ANSREM Remote Microphone Installation Sheet

Product description

The ANSREM is a supervised remote microphone panel for
use with the ANS25, ANS50, and ANS100 audio notification
systems. The ANSREM makes it possible to send emergency
voice messages through the system speakers from a location
that is remote from the ANS panel.

The ANSREM uses 3-pair shielded cable to connect to
ANSREMSUP supervisory card, which is mounted within the
ANS master panel. Fault conditions in the wiring or in the
remote microphone circuitry are reported to the fire alarm
control panel (FACP) using the same supervisory path as the
ANS master panel.

Operation

When the system is in the alarm state, keying the ANSREM
microphone interrupts the alarm signal and digital message.
Live voice messages can then be broadcast over the system.

When the system is in normal standby state, the ANSREM
microphone can be keyed to make announcements at any
time.

Keying an ANSREM microphone at any time turns on the
In Use LEDs on all other ANSREMs, and disables the other
units. This ensures that only one operator is able page over the
system. If the microphone in the master ANS panel is keyed, it
overrides all ANSREM microphones.

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
locations where equipment is 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.

Make sure all power is off before making any wire connections.

Refer to the wiring, terminal designation, and application
diagrams that follow.

1. Run 3-pair shielded wire (22 AWG minimum) from the ANS
master panel to the ANSREM remote microphone location.

2. Mount the ANSREMSUP supervision card in the ANS
master cabinet, using snap-track.

Attach snap-track to the ANS master cabinet as required. The
supervision card may already be factory-mounted and wired.

3. Make the wiring connections shown in Figure 1.

4. Verify correct installation of the end-of-line resistor (EOLR)

on the ANSREM.

Each module is shipped with an EOLR installed. When the
system has multiple ANSREM units, verify that the EOLR
is installed on the last unit only.

5. Apply power to test the system:

a. Test the ANS master microphone.
b. Test ANSREM remote microphone.

6. Place the panel in alarm and retest the ANS master
microphones:

a. Ensure that the tone and message are broadcast.
b. Test that keying the microphones overrides any

automatic message or tone.

Figure 1: Wiring the ANSREMSUP

(1) All wiring from ANSREMSUP is power-limited. All wiring must be

routed to maintain minimum spacing from any nonpower-limited
wiring.

(2) When circuits are power-limited, use power-limited cable as

detailed in the National Electrical Code, Article 760, such as FPL
or FPLP type cabling.

(3) Battery cabling is nonpower-limited. Do not route any power-

limited wiring within 1/4 in. of the battery cabling.

Figure 2: Wiring the ANSREM

The ANSREMSUP must be mounted in the ANS enclosure or in

another UL Listed cabinet within 20 ft. and connected using conduit.

The ANSREMSUP must be mounted using metal standoffs or an

earth ground connection must be made to TB2-7.
