EQUIPMENT
**************************************************************************
NOTE: Edit alarm items to agree with appropriate
system design.
**************************************************************************
2.2.1
Alarms
Provide enameled steel of minimum 16 gage, NEMA ICS 6, modular, master
alarm panel for each appropriate medical and vacuum systems. Provide
service indicator lights and alarm signal testers. Provide alarm signal
testers with test buttons or switches to temporarily activate visual
signals and audible signals to test the system status.
2.2.1.1
"Reserve In-Use" Switchover Alarm
For medical gas cylinder manifold systems, provide alarm which activates
when any reserve medical gas supply goes into operation.
2.2.1.2
Pressure Alarms
For failure alarms for medical air compressors and vacuum pumps, provide
low and high pressure switches, of either contact or mercury (Hg) type, to
activate alarms when pressure either drops or rises. Set operating
pressure differentials at 21 kPa (gage) 3 psig minimum.
2.2.1.3
Dew Point Alarm (Medical Air System)
Provide local non-cancellable visual and cancellable audible alarm. This
alarm is activated by receiving signal from the dew point monitor, when the
pressure dew point rises above 6 degrees C at 690 kPa (gage) 42 degrees F
at 100 psig.
2.2.1.4
Air Filter Alarm (Medical Air Systems)
Provide differential pressure switch for the filter to activate an alarm
when pressure drop across the filter exceeds 14 kPa 2 psi over that when
the filter is new and clean.
