The complete modular leak
detection solution for
alternative fuel vehicles

Enclosure with window.
Four sensors are connected by cable
for installation in the vehicle.

A FuelGuard system consists of up to eight
leak detection modules (4 shown here) each
connected to a sensor located in a remote part of the vehicle.
Each sensor constantly watches for gas. When a sensor
detects gas, it sends a signal to the leak detection module which compares the level of
gas found to user-set limits. It has its own digital readout. The leak detection module
sends its alarms to the common alarm module.
Depending how the alarm module is wired the signal may be passed to the annunciator panel.
The alarm module has relay outputs for each alarm level which can be interconnected to
other vehicle systems (fire suppression or ignition interlock).
