Introduction
The Amico Automatic Gas Manifold is designed to provide a reliable, uninterrupted supply of gas to a hospital or
other medical facility. The manifold utilizes multiple high-pressure cylinders divided into two equal banks. One bank is
designated as a “Primary” source of gas while the other bank stands in reserve as a “Secondary” source.
A display of LED’s on the front of the manifold indicates the status of the gas supply. Each bank has a Green (IN USE),
Yellow (READY) and Red (EMPTY) LED. When the primary bank of cylinders is depleted, the manifold will automatically
switch to the secondary bank of cylinders without interruption of gas flow to the facility. The Red LED will illuminate
when a bank is depleted and two normally closed dry contacts for the reserve In-Use alarm will open. One or both sets
of contacts may be wired to an external alarm, remote buzzer and/or a building management system.
When replacement cylinders are attached to the depleted bank, the Red LED goes out and the Yellow LED illuminates
indicating that the bank has been automatically designated as the secondary supply. No other user interaction is
required. Both sets of dry contacts close to cancel any external alarm condition.
The power supply is connected to the top right-hand corner of the manifold. Connections from the manifold to the
Amico Master Alarm must be made from terminals marked C/Signal to the appropriate terminals (Reserve In-Use) on
the Master Alarm or a remote buzzer.
The enclosure for the manifold is NEMA-1 (general purpose applications only) and it is not recommended to be
mounted outdoors.
The manifold has a removable front cabinet. The pre-assembled circuit board is mounted directly to the back plate of
the manifold. This design will reduce installation time and eliminate the risk of improper installation, since each of the
components of the manifold are connected and tested at the factory.
FEATURES INCLUDE:
• Input power to the manifold is 110- 240 VAC, 50-60 Hz
• Incorporates six LED’s display - readable in poor lighting conditions
• Dual line Pressure regulators
• CRN type relief valves
• Wall mounting bracket attached to manifold for easy installation
• Manifold complies with CSA code
