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.
