INTRODUCTION
The Amico medical gas alarm system (ALERT-1) incorporates the latest digital technology in alarm
arid surveillance systems.
The system has been designed primarily for user flexibility and reliability.
•Digital read-out for every gas service measured.
•Bar-graph display for trend indication.
•HI/LOW alarm indication with adjustable repeat times.
•Interface to building management computer.
•Easily expandable for additional gas services.
• NO moving parts very reliable.
•Modular construction ease of maintenance.
•Plexiglass front covereasy to clean.
•Adjustable repeat alarm
Optional computer interface.
•Meets requirements of CSA 2305.1.
ALERT-1 is divided into four main modules which plug
into the alarm box.
1. POWER SUPPLY MODULE
This 'module converts the 115 VAC
supply voltage into 24 VDC required for
the alarm system and contains the
audible alarm and lamp test circuitry.
2. PRESSURE/VACUUM
DISPLAY MODULE
This module provides a digital display
of the actual pressure or vacuum of a
gas being monitored. In addition a gas
movement trend and HI/LOW alarm
section is provided for quick identifica-
tion.
3. SENSOR MODULE
This module contains the transducer
which converts the pressure (vacuum)
source into an electric signal that is
displayed by the pressure display
module.

4. MASTER STATUS MODULE
This module will continuously monitor up to 8
remote signals for operating alarms and
emergency alarms such as: pressure switches,
low liquid levels, high or low gas pressures,
etc. If any of the signals being monitored goes
into an alarm condition, a red light will come on
and an audible alarm will sound.

MASTER STATUS MODULE
ALERT-1 is factory-calibrated for"Normally Closed Circuit" (NC) operation so that the alarm function
will be initiated on an open circuit. In this mode the alarm system will signal both alarm conditions
and system malfunctions.

5. ALARM BOX
These modules are pluged into the
motherboard of the alarm box once
it has been installed in the wall.

TRANSFORMER
MOTHERBOARD
The box itself (Fig. 1), houses the pigtails that deliver the gases (vacuum) into the alarm and in
addition contains:
•transformer
•main fuse
•overload protection unit
•terminal block (115VAC)
•motherboard

INSTALLATION
A. BOX IN THE WALL
(MASTER STATUS & AREA ALARMS)
1. Remove the alarm box from the
shipping carton and install the box
securely in the roughed-in wall at the
appropriate place. The mounting brack-
ets are adjustable to suit the thickness
of the wall. Do not remove the Window
Frame or any Modules from the ship-
ping carton until the box is mounted in
the wall and all the plastering, external
wiring, and brazing of the copper pig-
tails is complete.
(AREA ALARMS ONLY)
2. Once the box is installed in the wall
remove the dust cover from the front.
Using silver-brazing techniques, con-
nect each pigtail to its appropriate gas
(Vacuum) while ensuring that the bot-
tom of the pigtail is wrapped with a
damp cloth so as not to damage the
check-valve inside the box. (Fig. 2)
The system can now be pressure tested.
B. MODULES
CAUTION
Fig. 2
The circuitry on ALERT-1 contains sophisticated integrated circuits and as such
can be damaged by static. When installing the modules, hold the boards by the
edges and do not touch any of the components or circuitry on the board. Static
discharge to a component can cause the module to malfunction. During the
installation of the modules, the supply (115 VAC) should not be connected.

POWER MODULE
1. POWER MODULE
(a) Remove the power module from its box by holding the metallic plate that covers the
circuit board.
(b) Plug the connector which is located at the end of the tail of the power module into the
first (leftmost) receptacle on the motherboard. Since the connector is keyed it should slide
into the receptacle easily. If resistance is encountered, it indicates the connector is not
being inserted the right way. Ensure that there are no pins visible on either end of the
motherboard connector.
(c) Flip the power module so that it hangs by its cable just below the box. The circuit with
all the components should now be visible.
(d) Bring the power lines which
protrude through the transformer
cover up to the female socket on
the power module and insert the
male plug into the female socket
as shown in Figure 3. The con-
nector is keyed and hence should
slide into the socket easily.
Fig. 3
(e) The audible alarm is equipped with a repeater function preset at a 30 minute interval,
but shipped disabled. If the repeater function is desired, move black "jumper" from "DIS"
(disable) position to "ENABLE" position, then adjust screw dial at the top of module to any
desired alarm repeat time between 30 and 2 minutes.

PRESSURE ANDSENSORMODULES
2. PRESSURE DISPLAY AND SENSOR MODULES
These two modules are installed concurrently. The sensor module contains the transducer which
is connected to the brass quick-disconnect.
SENSOR MODULE
NOTE: ALWAYS HOLD THIS MODULE
BY THE BRASS QUICK-DICONNECT
FITTING. (Fig. 4)
(a) Plug the brass male connector protruding
from the top of the sensor module into the
female receptacle in the box in the wall. The
connector should click into place. (Fig. 4)
(b) Remove the display module from its box
and plug the connector atthe end of the tail into
the appropriate connector on the motherboard
just below the sensor module. (Fig. 5)
(c) Flip the display module so that it hangs by
its cable just below the box. The circuit with all
the components should now be visible.
(d) Plug the small cable leading from the end
of the sensor module into terminal J2 on the
pressure display module. (Fig. 4)
(e) The unit has been factory calibrated and
requires no adjustments.

STATUS MODULE
3. STATUS MODULE
(a) Plug the connector at the end of the
tail of the Status module into the appro-
priate place on the motherboard.
(b) Flip the status module so that it
hangs by its cable just below the box.
The circuit with all the components
should now be visible.
(c) Connect the external switches to
the appropriate terminal blocks on strip
J4 as per the wiring diagram shown on
page 11.
4. COMPUTER INTERFACE
MODULE
The computer interface module is a
piggyback board that fits on top of the
status module and plugs into connector
(P1) located at the top of the status
board. (Fig. 7) Plug the module in (if it
is not already on) and attach the board
using the five screws provided. Con-
nect the module to the computer inter-
face as shown in the wiring diagram on
page 13.

NOTE: POWER SHOULD BE BROUGHTTOTHE UNITONLY AFTER ALLTHE MODULES
ARE CONNECTED TO THE MOTHERBOARD.
Remove the, transformer cover located at the left hand side of the box by unscrewing the nut at the
center of the housing (nearthe fuse). Bring 115 VAC to the appropriately labeled terminal strip. Once
the power is applied the display lights up and the buzzer should sound when the "push to test" button
is depressed. For problem identification see the section on trouble shooting. When each module
has been checked individually for proper operation. insert the screw at the top and bottom of the
module to the module in the box. (Fig.8)
D. COVER
When all the modules have been put in
the box, attach the window-frame to the
box by means of the two screws on
either: side of the frame.
The alarm is now ready for use.

TROUBLE SHOOTING
D. TROUBLE SHOOTING
Solutions are shown in order of the most probable problem.
PROBLEM SOLUTION
1. LIGHTS NOT ILLUMINATED (a) Check the fuse by removing the power module. The fuse is
directly behind the power module (Fig. 8). Replace the fuse if
defective.
(b) Check the building electrical breaker to ensure power is ON.
(c) Check the voltage at the terminal block above the transformer.
(Fig. 1) Ensure 120 VAC is being applied.
(d) Replace the power module.
2. NO AUDIBLE ALARM LIGHTS (a) Depress the "push to test" button. if the lights come on and
NOT ILLUMINATED there is no audible, replace the power module, if not try solu
tions for problem 1.
3. GAS READING INCORRECT (a) Ensure the gas going into the pigtails is being measured accu
rately.
(b) Ensure the sensor board is connected to the display board at
terminal J2. (Fig. 4)
(c) Ensure the display board is plugged into the motherboard. (Fig.
5)
(d) Replace the sensor board.
(e) Replace the display board.
4. ALARM CONDITION EXISTS (a) Ensure the system was properly ordered.
AND THEALARM UGHTSARE Normally HI pressure 60 psi.

Flat cables of each module are not connected to the mother
board.
Ensure flat cable on the power board is connected to the
mother board.
Ensure power lines from the transformer are connected to the
power board. (Fig. 3)
