Product Description
Lifeline automatic changeover manifold system
is designed to provide a reliable, uninterrupted
supply of gas to a hospital or other medical facility.
A typical manifold system consists of a manifold
control panel with two banks. Liquid containers
are connected to left bank and high-pressure
cylinders are connected to right bank.
This type of manifold is often referred to as
“liquid x high-pressure” or “LQ x HP”. Left bank is
designated as "Primary" source of gas while right
bank stands in reserve as "Secondary" source.
Manifold control panel is connected to an
external high pressure reserve header assembly
consisting of multiple high-pressure cylinders.
Lights on front of manifold control panel and
power supply enclosure indicate status of gas
supply. Each manifold bank has a green (IN
USE), yellow (READY), and red (EMPTY) light.
The power supply enclosure has a red (RESERVE
IN USE) and red (RESERVE LOW) light.
When manifold’s primary bank of liquid
containers is depleted, system will automatically
switch to secondary bank of high-pressure
cylinders. When liquid containers are replenished,
manifold will automatically switch back to primary
(left) bank. If primary bank of liquid containers
and secondary bank of high-pressure cylinders
Statements in this manual preceded by
following words are of special significance.
WARNING:
Means there is a possibility
of injury or death to yourself or others.
CAUTION:
Means there is a possibility of
damage to unit or other property.

Introduction
are depleted, manifold system will automatically
switch to external high-pressure reserve header
assembly.
Normally-closed dry switch contacts are
supplied for each alarm condition listed below.
Switch contacts are typically wired to external
master alarm panels and will open when alarm
condition occurs.

An external power supply converts 120 VAC to
24 VAC to power manifold. Power supply is
connected to bottom of manifold control via a 48"
cable.
Lifeline manifold system is designed in
accordance with National Fire Protection
Association (NFPA) 99.
Definition of Statements
Environmental Considerations
Manifolds are to be installed in accordance with
requirements stated by NFPA 99, CGA and all
applicable local codes.
Manifold components are designed to work
best over a temperature range of 32° F (0° C)
through 130° F (54° C). Wider temperature
variations may cause manifold malfunctions to
occur.
BeaconMedæs recommends manifold control
panel be located with its power supply at an
installation site protected from moisture,
continuous exposure to direct sun rays, ice and
snow.
Installing a nitrous oxide or carbon dioxide
manifold and high-pressure reserve header
assembly in a location that exposes it to ambient
temperatures below 32° F (0° C) is not
recommended.
