Siemens ILI-1A Ion Smoke Detector P/N:500-093023

Siemens Building Technologies, Fire Safety Division Siemens ILI-1A intelligent ionization smoke detectors offer the fire and life safety industry the most advanced method of detection, programming and communications available today. Additionally, the ILI Series detectors provide an extremely high degree of resistance to RFI, EMI and humidity. Besides, the ILI Series ionization detector utilizes a state-of-the-art Motorola microprocessor with “onboard” EEPROM. The microprocessor provides the power to operate the detector’s sophisticated detection, error checking as well as supervision algorithms.

The Siemens ILI-1A is plug-in, two-wire ionization detectors, compatible with Fire Safety IXL, MXL and XL3 control panels. Also, the ILI Series ionization detectors consist of self-compensating dual ionization chambers and highly stable solid state electronic circuitry. The ILI ionization detectors are applicable to the maximum 30 foot center spacing (900 sq. ft.) as referred to in the National Fire Protection Association Standard 72. This, however, is based on ideal conditions, namely, smooth ceiling, no air movement and no physical obstructions between the fire source and the detector. This spacing should be used as a guide or a starting point in detector installation layout.

Do not mount detectors in areas close to ventilation or air conditioning outlets. Exposed joists or beamed ceilings may also affect safe spacing limitations for detectors. It is mandatory that engineering judgment be applied regarding detector locations and spacing.

The ILI Series ionization detectors are also compatible with Fire Safety IXL, MXL and XL3 control panels.
