Description

 

 

 

 

Sensor Name

All

A name used to identify the sensor in the alarm system. Select a name

 

 

 

readily identified by the viewer. The sensor name is displayed on the

 

 

 

Main screen during a no-alarm condition and on the Alarm screen during

 

 

 

an alarm condition. Two name choice types are available:

 

 

 

• Common Name: These are preprogrammed names.

 

 

 

• Custom Name: This selection allows you to enter any name if the

 

 

 

preprogrammed common names do not adequately identify the sensor

 

 

 

in the system (limited to 16 characters).

 

 

 

 

Note: Duplicate sensor names are not permitted.

 

 

 

 

Unit of

 

• Blue, Red and White

This parameter allows you to choose the unit of measure used for sen-

sor reading and display.

 

 

 

4-20mA sensor

• Blue, Red and White temperature sensors: °C or °F

 

 

• Wireless

4-20mA sensors: the following Common Units of measure are

 

 

temperature sensors

available: F (Fahrenheit), C (Centigrade), K (Kelvin), % rh (percent

 

 

 

relative humidity), psi (pounds per square inch), Pa (Pascals), kPa

 

 

 

(kiloPascals), lb (pound), kg (kilogram)

 

 

 

 

4-20mA sensors can also use custom units. Enter the appropriate units

 

 

 

for the connected 4-20mA sensor via the keypad.

 

 

 

Resolution

4-20mA sensor

This determines the range that may be used for the 4-20mA sensor. The

 

 

 

full scale range is determined by the values entered in the Low Scaled

 

 

 

Value and the High Scaled Value. You must select the correct resolution

 

 

 

in order to set the true range limits for the 4-20mA sensor you are install-

 

 

 

ing. The available values are as follows:

Low Scaled

4-20mA sensor

This parameter equals the environmental reading that results in a sensor

Value

 

 

output of 4mA or its minimum valid reading. This is dependent on the

 

 

 

setting of the resolution as discussed above.

 

 

 

High Scaled

4-20mA sensor

This parameter equals the environmental reading that results in a sensor

Value

 

 

output of 20mA or its maximum valid reading. This is dependent on the

 

 

 

setting of the resolution as discussed above.

 

 

 

Hysteresis

• Blue, Red and White

The Hysteresis setting helps prevent alarms from being set and reset

 

 

temperature sensors

continually if the environment is at or near the alarm set point by provid-

 

 

HA-III+

ing an acceptable variance. For example, if Hysteresis is set at 2 and the

 

 

4-20mA sensor

sensor High limit is set at 50, the sensor reading must decrease to 48

 

 

 

(50 minus 2) in order for the alarm condition to reset to a no-alarm condi-

 

 

 

tion.

 

 

 

 

 

Low Alarm

• Blue, Red and White

The Low Alarm Limit sets the value that trips the low alarm when
