Panasonic Electric Works Fire & Security Technology Europe AB Jungmansgatan 12, SE-211 19 Malmö, Sweden Tel: +46 (0)40 697 70 00 • Fax: +46 (0)40 697 70 99 • Fire alarm systems Multi detector 4350 • Low profile design / Unleaded soldering / Latest IC technology • One detector housing, two detector types and AI function General This low profile multi detector contains one photoelectric (optical) smoke detector and one heat detector within one housing. The latest IC technology is used to secure the highest reliability possible. In the smoke detection chamber is a highefficient optical system consisting of an LED and a photodiode with two lenses. Scattered light (i.e. reflection of infrared light) is used to detect smoke. The heat sensing element is a thermistor. Reduces false fire alarms The smoke enters the detection chamber through an insect filter and an optical labyrinth. This construction not only improves the smoke inflow but it also causes steam, fog, etc. to condense into moisture on its surfaces, to prevent false (nuisance) alarms. The detector maintains a constant sensitivity regardless of the contamination. It has also a self diagnosis of the internal devices. AI function • Combined heat and smoke sensing will guarantee reliable and accurate fire alarm detection. • Variable delay function, i.e. the delay time before fire alarm is activated, is influenced by temporary changes of the temperature and the smoke obscuration. • Learning function / condition means that the detector will adapt an alarm algorithm according to the smoke and/or temperature conditions where the detector is located, i.e. temperature changes and occurrence of smoke. There is a normal algorithm (default) and there are less and more sensitive learning conditions (algorithms) that will be adapted after a learning period. If the conditions changes, the normal will be adapted again. Environment friendly The detector has unleaded soldering. The latest IC technology reduces the number of semiconductors and other electronic components to a minimum. Compatibility The conventional multi detector 4350 is the best substitute for the ionization smoke detectors 2316 and 2317. Miscellaneous The detector is plugged in a conventional base (2324), connected to a conventional zone line input. The base has an LED that will light when the detector goes into alarm. In the base there are terminals to connect an external LED, e.g. 2218. Product applications The detector is intended for indoor use and in dry premises. It is excellent to detect all types of fires, also a methylated spirits fire. Used in the systems EBL500 / 512 / 128 / 1000 / 2000.
