APPLICATION

The HOCHIKI America AIE-EA Ionization smoke sensor has a responsive and highly stable operation that gives it an extremely wide range of uses. The AIE-EA can be used in areas where early warning of trouble from superheated or flaming combustibles is expected. The AIEEA is also constructed to be effectively used where outside RFI (Radio Frequency Interference) and other electrical interference is expected to be encountered.

OPERATION

A single radioactive source ionizes two chambers which causes a small DC current to flow between the electrodes in each chamber. Smoke can freely enter the outer chamber while the inner chamber is virtually sealed to smoke. Smoke entering the outer chamber causes a reduction in the DC current, the imbalance between the two chambers is proportional to the smoke density. The two chamber design is utilized to compensate for changes in atmospheric and environmental conditions. When the sensed input value exceeds a predetermined threshold, an interrupt is issued to the control panel indicating a fire alarm. The fire alarm control panel can adjust the sensor threshold to compensate for contamination. Up to 127 devices are permitted on each loop. A sensor address can be set by a hand held programming unit. The sensor mounts to an electronics free base and incorporates a locking mechanism for secure installation. The base provides mounting slots, terminals for field wiring and a third contact for a remote indicator/LED. The sensor incorporates dual LED's for easy viewing of sensor status.

ENGINEERING SPECIFICATIONS

The contractor shall furnish and install where indicated on the plans, dual-chamber, ionization smoke sensor HOCHIKI America AIE-EA. The combination sensor head and twist-lock base shall be UL listed compatible with a UL listed fire alarm control panel.
