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.
Since the sensor produces an analog signal, it must connect directly to the Host or Node. The path
from the sensor to the IMS unit CANNOT pass through a network Hub or Switch.

Each sensor input has two LEDs (red and green) to indicate the present status of the input. The
key below describes the multiple modes of operation.
Mode 0: No sensor at input

Green: FAST BLINK
Red: FAST BLINK
Mode 3: New alarm exists and not yet acknowledged
Green: SLOW BLINK
Red: SLOW BLINK
Mode 4: Input is in normal range, but alarm is still unacknowledged
Green: ON
Red: SLOW BLINK
Mode 5: Alarm has been acknowledged, but input is still out of range
Green: SLOW BLINK
Red: ON
Mode 6: Sensor in trouble
Green: QUICK FLASH
Red: QUICK FLASH
AC Power and Battery LEDs
The AC Power and Battery alarm status is indicated by two red LEDs. Their modes of operation
are described below.
Mode 1: No Alarm
LED: OFF
Mode 2: Alarm detected but has not exceeded recognition time
LED: FAST BLINK
Mode 3: New Alarm exists and not yet acknowledged
LED: SLOW BLINK
Mode 4: Alarm has been acknowledged but input is still out of range
LED: ON
Microphone Jack
The Host 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.
