Introduction

The Alarm Valve Combo Unit is a 2 in 1 design, which combines the Area Alarm and Zone Valve Box, to
compensate for space restrictions.

Amico Shuto Valves are used to stop the ow of medical gas or vacuum in the medical gas distribution
pipeline in cases of emergency or maintenance.

Valve Boxes must be installed to enclose the shuto valves when the valves are located in areas accessible to
unauthorized personnel.

The Amico medical gas Alarm Valve Combo Unit incorporates the latest microprocessor technology for alarm
and surveillance systems. The alarm has been designed to provide user exibility and reliability. This manual
will enable the customer to install, use and maintain the alarm properly.

All gases or vacuum are displayed with large red LED’s for clear visibility. To facilitate the monitoring function
by hospital personnel, a trend bar is provided to show the direction of the gas/vacuum pressure. Under normal
operation, the gas trend indicator will be in the GREEN - OK position. If the gas pressure approaches alarm
condition, the trend indicator will display a RED - Caution indicator. If an alarm condition occurs, the buzzer will
sound.

Features

• Individual microprocessor on each display and sensor module.

• Gas specic sensors can be mounted locally or remotely, up to 2,500 feet (750 m), utilizing 22 gauge
shielded twisted pair (2 shielded wires).

• The DISS gas specic sensor is housed in a tamper-proof enclosure. The Sensor Module is housed in
an anodized aluminum and nickle-plated brass enclosure to act as an interference barrier.

• The Sensor Module is the smallest, computer-calibrated and temperature-compensated sensor in the
industry.

• True digital LED display and trend indicator for each service monitored.

• Illuminated LED display that is visible at an angle or in dim lighting conditions.

• PSI, kPa or BAR display (switch selected).

• Self-diagnostic circuitry with error display for problem identication.

• Highly accurate solid state pressure piezoresistive transducer.

• Adjustable repeat alarm (1 to 60 minutes or o).

• Dry contacts for remote monitoring of High and Low alarm status.

• Modules are factory mounted on a hinged frame assembly for ease of installation and maintenance.

• Field programmable push buttons for adjustment of HI and LOW set-points on display module.

• Available in 1 to 7 display modules.

• Built-in relay for remote annunciator applications.

Installation of Alarm Valve Combo Unit Boxes

The Amico Valve Combo Unit is shipped in one container holding two separate packages. One package
contains the Alarm Valve Combo. The other package contains the window and the frame assembly.

1. Recessed Valve Box: anchor the valve box rough-in to the studs so that the front edge will be ush or
slightly recessed with the nished wall. The recommended mounting is 66" (1676 mm) from the top of
the valve box to the nished oor.

NOTE: The Shuto Valve handles should be installed to point downstream for pressurized gases.

2. Before brazing, remove all box plugs as they could melt during brazing. Wrap wet rags around the tube
extensions next to the valves to prevent overheating and possible damage to the valve seals. Connect
copper tubing to the valve extensions (outside the valve box) using brazing methods and materials in
accordance with NFPA-99 or CSA Z7396.1-06. Once valve extensions are cool, remove rags.

3. Test the system (per appropriate standards) to ensure that the intended gas and vacuum services are
connected to the appropriate lines.

WARNING: Misconnection of the gases could lead to serious or fatal injury to patients. Following the
initial installation of shuto valves, make certain that the intended services are correctly connected to
the appropriate service lines.

4. Test the system for leaks (per appropriate standards)

NOTE: Pipe sealants should comply with the requirements of NFPA 99
or CSA Z7396.1-06. Use care to exclude pipe sealants from the valve
cavity and from interior tube surfaces exposed to medical gas ow or
vacuum service. Properly applied Teon tape is an alternative to pipe
sealants. Check Shuto Valve handle operation for proper clearance
from gauge (if installed).

5. After the wall is nished, remove the window by pulling the ring
towards you and attach the aluminum frame to the alarm valve
combo unit valve box with the No. 6 metal screws provided. Then put
the window back in place.

6 Amico Pipeline

Maintenance

Operate shuto valves periodically and repair them, if seals tend to stick or leak. Notify all concerned
personnel before shutting o any gas supply.

WARNING: To protect the lives of patients, always notify the appropriate medical facility sta before
shutting o the supply of medical gas or vacuum through a shuto valve. Do not close shuto valves
except in cases of emergency or maintenance.

Clean the exterior of the valve boxes routinely with soap and water. Strong solvents may damage the Lexan
window.

Authorized hospital personnel should close shuto valves in the event of re, explosion or damage to the
pipeline systems or equipment.

In Alarm Valve Combo Unit boxes, the Shuto Valve handles become accessible after the window has been
removed from the valve box.

To remove the window, grasp the ring and pull outwards. Turn valve handle towards you to shut o the
ow of gas or vacuum.

Zone Valves have a swingout design body which makes changing the internal components of the ball
valve easier.

All valve bodies can be accessed by loosening all bolts and nuts and removing only one bolt, at this point the
valve body can be swung out for servicing.

Description of Modules: Common to All Alarms

System Power Supply

The System Power Supply has been pre-installed into the back box assembly. The System Power Supply
converts the AC voltage supply to the alarm into two voltages: 5 VDC (regulated) required by the
microprocessor hardware and 15 VDC (unregulated) required by the buzzer and the LED’s. This unit also
contains the main ON/OFF power switch, the transformer, the heat sink, the main fuse and fuse cover, the
rectifying circuitry, the terminal blocks and the low voltage DC power cable for connecting this unit to the
annunciator module. The System Power Supply can be easily removed and reinstalled by unscrewing it from
the back box.

Annunciator Module

The Annunciator Module contains the buzzer, a “Power On” LED as well as the “TEST” and
“ALARM MUTE” buttons. The function of the “TEST” button is to verify that the buzzer and
all the LED’s are in working condition. An alarm will be heard when this button is pushed
and all the LED’s will light up. When the button is released, the alarm will silence. The
“ALARM MUTE” button is used to silence an alarm that has occurred. This module also
contains a fail-safe relay that de-energizes when the buzzer is activated. This relay can be
used with the Amico remote buzzer, for applications requiring a remote audible alarm
(see Appendix B), for connection to another Amico alarm or a building management
system.

Alarm Valve Display Module

The module provides a digital display of the actual pressure/vacuum of a gas being
monitored. In addition, a gas trend indicator bar with High and Low alarms are displayed.
The trend bar has two coloured LED’s: GREEN for Normal and RED for High and Low
conditions.

Each display module contains a gas specic, colour coded label (USA or ISO colours are
available). The Display Module is eld adjustable for pressure/vacuum settings, repeat
alarm and unit of measure. Dry contacts for high and low alarms are available for remote
monitoring of each module.

Sensor Module

The Sensor Module contains the transducer which converts the gas/vacuum pressure
source into a digital signal that is displayed on the display module. The sensor module
shall be housed in an anodized aluminum and nickel-plated brass enclosure to act as an
interference barrier. It is also temperature compensated.

Each sensor is clearly labeled and colour coded for the gas or vacuum being monitored.
The sensor module contains a gas specic DISS tting to ensure correct connection of
the proper sensor to the respective gas. Each sensor has been factory calibrated by a
computer for the specic gas shown on the sensor housing. If it is not connected to the
appropriate gas display module, an error message (EO2) will be displayed.

Installation of Alarm

For Local Sensor Only

If the sensors are to be mounted locally (inside the valve box), the pipe stubs must be connected to the
pipeline. Using silver-brazing techniques, connect each pipe stub to its appropriate gas or vacuum while
ensuring that the bottom of the pipe stub is wrapped with a damp cloth. BE CAREFUL not to damage the DISS
check-valve by overheating. When the brazing of pipe stubs has been completed, the system can be pressure
tested.

Standing Pressure Test

Perform a standing pressure test on the piping system as per NFPA-99 “Health Care Facilities” or
CSA-Z305.1 “Non-ammable Medical Gas Piping Systems”. Inspect all joints for leaks and make certain each gas
is piped to a correspondingly labeled gas service.

• Example: English, 3 valves, 1/2" Oxygen, 3/4" Medical Air and 1-1/4" Medical Vacuum. Will be in a
4 gang box, not a 3 gang: AVCU3-05O05A12V

• The 1-1/2" valve will have an empty space above the valve.

• Example: a box with a 1/2" Oxygen, 3/4" Medical Air and 1-1/2" Medical Vacuum and a power
supply will require a 5 gang box not a 4 gang box.

• The 2" valve will be assembled in a 6-1/2" deep box and shall accommodate up to a maximum of four
gases. The 2" valve shall be positioned on the bottom of the assembly. The height measurements
of the 6-1/2" deep valve box are the same as the 3-7/8" deep valve box. When comparing height
measurements, consider the gap above the 2" valve.

• Example: a valve box with 1/2" valve, 2" valve and a power supply would be in a 3 gang, 6-1/2"
deep box, which would be the same height as the 4 gang, 3-7/8" valve box.

• 2-1/2" and 3" valve assemblies are only oered as singles.

# of valves:

1 = 1 Valve

2 = 2 Valves

3 = 3 Valves

O = Oxygen

A = Medical Air

V = MedVac

2 = Nitrous Oxide

N = Nitrogen

C = Carbon Dioxide
