CONTROL BUTTONS
There are two buttons located on the front face of the manifold and on the remote alarm.
They are the Mute and Stand-By buttons.
MUTE:
The Mute button will silence any alarms until the manifold returns to a Normal condition. After
the Mute button has been pressed, the visual alarms (LED's) will remain lit until the manifold returns to a
Normal condition. The alarm will sound again if another alarm occurs. The alarm will not be cleared until
the condition has been corrected.
The Mute button also serves as a test button. If the Mute button is held for 5 seconds, the manifold will
run through a self-diagnostic test and return to the current status.
STAND-BY:
By pressing and holding the Stand-By button for five seconds, the manifold will go into
stand-by mode, restricting the flow of both gases via the internal solenoids. As per NFPA 99, 2012
5.3.6.19.4: “it shall be mandatory that cylinder shut off valves be closed whenever the system is not in
use.” This ensures that a dangerous condition will not occur if the lines are left open. Simply press the
Stand-By button to return the manifold to full operation.
NOTE:
If equipment in the operating room has not been fully closed while in stand-by mode, the line
pressure will deplete. An initial alarm may occur immediately after returning the manifold into service.
Once pressures have been re-established, all alarms should clear.
CHECK VALVES
The manifold is equipped with internal check valves to avoid gas migration from the left side to the right side
and vice versa. Check valves are located immediately after the solenoids.
REMOTE ALARM/CONTROLLER
The Remote Alarm/Controller (RAC) is intended to relay information from the manifold room to an area of
the office that is consistently monitored. The RAC relays vital manifold information, including high/low line
pressures and reserve cylinder status. The RAC will also allow the facility to place the unit in temporary
stand-by mode, as well as mute any alarms. The RAC contains a speaker that provides an auditory signal
when the system is in alarm mode.
