  • Factory New
Brand: Siemens Part #: 153681 Categories: , Manufacturer Part #: ILI-1B


Compatible with the IXL, MXL and XL3 Control Panels, the ILI Series, ILI-1, ILI-1A, ILI-1B, ILI-1H, ILI-1AH, ILI-1BH, are plug-in, two-wire intelligent ionization smoke detectors offer the most advanced method of detection, programming, and communications with an alarm indicating LED. The ILI Series ionization detectors consist of self-compensating dual ionization chambers and highly stable solid state electronic circuitry, providing an extremely high degree of resistance to RFI, EMI and humidity. 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 and supervision algorithms. The ILI Series intelligent ionization detectors are compatible with SensorLINK FPI-32 or DPU field programmer/ tester. The FPI-32 is a compact, portable, menu-driven accessory which makes programming and testing detectors faster, easier and more reliable than other methods. The FPI-32 eliminates the need for cumbersome, unreliable mechanical programming methods and reduces installation and service costs by electronically programming addresses and functionally testing the detector’s performance before the detector is installed. UL and ULC Listed, and FM, CSFM, and NYMEA Approved.
