Tactical vehicles both up-armoured or not, can also take advantage of the installation of an AFSS system. A smaller control electronics (named CE slim) has been specifically designed for retrofit and small vehicles installation: it incorporates both the logical electronics and the control panel. A “night mode” is available to switch off all the leds in case of night watch operations. In the example shown a tactical vehicle is equipped with one CE slim system configured with four rugged temperature point detectors in the engine compartment and one extinguisher. In the crew two optical flame detectors and one explosion suppression are used to protect the personnel. Various configurations can be set via software in order to change the number of detectors and extinguishers to protect each compartment.

Temperature sensors may have a different temperature environment depending on how close to hot spots they are: to prevent overheat false alarms, the CE slim in the development or maintenance phase of the vehicle can be connected to a laptop computer to download temperature recording at the sensor location during each mission profile of the vehicles. With this database pre-warning and alarm thresholds can be set on the field for each location with the same safety margin.

Two pre-warning thresholds are available to warn the pilot of an overheat condition and one alarm threshold is also available; these three values can be set as increased temperature with respect to average mission temperature.
