Bosch fme-420-lsn-ttl LSN improved test tool fire alarm system LSN improved test tool





Distinguish fault detection and location based on LSN and LSN improved fieldbus, professional installation inspection for handover, including basic function test of file peripheral (for sounder and beacon) 33000 HK: fme-420-lsn-ttl test tool to test whether the fieldbus (LSN and LSN improvement) and peripheral components connected to the bus are set correctly and work normally. The LSN and peripheral components in the loop, stub or T-tap, and faults in wiring or components are identified and indicated. LSN fieldbuses belonging to the following panels can be tested with test equipment: Europe CE fme-420-lsn-ttl

function

The test tool has two main functions. First, all components connected to the fieldbus are detected automatically and their properties are displayed. Secondly, resistance measurement detects the divergence of line resistance and contact resistance.

Note that resistance measurements are limited to the loop topology. Stumps cannot be measured.
