6 Amico Corporation
Description of Modules
The Alert-4 Area 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” button. The function of the “MUTE” button is to silence an alarm that
has occurred. By holding the “MUTE” button for 20 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 applications requiring a
remote audible alarm, master alarm or a Building Management System.

SHIPMENT DETAILS
When you receive an Alert-4 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.
