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 Photoelectric smoke detector 4352 • Low profile design • Latest IC technology / highest reliability • Unleaded soldering General The photoelectric (optical) smoke detector has a low profile design. In the detection chamber is a high-efficient 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 latest IC technology is used to secure the highest reliability possible. 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 has a counter. A reading over the alarm level is +1 on the counter and a reading below the alarm level is -2. The counter starts at 0 and can not be negative. When the counter shows "9" the detector goes into alarm, i.e. a minimum of nine consecutive readings over the alarm level are required before the detector goes into alarm. (One reading per sec.) 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 photoelectric smoke detector 4352 is a substitute for the photoelectric smoke detector 2321. 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. There are also terminals in the base 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 large, bright smoke particles as from a smouldering fire. Used in the systems EBL500 / 512 / 128 / 1000 / 2000.
