CAUTION: The microprocessor circuitry on the ALERT-2 alarm con-
tains 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
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.
B: REMOTE (outside the back box)
i. Connect a tee (supplied by others) to the pipeline with a 1/4” NPT female
connection that will accept the DISS Demand Check Valve.
ii. Locate the gas-specific sensor module to be installed.
iii. Thread the DISS Demand Check Valve into the correct gas pipeline.
iv. The sensor module contains a gas-specific DISS fitting. Push the sensor module
hex-nut and nipple adapter into the demand check-valve. With a wrench,
tighten the nut so that it makes a good seal.
v. Marrette in a junction box (supplied by others) the #22 gauge stranded,
shielded twisted pair sensor cable to the installation cable (supplied by others).
vi. In the presence of any electrical, magnetic, radio frequencies, wireless or other
interference, cable installation (supplied by others) running from the junction
box (supplied by others) to the alarm MUST be placed in a metallic conduit.
STEP 5: FRAME ASSEMBLY
i. Remove the frame assembly from its protective box.
ii. Remove the corner screws from the front frame section (4 screws).
iii. Attach the LCD screen to the back box assembly by using flat head screws
(provided with frame in a plastic bag) to the hinge located on the back box.
iv. Attach the frame wire with 2 dome head screws (provided with frame in a
plastic bag). This will allow the frame assembly and back box to be fastened
securely together.
CAUTION:
1. The microprocessor circuitry on the ALERT-4 alarm contains sophisticated integrated semiconductors.
DO NOT TOUCH
any of the components on the board. Static discharge can cause the modules to
malfunction or become damaged.
2. Keep the shield drain wires as short as possible and taped to prevent from grounding, so they can not
touch the front panel circuit board when front panel is closed.
