1.5 Alarm Configurations
All MEGA3 alarm panels are factory pre- con-
figured. Configuration of alarm panel varies
dependent upon customer’s requirements.
Three types of alarm panels are available.
• Master alarms
• Area alarms
• Combination alarms
1.5.1 Master Alarms
Master alarm panels include the following
modular components:
• Signal input boards (B10, B11) that can
accept 20 signals per board; maximum of
2 boards.
• Relay boards (B40, B41, B42, B43) that
can be used to control 16 dry-contact sig-
nals per board; maximum of 4 boards.
Master alarm panels can monitor 20 or 40
switched inputs.
Inputs can be assigned to any gas service
indicators.
1.5.2 Area Alarms
Area alarm panels include the following mod-
ular components:
• Gas Sensor input board (B60) that can be
used for up to 8 digital gas sensors.
• Digital gas sensor assembly, can be
mounted locally in the rough-in box, re-
motely on the gas pipeline, or in a com-
patible BeaconMedæs Zone Valve Box.
Maximum of 8 digital gas sensor assem-
blies per area alarm panel.
Area alarm panels may be configured for 1 to
8 gas inputs. If alarm is configured with gas
inputs, the sensors will be included for con-
nection to pressure/vacuum pipeline.
Sensors may be located inside the alarm
rough-in (local sensors) utilizing the DISS
inlet tube assemblies provided for brazing to
the hospital pipelines.
