PVC-RMI
Intelligent Remote Mic
The PVC-RMI Remote Mic Interface is mounted in a remote cabinet. The PVC-RMI expands the ability to
Page and control conventional PVX system functions from multiple remote locations. The PVC-RMI operates
as the host for remote PVC-SL8 switch banks as well as the PVC-IL8 input and PVC-OL8 output interface
cards. It communicates these functions to the system
The PVC-RMI has an address DIP switch which determines the device address on the RS-485 loop. This
address switch is set between 1 and 31. A maximum of 31 RMI units may be . SW1 is turned
“on” at the last device to mark that device as the “end of line”.
LED 1 is the Status LED. It flashes Green during normal standby condition to show that the device is
operational. LED 1 will be Green steady when the Microphone PTT button is engaged and the unit is
asserting the audio line. LED 1 will flash Amber to indicate a Fault condition on this device.
LED 2 is the In Use indicator. It will be Red steady when another device is The
primary PVX 25/50/100 will always have highest priority. It will override any other PVC-RMI as long as its MIC
PTT is activated. If there are multiple RMIs in the system, the first to activate its MIC PTT will assert the
audio line. When its MIC PTT is released another may activate.
SL8 LEDs: On the Switch/LED card utilized with the PVC-RMI, LEDs will indicate Steady Red for Paging,
Flashing Red for Alarm.
Installation:
Installer must insure that all wiring and devices installed in system meet the following standards:
National Electrical Code (NFPA 70) / NFPA Standard 72
Models: PVC-RM8 (8 switches) / PVC-RM16
Mounting: is intended to mount within the PVC-RM8/16 cabinet on stand-offs.
For PVC-RM24 - PVC-RM128 mounting of components will be within a CAB102 with a windowed door.

PVC-RMI may be powered separately
by a 24VDC Power Supply Listed to UL2572 or UL1481.
Power Supply must be mounted adjacent to PVX 25/50/100
and have Circuit Negative tied common to the PVX 25/50/100.
24VDC Power connects to PVC-RMI, not to the PVC-100M.
All other connections remain the same.
Power Supply must be tied to the same AC Branch circuit as
the PVC-100M.
