9.5 Setup System - Setup Sensor
The Universal Monitor has four analog sensor input points that may be configured individually. The
panel monitors connected equipment for any 4-20 mA input—for example, temperature and humidity.
To configure a sensor:
Log In and Choose Setup System
• From the Main Menu, use the arrows ↑ ↓ to choose System and
Control, then press Enter ↵ (see 9.1 - Login for help).
• Enter your password at the Login screen.
• From the System and Control Menu, use the arrows
↑ ↓ to choose
Setup System, then press Enter ↵ .
Select a Sensor to Configure
• From the Setup System Menu, shown at right, use the arrows ↑ ↓
to choose Setup Sensor and press Enter ↵ .
• From the Select Sensor Menu, choose the sensor you want—for
example, Sensor_1—and press Enter ↵ .
Table 22 shows sensor features that may be changed, along with the
default settings. By default, sensor inputs are not connected.
To activate a sensor input, you must specify it as connected and enter
corresponding values for 4 and 20 mA, as well as high and low set-
points. Other features that may be altered include the name of the sensor, the abbreviation for the
units, and defining the sensor as alarmable or as an event.
• Alarmable sensors may be Latched (Y) or Unlatched (N).
• Event status allows you to monitor a sensor’s high and low setpoints—and use those setpoints to
change the status of an output, if desired—without triggering an alarm. Events are always
Unlatched.
• You may also specify a time delay before the Universal Monitor responds to an alarm or event.
Use the steps following Table 22 to change the default settings for any analog sensor input.

CONNECTED* N (Not connected)* Y (Connected)**
LABEL SENSOR_1 Any name (up to eight characters)
UNITS Blank Any units (up to three characters)
4 mA -999.9 Can define up to two decimal places—for example, -99.99
20 mA +999.9 Can define up to two decimal places—for example, +99.99
OFFSET +000.0 Can define up to two decimal places—for example, +00.00
ALARM/EVENT AL (Alarmable) EV (Event)
LATCHED N (Unlatched) Y (Latched)
LOW SETPT -0999.9 Can define up to two decimal places—for example, -999.99
HIGH SETPT +0999.9 Can define up to two decimal places—for example, +999.99
SENSOR DELAY 00:01 (1 second) Any time (in minutes and seconds) from 00:00 to 99:59
* If a sensor is configured as N (Not connected), the display will show an empty reading (blank spaces).
** If a sensor is configured as Y (Connected) and is functioning properly, the display will show a reading. If the
connected sensor is not functioning properly, the display will show dashes (------) indicating a problem.
