Alarm System.
The Area alarms all begin with Gas #(1 thru 8) and the
Master alarms all begin with Badge #(1 thru 12).
The default Area alarms for each individual gas are as
follows:
• Sensor Mismatch Alarm
• High Setpoint Alarm
• Low Setpoint Alarm
• Sensor Missing
The Master alarm digital input signals are grouped
together under one gas badge and are indicated by
the source gas (these are edited in the “Master Alarm
Settings” screen).
Up to 7 digital input signals are available for each
badge, or piece of source equipment.
The Alarm Status screen has the same sorting ability
as the Alarm History screen – just press the sort button
in the upper left corner.
Alarm Summary
The Alarm Summary screen shows a list of all active
alarm conditions.
This screen is also accessible from the red bar with
the scrolling marquee at the bottom of the screen that
pops up during an alarm event. Press the “list” icon,
which is second from the left on the red bar.
Alarm conditions can be acknowledged and cleared
on this screen. Further details are given in the “Alarm
Event” section under “Operation.”
Gas Settings
This screen is only applicable to Area alarms and
Combo alarms.
In the gas settings page, you are able to change
the medical gas type, add/subtract a gas, designate
the location monitored for each gas, and manually
change the high/low alarm settings. NOTE: All Powerex
FirstCall™ Area Alarms are pre-programmed from the
factory with the correct medical gases and default high/
low alarm settings.
Location where each gas is being used can be entered
in this screen as well as via the home screen.
To edit/add/delete a gas badge, first press the edit
button next to the row number on the left. This makes
that row active in the editing row at the top highlighted
in yellow.
The gas is edited in the first column, and can be
selected from a preloaded list of NFPA 99 medical gases.
The correct NFPA 99 color combination is automatically
selected when a gas is selected.
