure to observe polarity and connect all speakers using

the same polarity. For Class A (Style Z) the returns are TB1-7(−) and TB1-8(+).

Note: When using 70 VRMS speakers, the speaker wiring

must be enclosed in grounded metal conduit.

2. Connect the microphone to connector P2.

If the microphone is not installed, ensure that switch SN2-8 is in the OFF position.

3. Attach the appropriate EOLR for the FACP to TB3-3 and 4

and for the speaker circuit to TB3-5 and 6.

You must use EOLR value specified for the FACP

notification appliance circuit (NAC). See the FACP installation instructions provided by the manufacturer.

2 / 12 P/N 3101179 • REV 03 • REB 28FEB13

Use two 12 V batteries connected in series. (See

Figure 4.) If the unit does not have its own batteries and

relies on an external power supply with battery backup,

ensure that switch SN2-7 is in the OFF position.

Note: Wiring for batteries is nonpower-limited. Maintain a

minimum spacing of 1/4 in. between power-limited wiring and nonpower-limited wiring.

If the batteries must be located in a separate enclosure, provide a separate conduit run for the battery wiring only.

7. When all power and circuits are connected, the green LED turns on (and stays on) to indicate that the ANS is fully operational and all circuits are normal.

Terminal designations

Refer to Figure 1 for the locations of the terminals.

MSG GAIN and MIC GAIN

The MSG GAIN (message gain) and MIC GAIN (microphone gain) potentiometers are factory set and should only be adjusted by trained technicians with the proper test equipment.

To increase the output of a speaker, change the speaker tap connection or setting to a higher wattage.

Switch S1

Pressing switch S1 performs a hard reset of the ANS microprocessor. This is not required during normal operation, and should only be done at the request of our support technicians.

Options

Aux +24 Vdc output

Terminals TB2-4, -8, -9, and -10 provide a maximum of 200 mA of regulated 24 Vdc power for auxiliary functions. Do not exceed a combined load of 200 mA on these terminals. These

terminals are for connection to ANS accessory modules and listed general signal devices only and are not for use with fire

protective signaling applications. Terminal TB2-4 activation is programmed in the U6 EPROM chip. Standard chips are programmed for TB2-4 to go active (+24 Vdc) under the

following conditions:

• Aux signal active

• Aux audio enable

• Bell circuit active

• RSI active

Reprogramming of these functions must be done at the factory and requires replacing the EPROM U6.

Aux audio source connection

Terminals TB2-1 and -2 allow connection of an aux audio source from additional paging equipment to augment an

existing paging system. This option is not intended for

continuous signal input, but may be used for paging

applications. For such an operation the aux audio enable input, TB2-6, must be powered from the interrupted V+, TB2-9. This ensures that in the event of an alarm, the aux audio will not

override the evacuation signal. See Figure 9 for connection

details. Use of an ANSAUX Audio Transponder Module may

be required for some audio sources (to match the auxiliary audio line signal.)

Optional supervisory circuit

Terminals TB3-1 and -2 can be used to connect a supervisory circuit from the FACP to the ANS. In place of normal supervision via the notification appliance circuit, an alternate method may be employed using any supervisory circuit from

the FACP. TB3-1 and -2 provide a normally closed connection to the EOLR on TB3-3 and -4. The relay contact in the circuit

opens on any trouble condition and reports an open circuit trouble to the FACP.
