2. ANNUNCIATOR MODULE

The Annunciator Module contains the buzzer, a “Power On” LED, the “TEST” and the

“ALARM MUTE” buttons. The function of the “TEST” button is to verify that the buzzer and all

the LED’s are in working condition. An alarm will be heard when this button is pushed and

all the LED’s will light up. When the button is released, the alarm will silence. The “ALARM MUTE”

button is used to silence an alarm that has occurred. 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 (see Appendix B), for connection to

another Amico Alarm or a Building Management System.

3. BLANK MODULE

The Blank Module is used as a filler board for future provisions of the alarm.

DESCRIPTION OF MODULES

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.

alarm.

AREA ALARM

4. AREA DISPLAY MODULE

The Area Display Module provides a digital display of the actual pressure/vacuum of a

gas being monitored. In addition a gas trend indicator bar with HIGH and LOW alarms

are displayed. The trend bar has three coloured LED’s: Green for Normal condition, YELLOW

for Caution condition, and RED for high and low Alarm conditions.

Each display module contains a gas specific colour coded label (USA or ISO colours are

available). A space is also provided, at the base of the module, to identify the location that

the display module monitors. The display module is field adjustable for pressure/vacuum

settings, repeat alarm, and units of measure. Whenever the module is in calibration mode,

the bargraph is flashing, indicating the calibration mode. Dry contacts for high and low

alarms are available for remote monitoring of each module.

5. 2 IN 1 DISPLAY MODULE

The 2 in 1 Display Module provides a digital display of the actual pressure/vacuum of the

gas being monitored. In addition, a gas trend indicator bar with High and Low alarms are

displayed. This module has two coloured LEDs - Green for Normal conditions and Red for

High and Low alarm conditions. It is field adjustable for pressure/vacuum settings, repeat

alarms, and units of measure. Dry contacts for high and low alarms are available for remote

monitoring of each module.

Each module will continuously monitor up to 5 signals from source equipment or pressure

switches. If any of the signals being monitored go into an alarm condition, a Red LED will

illuminate and the audible alarm will sound.

PLEASE NOTE: Contacts located on back of module are Dry Contacts only.

DO NOT apply any voltage.

AREA DISPLAY MODULE

The Area Display Module provides a digital display of the actual
pressure/vacuum of a gas being monitored. In addition a gas trend
indicator bar with HIGH and LOW alarms are displayed. The trend
bar has three coloured LED’s: GREEN for Normal condition, YEL-
LOW for Caution condition, and RED for high and low Alarm
conditions.

Each display module contains a gas specific colour coded label
(USA or ISO colours are available). A space is also provided, at the
base of the module, to identify the location that the display module
monitors. The display module is field adjustable for pressure/vacuum
settings, repeat alarm, and units of measure. Whenever the module
is in calibration mode, the bargraph is flashing, indicating the calibra-
tion mode. Dry contacts for high and low alarms are available for
remote monitoring of each module.

6.

SENSOR MODULE

The Sensor Module contains the transducer which converts the
pressure/vacuum pressure source into a digital signal that is dis-
played on the display module. The sensor module is housed in a
black ABS plastic fire rated enclosure to reduce the risk of tamper-
ing. Each sensor is clearly labelled and colour coded for the gas or
vacuum being monitored. The sensor module contains a gas spe-
cific DISS fitting to ensure correct connection of the proper sensor to
the respective gas. Each sensor has been factory calibrated for the
specific gas shown on the sensor housing. If it is not connected to
the appropriate gas display module, an error message (E02) will be
displayed.
