VM-LCD User Interface
The VM-LCD is an operator layer module that interfaces with the VM-CPU to provide indicators and user controls
for the control panel. Only one VM-LCD is required to provide a point of control for the entire network. Additional
user interfaces can be added to any VM-1 control panel in the VM-1 network to provide additional points of
control. See the VM-LCD User Interface Installation Sheet (P/N 3101781-EN) for installation instructions and
specifications.
D12LS-VM Control-Indicating modules
D12LS-VM Control-Indicating modules are operator layer modules that provide additional operator interface
capability. They can be mounted on any of the last three card addresses on the VM-ELEC chassis (see Figure 23
on page 82). See the D12LS-VM Control-Indicating Module Installation Sheet (P/N 3101793-EN) for installation
instructions and specifications.
Digital audio subsystem
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.
VM-PMI Paging Microphone Interface
The VM-PMI provides controls for emergency voice and alarm communications in the audio subsystem. The
interface is installed on the backbox, below the VM-ELEC assembly (see Figure 24 on page 84). It consists of an
audio mounting bracket, EAEC Emergency Audio Evacuation Controller card, audio enclosure, and paging
microphone. In the VM-CU, the VM-PMI is identified in the cabinet configuration as ASU, under Rail 2 Type
(Configure > Cabinet).
See “Digital audio subsystem” on page 60 for detailed information on the VM-PMI. See the VM-PMI Paging
Microphone Interface Installation Sheet (P/N 3101788-EN) for installation instructions and specifications.
VM-MFK Firefighter Telephone Kit
The VM-MFK Master Firefighters telephone provides two-way communication between firefighters in the building
and the Fire Command Center. You can also use the telephone handset as the paging microphone.
See “Digital audio subsystem” on page 60 for detailed information on the VM-PMI. See the VM-MFK Master
Firefighter Telephone Kit Installation Sheet (P/N 3101790-EN) for installation instructions and specifications.
