A fire is automatically recognised by the FO 1362 and FT 1262 detectors. Remarkable feature of the FO 1362 visual fire detector is its high functional safety and quick smoke recognition. The differential detector FT 1262 measures the "temperature rise per unit of time" and is used where the use of smoke detectors is not possible, because of normal smoke development, e.g. by welding. The thermo maximum detector TH 4 provides an additional safety for monitoring of electrical wires to the individual smoke vent components.
