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
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 250psi for Pressure
sensors and 30” for vacuum sensors.
The new style sensors can read pressure up to:
Mid Pressure 99 Psi
Hi Pressure 249 Psi
Vacuum 30” Hg
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.
