4.5 Setting Up a Combination Alarm
The combination alarm combines the func-
tionality of an area alarm and a master alarm.
It monitors two things:
• Gases and their pressures.
• Source equipment.
Two independent hard wired alarms monitor-
ing source equipment are required per facility
to meet the 24-hour monitoring requirement
in the NFPA 99 standard.
For convenience to the customer, the MEGA3
Medical Gas Alarm is shipped from the fac-
tory as a configured unit. However, the infor-
mation for the signals connected in the field
need to be entered into the alarm using the
touch screen interface.

• Follow the steps for configuring source
badges on a master alarm (section 4.4.1).
4.5.2 Configuring Gas Badges

es on an area alarm (section 4.3.1).
