The SIJ-24 can be used in all areas where Ionization Smoke Detectors are required. The responsive yet highly stabile operation allows the SIJ-24 to fit in a wide range of uses. The SIJ-24 can be used in areas where early warning of superheated or flaming combustibles is expected.

NS-4 Series, NS-6 Series, HSC-4R or HSC-R Style bases may be used with the SIJ-24. Current compatible devices are the SLR-24V Photoelectric detector, the SLR-24H photoelectric detector with heat sensor and the DCD-135°/190° heat detectors.

All NS conventional devices are mechanically compatible with Hochiki America HSB, HSC and YBA type bases which may have been used in previous installations. Please check individual panel listings for compatible bases.

The SIJ-24 ionization smoke detector utilizes two bicolored LEDs for status indication purposes. In a normal standby condition the LEDs flash green approximately once each second. When the detector senses smoke and goes into alarm the status LEDs will latch on red.

A single radioactive source of Americium-241 ionizes two chambers within the detector, a reference chamber, and the smoke sensing chamber. The air is ionized by this source and a small DC current flows between the electrodes of each chamber. Smoke can freely enter the sensing chamber while the inner chamber is virtually sealed to smoke. Smoke entering the sensing chamber causes a reduction in the DC current flow, the voltage
imbalance between the two chambers is proportional to the smoke density. When the voltage differences become great enough it causes the detector to go into alarm. The two chamber design is utilized to compensate for changes in atmospheric and environmental conditions.
