P/N 3101890-EN • REV 006 • ISS 21JUN18 9
Description
Electronics Chassis: Provides the mounting, internal power, and audio and data
distribution for the main board, user interface, and supporting cards. Includes a
preinstalled VM-CPU Main Board, VM-LCD User Interface and three blank filler plates.
Installs on the backbox. See installation sheet P/N 3101780-EN for specifications.
The preinstalled VM-CPU processes all information from modules installed in the same
cabinet and from other control panels on the VM-1 life safety network. The VM-CPU
provides common relay outputs, two signaling line circuits (loops), network data and
digital audio risers, panel programming inputs, and connection to R-Series or K-R-Series
remote annunciators. One VM-SLC signaling line circuit c
ard is preinstalled on the board.
See installation sheet P/N 3101798-EN for specifications.
The preinstalled VM-LCD provides the user interface for the fire alarm control panel.
installation sheet P/N 3101781-EN for specifications.
The preinstalled filler plates can be replaced with up to three D12LS-VM Control-
Indicating modules.
(G/R) Cabinet door: Provides two viewing windows and is secured with a key lock. See
installation sheet P/N 3101779-EN for specifications.
Control panel options
Note: Option cards and modules are ordered separately and installed in the field.
Table 3: Control panel option cards
Description
-PS10 Class A Adapter Card: Converts the Class B notification appliance/auxiliary power
circuits on the PS10-4B Power Supply Card to Class A notification appliance circuits.
Installs on the PS10-4B. See installation sheet P/N 3101776-EN for specifications.
-NOC RS-485 Network Option Card: Provides the interface for both the network data riser and
a digital audio riser. Provides connection to other VM-1 control panels to form an VM-1
life safety network (24-node max.). Installs on the VM-CPU. See installation sheet P/N
3101782-EN for specifications.
-SLC Signaling Line Circuit Card: Provides a Class B, Class A, or Class X signaling line circuit
and resettable 24 VDC for powering conventional two-wire smoke detector circuits on
VM-1 compatible modules. Installs on the VM-CPU. See installation sheet P/N 3101785-
EN for specifications.
-SLC-HC Signaling Line Circuit Card: Optional replacement card for the VM-SLC for installations
where the signaling line circuit has more than 90 isolators and isolator bases (with
V-Series sensors installed). Provides a Class B, Class A, or Class X signaling line circuit
and resettable 24 VDC for powering conventional two-wire smoke detector circuits on
GSA modules. Installs on the VM-CPU. See installation sheet P/N 3102327-EN for
specifications.
-SLCXB Signaling Line Circuit Expansion Card: Provides up to two Class B, Class A, or Class X
signaling line circuits and resettable 24 VDC for powering conventional two-wire smoke
detector circuits on VM-1 compatible modules. One VM-SLC signaling line circuit card is
preinstalled on the VM-SLCXB. A second SLC card must be added to provide the
additional device loop. Installs on the VM-ELEC electronics chassis. See installation
sheet P/N 3102128-EN for specifications.
