INPUTS [5]
Express II comes standard with 8 universal inputs.
The input capacity may be expanded up to a total
of 40 universal channels. The following parameters
determine how each input functions. The parameters
apply to both the standard and expanded inputs.
1. Enable/Disable Inputs—This function allows you
to enable or disable an alarm on an input to cause a
dial out. An enabled input will respond to an alarm
and allow dial out. A disabled input will not initiate a
dial out if an alarm occurs. The default setting for all
inputs is
enabled.
2. Input Type—Express II’s inputs are universal
inputs. This means that they may be configured to
accept the following type sensors:
1 = Normally closed dry contact (digital)
2 = Normally open dry contact (digital)
3 = Pulse count (counts to 65,535 then resets to zero)
4 = 4–20 mA (analog)
5 = 0–5 Volts (analog)
6 = Temperature (thermistor):
1) 2.8K F thermistor (analog)
2) 2.8K C thermistor (analog)
3) 10K F thermistor (analog)
4) 10K C thermistor (analog)
7 = Time accumulator
The default input type is 2 (normally open dry
contact)
3. Input Recognition Time—The input recognition
time is the length of time an input must have an
alarm continuously before Express II will recognize
the condition. If an alarm is tripped and then clears
within the recognition time, it is not recognized as a
valid alarm. Express II will not dial out. This feature
is useful to prevent dial outs for momentary blips
or on self-correcting equipment. Each input can be
programmed with a different recognition time. You
may program the recognition time from 0 seconds to
12 hours. The default is
3 seconds.

INPUT PARAMETERS
The first step in programming the
INPUT parameters is to enter the
number of the input for which you
intend to program.
1) Press Program.
2) Press Input.
3) Press the input number (1-40).
Press Enter.
The Input menu will then appear on
the local display.
1-Enable/Disable Inputs:
1) At the Input menu, select Enable/
disable by pressing 1 on the keypad.
Or, by pressing arrow keys until the “>”
symbol, on the local display, is next to
Enable/disable.
2) Press 1 to disable.
Press 2 to enable.
2-Input Type:
1) Press 2 at the Input menu, to select
Input Type.(or on local display as
described in Enable/disable inputs)
A list of Input Types will then appear
on the local display.
