Description of the Alarm
SHIPMENT DETAILS
When you receive an ALERT-2 series alarm from Amico Corporation, the package will consist of two main sections; the
Alarm Back Box and the Frame/Module Assembly. The Frame/Module assembly will be pre-congured, with the appro-
priate display modules, based upon the customer’s specications.
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 ter-
minal blocks (115 VAC, or 220 VAC). 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 all the modules that are pre-assembled to the customers speci-
cation. 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.
The ALERT-2 alarm is divided into 4 or 7 main modules:
COMMON TO ALL ALARMS
1. 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 LED’s. 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 annunciator module. The System Power Supply can be easily removed
and reinstalled by unscrewing it from the back box.
