SCM-NM
RS485 Network
The SMART Connect Multi-
loop system network has the
facility to monitor, indicate
and control the functions of a
fire alarm installation, thus
allowing signals to be
distributed around a large
site. The network will
accommodate up to 64
nodes. The network uses
RS485 data communication.
Communication Protocol: RS485
Maximum Network Size: 64 Nodes
Maximum Distance Between Nodes: 1KM (using a
screened data cable) or 100M (using a standard
fireproof cable)
Network Wiring Typologies: Bus or Ring
NOTE: Only 1 network module allowed per panel. If
a second module is fitted, it will be powered down
when the panel starts.
SCM-MIM
Multi Input Unit

to monitor and raise alarm
from any ancillary equipment
such as sprinkler flow switch,
aspiration detectors,
secondary fire control panel,
beam detectors, external
power supplies etc.

SCM-ZMM
Zone Monitor
A zone monitor that can be
typically used for
conventional devices and/or
for special detectors that are
not available in addressable
form. It has 6 x Class B input
circuits.

SCM-PM
RS232 Printer
The plug-in RS232 module
will give a Smart Connect
Multi-loop panel the ability to
interface to RS232 serial
equipment and devices. This
is most commonly used to
connect the panel to an
RS232 panel printer, or a
desktop printer for real time
event log printing. The
module also has a 5V aux
output that is used to provide
power to the panel’s internal
printer.
Communication Protocol: RS232
Baud Rate: 9600
Data Bits: 8
Parity: None
Stop Bits: 1
Compatible Devices: CUSTOM PLUS2 Panel Printer
