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 v e r y reliable.
• Modular construction e a s e of maintenance.
• Plexiglass front covere a s y 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 b y the pressure display
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.

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.

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 AND SENSOR MODULES

AREA ALARM
The Amico Alert-1 Series of Master and Area Alarms are precision electronic monitoring and
alarm instruments that are factory calibrated and set according to the most current N.F.P.A. and
CSA standards.
The N.F.P.A. 1993 edition specifies that all pressure gas alarm points "shall indicate if the
pressure in the piping system increases or decreases 20% from the NORMAL OPERATING
pressure.

Calibration Procedure for the Pressure Display Module
Setup:
Connect the display PCB to a well calibrated Sensor module in a working frame and
power supply.
The calibration of the pressure module requires the following equipment:
- Source of known pressure with a reliable gauge or pressure measuring instrument.
Procedure:
1
Set the jumper selections SW1, SW2, SW3 and SW5 according to the pressure
range to be calibrated.
2
Set the calibrate/operate switch (SW4) to the calibrate position.
3
Apply power to the module.
4
Disconnect the pressure sensor module and short terminals #1 and #4 of connector
J2 on the display module. Adjust R22 for zero numerical indication.
5
Reconnect the pressure sensor module and apply a known, measured pressure
(preferable at least 90% full scale) to the pressure transducer.
6
Adjust R25 for the appropriate numerical indication for the range and units of
display settings of SW1, SW2, SW3 and SW5. Repeat steps 4,5 and 6 until
satisfactory.
7
Apply an input for 50% of scale. Adjust R42 to place the bargraph display at
center.
8
Confirm that the decimal select jumper SW3 will turn on either the middle or
right hand decimal points.
9
Confirm that alarms are generated and that the "HI ALARM" and "LOW
ALARM" LED's flash and the "NORMAL" LED extinguishes, by changing the
pressure out of the safe area (+/- 20%), or by readjusting R42 to artificially move
the LED bar display.
10
Put the calibrate/operate switch (SW4) to the operate position.
The Pressure Display Module is factory calibrated for set points at 40 PSI (LOW)/60 PSI
(HIGH). If you wish to change the settings, you would adjust "R42" to move the whole
range up or down. DO NOT adjust "R22" and "R25", they are factory set at "0" and full
scale. Do not adjust the potentiometers on the sensor modules, they are also factory set at
"0" and full scale. To obtain a larger or smaller range you must change "SW2" and then
adjust "R6" to obtain the proper range. You would then adjust "R42" to obtain the desired
values.
