[1] Input current measurements are determined using test conditions
specified in UL 1711. Sine represents measurements made while the
unit produces a continuous, undistorted sine wave of 1 kHz into the
rated load of 25, 50, or 100 W at the rated output voltage. Alarm is the
average current the unit experiences delivering an alarm signal,
temporal whoop, to the rated load. Standby is the current draw of the
unit with all normal power on and auxiliary terminals fully loaded.
Battery standby is the current draw from the batteries on loss of power
in an otherwise normal standby state.
[2] All ANS cabinets hold two 12 V, 7 Ah batteries. Larger batteries
require an external battery cabinet.
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.
Note: if your system includes one or more ANSZS4B zone
splitters, the FACP EOLR must be relocated. See the
ANSZS4B installation sheet (P/N 3101185).
4. Connect the FACP signaling circuit to TB1-3(+) and
TB1-4(−), using the FACP alarm polarity.
5. Connect the mains power (120 Vac at 60 Hz) to the black
and white pigtail leads from transformer primary. Secure
the ground lead to the grounding stud in the cabinet.
6. Connect the battery wiring harness, Red(+) and Black(−).
Observe the correct polarity.
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.
