VM-REMICA Remote Paging
Microphone Installation Sheet
Description
The VM-REMICA provides remote paging capability throughout a
building or campus. Each VM-REMICA has two inputs for connecting
other remote microphone units. The paging circuit supports up to
63 interconnected remote paging stations.
Installation
WARNING: Electrocution hazard. To avoid personal injury or death
from electrocution, remove all sources of power and allow stored
energy to discharge before installing or removing equipment.
Caution: Circuit boards are sensitive to electrostatic discharge (ESD).
To avoid damage, follow ESD handling procedures.
To install the VM-REMICA:
1.Remove the top retainer bracket on the back of the inner door on
the VM-RLCM remote annunciator cabinet. See Figure 1.
2.Loosen the nuts on the bottom retainer bracket.
3.Insert the VM-REMICA behind the bottom retainer bracket, and
then tighten the nuts on the bracket.
4.Reattach the top retainer bracket to the inner door to secure the
top of the VM-REMICA.
5.Set jumpers JP1 and JP2 as follows:
•Position A if AUDIO_OUT is connected to an EAEC
•Position B if AUDIO_OUT is connected to another
VM-REMICA
Wiring
Wire the VM-REMICA as shown in Figure 2.
Notes
•All wiring is supervised and power-limited.
•Test EOL resistors are installed on the remote microphone key
inputs to prevent trouble signals during installation. When
connecting field wiring to a next VM-REMICA, remove the resistors
from pins 12 and 13, and 16 and 17 on TB1.
•Remote microphones cannot be cascaded more than six deep on
a single circuit path.
•Install a 1.8 kΩ EOLR when key in is not used.
Testing
Note: Additional hardware may be required to adjust the microphone.
To adjust the microphone:
1.After the system amplifiers are properly balanced, press the push-
to-talk switch on the microphone. If you get feedback through the
system speakers, adjust the gain on the VM-REMICA until the
feedback is eliminated. See Figure 1 for the location of the gain
adjustment potentiometer.
