Introduction
The information contained in this Installation and Operation Maintenance Manual, pertains only to the Alert-3
microprocessor based digital LCD alarm. This product will perform to conformity with the descriptions
contained in this manual, when assembled, operated, maintained and serviced in accordance with the installation
instructions provided.
The alarm must be checked periodically. Parts that are broken, missing, worn, distorted or contaminated,
must be replaced immediately. Should such repair or replacement become necessary, please contact Amico
Corporation or their distributors.
All alarms should not be repaired, or altered without prior written or verbal approval from Amico Corporation
or its distributors. Failure to comply will void all warranty on the alarm.
Statements in this manual preceded by the words WARNING, CAUTION, DANGER and NOTE are of special
signicance. Please read these sections carefully.
The Amico Medical Gas LCD alarm system (Alert-3) incorporates the latest microprocessor based technology
for alarm and surveillance systems. The alarm has been designed to provide user exibility and reliability. This
manual shall enable the customer to install, use, and maintain the alarm appropriately.
There is one “MUTE” ( ) or “PUSH TO TEST” button located on the front face of the LCD panel. The button
has two functions, to silence an alarm that has occurred, and to view the audible alarm sound level and high and
low set points. When an audible alarm is triggered, press the button to silence the alarm. To view the audible alarm
sound level and high and low set points, press and hold the button for 20 seconds to display the information on the
LCD Alarm screen.
All Gases or Vacuums are displayed on the LCD screen for clear visibility, to facilitate the monitoring function by hospital
personnel. Under normal operation, the gas indicator will be in the GREEN - OK position. If an alarm condition occurs, a RED-
Alarm indicator will be displayed and an audible alarm shall be continuous until silenced by pushing the“MUTE”button.
The LCD Alarm can be connected to a “Building Management System” for a generic alarm indicator.
WARNING: denotes steps which can prevent injury.
CAUTION: denotes steps which can prevent damage
to equipment.
DANGER: denotes steps which can prevent electrical
shock to equipment or to prevent serious injury and/
or death.

SHIPMENT DETAILS
When you receive an Alert-3 LCD series alarm from Amico Corporation, the package will consist of three main
sections; the Alarm Back Box, Sensors and the Frame/Module Assembly.
THE ALARM BACK BOX
The Alarm Back Box contains the auto-switchable System Power Supply with an ON/OFF switch, a built-in fuse and
terminal blocks (115 to 220 VAC - 50 to 60 Hz). The back box also incorporates the pipe stubs for applications
that require locally (in box) mounted sensors.
THE FRAME/MODULE ASSEMBLY
The Frame/Module Assembly consists of the frame and the LCD module. The hinged frame is designed to swing
down from the back box to facilitate installation and servicing of the alarm. This design will reduce installation
time and eliminate the risk of improper installation since all the modules are connected and tested at the factory.

6Amico Pipeline
Description of Modules
The Alert-3 LCD Alarm is a high technology microprocessor based module:
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 LCD. 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 module. The System Power Supply can be
easily removed and reinstalled by unscrewing it from the back box.
LCD MODULE
The LCD Module contains the LCD screen, microprocessor, buzzer, and the “MUTE” buttons. The function of
the “MUTE” button is to silence an alarm that has occurred. By holding the “MUTE” button for 15 seconds, the
module will display the high and low pressure set points. 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 applica-
tions requiring a remote audible alarm or a Building Management System.
SENSOR MODULE
The Sensor Module contains the transducer which converts the source of the pressure/vacuum into a digital
signal that is displayed on the LCD module. The sensor module shall be housed in an anodized aluminum and
nickel-plated brass enclosure to act as an interference barrier and it is temperature compensated. Each sensor
is clearly labelled 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 computer for the specic gas shown on the sensor housing.

Installation Guide
Install the back-box to the studs of the wall at the desired height. Ensure that the box is securely in place.
The mounting brackets are adjustable to suit the thickness of the wall. MAKE SURE the box is parallel, squared
and ush with the nished wall surface, to ensure that the frame assembly will t properly.
THE ALARM BOX
If the sensors are to be mounted locally (inside the back box), the pipe stubs must be connected to the
pipeline. Using silver-brazing techniques, connect each pipe stub to it’s 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 the lower portion of the copper pipe. When the brazing of pipe stubs has
been completed, the system can be pressure tested.
FOR LOCAL SENSOR ONLY
Perform a standing pressure test on the piping system as per NFPA-99 “Health Care Facilities”. Inspect all
joints for leaks and make certain each gas is piped to a correspondingly labelled gas service.
STANDING PRESSURE TEST
LOCAL (inside the back box)
Locate the gas specic sensor module to be installed.
In the back box, there are colour coded gas labels located under the DISS
Demand Check Valves. Each label identies where each sensor module
is to be placed.
The sensor module contains a gas specic DISS tting. Push the sensor
module hex-nut and nipple adapter up into the demand check-valve.
With a wrench, tighten the nut so that it makes a good seal.
Note: Pressure on sensors are not to exceed 250 psi for pressure sensors and
30 inHg for vacuum sensors.

Programming Gas Locations
1. Use the Notepad program to enter information for gas location. Each line can hold up to a maximum of 16
characters.
2. Two lines may be used per individual gas
3. The order of the text must go in order of gas; meaning the rst two lines of text shall represent the 1st gas
location, the next two lines of text shall represent the 2nd gas location, and so forth.
* Please refer to the diagram in the Installation Guide under section 7a (on page 9) to determine gas location on
the LCD Alarm screen.
4. Once all the text has been inputted, save the le on to the SD Card with the le name; location.
5. Insert the SD Card into the SD Card Slot on the LCD Alarm board (Refer to page 20 Appendix A).
6. While the LCD Alarm is on; press the reset button, then press and hold the setup button until the information
from the le saved on the SD Card (location.txt) appears on the LCD Alarm Screen.
* If the gas location text does not appear on the screen, repeat step #6. If the problem persists, contact Amico
Corporation for further assistance
7. Once the text is visible on the LCD Alarm screen, leave the SD Card in the slot for approximately 1 minute
in order for the information to be completely uploaded onto the alarm, and then proceed to remove the card.
8. Once the card has been removed, restart the LCD Alarm to ensure that the locations have been saved onto
the LCD Alarm.
* NOTE: Only capital letters and spaces will be displayed on screen, small caps, symbols and special characters
cannot be displayed.
Programming of the gas location is only available for V864 and up. If gas location is required, a new
front frame assembly is required; part number A3P-FRMASS-LCD
