Phone Jack
Connect the IMS-4000’s Phone jack to a standard 2-wire analog phone line. The unit dials using
touch-tones, with loop start only. The IMS-4000 will recognize ringer frequencies from 16 to 60 Hz
and will operate with all standard analog telephone systems that accept tone dialing.
Certain private telephone systems and public switching equipment may not accept the unit’s dialing
or may generate an unacceptable ring signal. In those cases, a dedicated line may be required for
the unit. Consult the supplier of your telephone system if you encounter problems.
CAUTION : Never install telephone wiring during a lightning storm. Never install telephone
jacks in wet locations unless the jack is specifically designed for wet locations. Never touch
uninsulated telephone wires or terminals unless the telephone line has been disconnected at the
network interface. Use caution when installing or modifying telephone lines.
Sensor Inputs
The sensor inputs are designed to interface with IMS-4000 series sensors ( See Chapter 6 ). The use
of RJ-45 jacks for sensor inputs allows the use of existing structured cabling to connect remote sen-
sors.
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.
Sensor

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: OFF
Red: OFF
Mode 1: Sensor present—No alarms
Green: ON
Red: OFF
Mode 2: Alarm detected but has not exceeded recognition time
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
