LSNi mode

Most of the classic features like topology characteristics and initialization order are
transferable to the Neo-Classic (or LSNi) mode. The address assignment command, the
address range and the cable range are different.
The address for the detector is not set by selecting the LSN address switch, but is
automatically assigned an address on the bus by the supporting control panel. The address
range is extended up to 254. Additionally the cable length can be increased up to 3000 m
(9842 ft). Numerous range tests confirm the law of Ohm as main restriction of the bus range.
Therefore, the cable length is dependent on the bus current and the number of installed
network elements.

Detection range

8 M 25 FT
The detector is designed to work in two different range modes. With the full range (or long
range) mode, both the upper and lower PIR elements operate to provide the rated coverage.
When the detector is set to short-range mode, the upper PIR element is disabled and the
device ignores the microwave Doppler radar signal changes caused by movement in the area
not covered by the PIR.
Both long range and short range modes are configured using remote programming software.
Refer to your remote programming software for detection range information.
Configuration
Detection range is configured using remote programming software (RPS). The detection range
options show Level 1 through Level 8:
