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.
