Title: Ionization type smoke detector
Inventor: ARAKI TSUNEHIKO
IPC: G08B17/11
Filed: 1978-05-24
Abstract: PURPOSE:To minimize radioisotope and increase smoke sensitivity by periodically applying positive and negative alternating voltages between both electrodes installed in one ion chamber and detecting the ion current change occuring in smoke. CONSTITUTION:When positive and negative alternating voltages are applied by an AC power source 1, positive and negative alternating current flow through a load resistance 4. When the voltage generated in the load resistance 4 by said alternating currents is amplified in an amplifier circuit 5 and is then clampled to the negative side in a synchronous rectifier circuit 7, a constant voltage of negative is generated. When smoke enters the ion chamber, the ion current decreases, and in proportion to this, the negative voltage decreases. When the value thereof becomes lower than the value having beforehand been set by a threshold value discriminating switch circuit 8, the switch circuit operates to trigger an alarm device 8. Such constitution minimizes radioactivity of radio isotope 3 and enables smoke sensitivity to be enhanced.
