Smoke Detector DESCRIPTION:
The SIH-24 and AIB-10 smoke detectors are industrial type detectors connected to and operated from a central fire control unit.
These detectors are designed such that the radioactive material is not readily accessible to installers or users.
The SIH-24 and AIB-10 use the same ion chamber.
The only physical difference between the SIH-24 and the AIB-10 is in the overall size of the detectors, and that the SIH-24 has a small LED.
The SIH-24 is approximately 4" (10 cm) in diameter and 1.5" (3. 8 cm) in height.
The AIB-10 is approximately 3" (7.5 cm) in diameter and 1.75" (4.4 cm) in height.
The AI_ Series smoke detectors are also industrial type detectors that are connected to and operated from a central fire control unit.
The series includes the models AIE and AIC detectors.
The basic ion chamber design and construction for the two models within the series is essentially similar.
Cosmetic differences, including different outer cases, account for slight dimensional differences.
The following is a comparison of the ion chamber construction:
Description AIE AIC Isotope / Activity Am-214, 1.0 pCi Am-241, 0.98 pCi Source Holder Diameter 0.44" (11.2 mm) 0.44" (11.2 mm)
Inner Electrode Length 0.71" (18 mm) 0.35" (9 mm)
Intermediate Electrode 1.65" (4 2 mm) 1.46" (37 mm)
Diameter Outer Electrode 1.97" (50 mm) 1.73" (44 mm)
Diameter Hochiki distributes these detectors under different trade names, and includes the different product codes on the point of sale labeling.
