kits and installation instructions.
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.
Note: Two-way firefighter telephone communication requires a
VM-MFK Master Firefighter Telephone Kit.
To install the VM-PMI:
1. Attach the audio mounting bracket to the cabinet backbox using
the K-nuts provided. See Figure 2.
2. Install the EAEC card on the audio mounting bracket using the
screws provided.
3. Mount the audio enclosure on the audio mounting bracket hinges.
See Figure 4.
4. Connect the ribbon cable (P/N 250194-01), with the red edge
down, to J1 on the audio user interface card.
5. Insert the cable under one clip on the cable clamp that is affixed to
the enclosure, and then connect the other cable end to J1 on the
EAEC card. See Figure 4.
6. Loosely secure the cable to the mounting bracket using the nylon
cable tie provided.
7. Connect the ribbon cable (P/N 250188-01) to J3 on the EAEC card
and J5 on the PS10-4B power supply card that is mounted on the
backbox behind the electronics chassis.
8. Swing the audio enclosure toward the backbox to close it, sliding
the screw holes on the right flange onto the two screws on the
backbox. Secure the enclosure using the two #8-32 K-nuts
provided.
9. Peel off the black film on the inside of the bottom viewing window
of the cabinet door.
Wiring
Connect the VM-PMI field wiring as shown in Figure 5. See Table 1 for
descriptions of the connectors on the audio user interface card.
Notes
• All wiring is supervised and power-limited.
• Maintain 0.25 in. (6 mm) separation between power-limited and
nonpower-limited wiring at all times. Keep nonpower-limited wiring
in the shaded area shown in Figure 1. Secure the wiring to the
cabinet using nylon cable ties.
• If a VM-NOC card is not installed on the VM-CPU, connect AUDIO
DATA on the EAEC card to AUDIO A OUT on the VM-CPU
network data and audio terminal. See Figure 5.
If a VM-NOC card is installed, connect AUDIO DATA on the EAEC
card to AUDIO A IN on the VM-CPU network data and audio
terminal.
• Wiring from a remote microphone must be shielded and enclosed
in conduit. Refer to the VM-REMICA Remote Paging Microphone
Installation Sheet (P/N 3101795-EN) for field wiring instructions.

Overview

1. Function Description
2. Important Technical Specifications
3. Usage Features
4. Maintenance Features

The VM-PMI Paging Microphone Interface is a critical component for emergency voice/alarm communication and two-way firefighter telephone communication systems. This device integrates an audio mounting bracket, an Emergency Audio Evacuation Controller (EAEC) card, an enclosure, and a paging microphone to provide comprehensive control and communication capabilities.

Function Description

The VM-PMI serves as the central interface for managing paging and emergency communications within a system. It enables the activation and deactivation of pages to various areas, including all areas, areas not receiving EVAC or Alert messages, areas currently receiving EVAC messages, and areas currently receiving Alert messages. It also facilitates remote firefighter telephone communication by allowing activation/deactivation of the paging channel and silencing call-in request buzzers.

Important Technical Specifications

• Voltage: The device operates on 24 VDC.
• Current Consumption:
  • Standby: 23 mA
  • Alarm: 29 mA
• Remote Microphone Input: This input is isolated and supervised, ensuring reliable and safe operation.
• AUX Input:
  • Impedance: 1 kΩ
  • Level: 0.2 VRMS to 1.0 VRMS
  • Frequency Response: 100 Hz to 4 kHz
• Ground Fault Impedance: 10 kΩ
• Wire Size: Supports 18 to 12 AWG (2.5 to 1.0 mm²) wiring.
• Audio Channels: Capable of handling 4 simultaneous audio channels.
• Audio Inputs:
  • Local microphone: Isolated and supervised.
  • Remote microphone: Isolated and supervised.
  • Firefighter telephone: Isolated and supervised.
  • Remote audio: Isolated and supervised.
• Messages:
  • Storage: 2 minutes
  • Length: 39 seconds maximum
• Operating Environment:
  • Temperature: 32 to 120°F (0 to 49°C)
  • Relative Humidity: 0 to 93% noncondensing

Usage Features

The VM-PMI offers several user-friendly features for effective communication management:

• Paging Volume Indicator: Displays the relative signal strength during an active page, allowing operators to monitor audio levels.
• Ready To Page Indicator: Flashes during the preannouncement tone and remains steady when the system is ready to page, providing clear status feedback.
• Paging Microphone Controls:
  • All Call: Activates/deactivates paging to all areas.
  • All Call Minus: Activates/deactivates paging to areas not currently receiving EVAC or Alert messages.
  • Page To Evac: Activates/deactivates paging to areas currently receiving an EVAC message.
  • Page To Alert: Activates/deactivates paging to areas currently receiving an Alert message.
• Firefighter Phone Controls:
  • Page By Phone: Activates/deactivates remote firefighter telephone to the paging channel.
  • Buzzer Silence: Silences the call-in request buzzer, reducing distractions.
• Language Kit Support: A separately ordered VM-PMI-LK Language Kit is available to change control and indicator labels, allowing for localization and ease of use in diverse environments.

Maintenance Features

Installation and maintenance of the VM-PMI require adherence to specific safety and handling procedures:

• Safety Warning: Prior to installation or removal of equipment, it is crucial to remove all sources of power and allow stored energy to discharge to prevent electrocution.
• ESD Handling: Circuit boards are sensitive to electrostatic discharge (ESD), so proper ESD handling procedures must be followed to avoid damage.
• Wiring Supervision: All wiring is supervised and power-limited, enhancing system reliability and safety.
• Wiring Separation: A minimum separation of 0.25 inches (6 mm) must be maintained between power-limited and nonpower-limited wiring. Nonpower-limited wiring should be secured within the shaded area of the cabinet using nylon cable ties.
• Remote Microphone Wiring: Wiring from a remote microphone must be shielded and enclosed in conduit, following instructions in the VM-REMICA Remote Paging Microphone Installation Sheet (P/N 3101795-EN).
• Modular Design: The system's components, such as the EAEC card and audio enclosure, are designed for straightforward installation and connection using ribbon cables and mounting brackets, simplifying maintenance and upgrades.
• UL 864 Listed Equipment: The VM-PMI is designed to be used with UL 864 Listed equipment with compatible ratings, ensuring compliance with safety standards.

The VM-PMI Paging Microphone Interface is a robust and versatile solution for managing emergency and routine communications, designed with both functionality and safety in mind.
