4.4 Setting Up a Master Alarm
The master alarm monitors whether source
equipment is working properly. Two indepen-
dent hard wired alarms are required per facil-
ity to meet the 24-hour monitoring require-
ment in the NFPA 99 standard.
The information for the signals connected in
the field needs to be entered into the alarm
using the touch screen interface.
To set up or change the configuration of an
alarm, follow the steps outlined in the initial
set-up for an unconfigured master alarm in
section 4.4.
