NODE INSTALLATION & CONFIGURATION
Physical Description
The IMS-4000 Node is housed in a 9.6"w x 1.75"h x 7"d enclosure, which is 1 EIA rack-mount
space high.
Front Panel Layout
The front panel contains connections for eight sensor inputs, microphone input, Ethernet port, serial
port, and power LED. See figure below:

Sensor Inputs
The sensor inputs are designed to interface with IMS-4000 series sensors ( See Chapter 7 ). The use of
RJ-45 jacks for sensor inputs allows the use of existing structured cabling to connect remote sensors.
Microphone
The Node unit comes with a built-in microphone. Directly below the built-in mic is a separate jack
for connecting an optional condenser microphone to sense audible alarms, such as smoke detectors.
When an external microphone is connected, the internal microphone is disabled.
RJ-45 10/100BASE-T Ethernet Port
This jack is for connecting to your network so that the IMS-4000 Node can communicate with the
IMS-4000 Host and ping selected network servers and/or services. Two LEDs indicate Link Status
(left) and Receive Date status (right).
Serial Port
The RS-232 serial port is used to configure network settings. The port is DB9 male DTE and oper -
ates at 9600 baud, no parity, and 1 stop bit. A DB9 female–female null modem cable is required to
configure network settings.
ON/OFF Switch
The on/off switch connects main power and battery power to the system. In the event that main
power fails, the backup battery system will automatically power the system.
