Amico Corporation

CAUTION

: The microprocessor circuitry on the ALERT-2 alarm contains sophisticated integrated semiconductors. 

If it becomes necessary to remove a module, PLEASE hold the boards by the edges. 

DO NOT TOUCH

 any of the 

components on the board. Static discharge can cause the modules to malfunction, or become damaged.

SENSOR

A. LOCAL (Inside the Back Box)

1.  Locate the gas specific sensor module to be installed.

2.  In the back box, there are colour coded gas labels located under the DISS Demand 

check valves. Each label identifies where each sensor module is to be placed.

3.  The sensor module contains a gas specific DISS fitting. Push the sensor module hex-

nut and nipple adapter up into the demand check-valve. With a wrench, tighten the 

nut so that it makes a good seal.

NOTE

: Pressure on sensors are not to exceed 

250 psi

 for Pressure sensors and 

30"

 for 

vacuum sensors. A failed or damaged filter may allow moisture or water in and damage 

the transducers.

The new style sensors can read pressure up to:

•  Mid Pressure 99 Psi

•  Hi Pressure 249 Psi

•  Vacuum 30" Hg

B. REMOTE (Outside the Back Box)

1.  Connect a Tee (supplied by others) to the pipeline with a 1/4" NPT female 

connection that will accept the DISS Demand check-valve.

2.  Locate the gas specific sensor module to be installed.

3.  Thread the DISS Demand check-valve into the correct gas pipe line.

4.  The sensor module contains a gas specific DISS fitting. Push the sensor module hex-

nut and nipple adapter up into the demand check-valve. With a wrench, tighten the 

nut so that it makes a good seal.

SENSOR

LOCAL (In the Back Box)

1.

Locate the gas specific

sensor module to be in-

stalled.

2.

In the back box, there are

colour coded gas labels

located under the DISS

Demand check valves. Each

label identifies where each

sensor module is to be

placed.

3.

The sensor module contains

a gas specific DISS fitting.

Push the sensor module

hex-nut and nipple adapter

up into the demand check-

valve. With a wrench, tighten the nut so that it makes a good seal.

NOTE: Pressure on sensors are not to exceed 

250psi

   for Pressure sensors and 

30”

 for Vacuum sensors

REMOTE (Outside the Back Box)

1.

Connect a Tee (supplied

by others) to the pipeline

with a 1/4" NPT female

connection that will accept

the DISS Demand check-

valve.

2.

Locate the gas specific

sensor module to be

installed.

3.

Thread the DISS Demand

check-valve into the

correct gas pipe line.

4.

The sensor module contains a gas specific DISS fitting. Push the

sensor module hex-nut and nipple adapter up into the demand

check-valve. With a wrench, tighten the nut so that it makes a

good seal.
