Configuring the NM-AIC-64, Contact Closure Network Module
Following are examples:
Point 57 is monitoring the ambient temperature of a building and the sensor range is –20 to 75 degrees
Celsius. Below 0 degrees is a critical alarm, 0 to 10 degrees is a major alarm, 10 to 35 degrees is the
normal range, 35 to 45 degrees is a minor alarm, and above 45 degrees is a major alarm. The
configuration for this point follows:
alarm 57
analog current-loop –20 0 10 35 45 75
level low-low 1
level low 2
level high 3
level high-high 2
Point 58 is monitoring a fuel tank level with a resistive sensor. Below –46 volts is a critical alarm,
–46 to –40 volts is a minor alarm, and above –40 volts is the normal range. This is a unidirectional alarm,
so the high thresholds are set equal to the high bound (since this threshold cannot be crossed). The
configuration for this point follows:
alarm 58
analog voltage –46 –40 60 60
level low-low 1
level low 3
Point 59 is monitoring a battery bank. Below –42 volts is a critical alarm and above –42 volts is the
normal range. The configuration for this point follows:
alarm 59
discrete voltage –42 high
level 1
Programming the Discrete Contact Points
The discrete alarms do not require as much programming as the analog alarms. The AIC CLI commands
available are the following:
Command
Description
no
Reversal option
exit
Exits current mode
description
Sets the description. If
no
is set, then the description
is not required.
normally
Sets the alarm’s normal state to closed. If the
no
option is used, the normal state is set to open. This
command applies only to points 1 - 56.
level
Sets the alarm’s level to the specified level.
