Test of reporting lines on a danger reporting assembly

摘要

The method involves measuring a standby-current of a detection line (U E) enclosed with end modules (D1, D2, R2). Reference value is compared with generation of error message during undercut of the value. A voltage in end of the detection line is limited by the modules to be equal to the value, where voltage is larger than a minimal detection operating voltage. A standby-current is adjusted using the modules to be equal to the value, which is larger than the sum of the standby-current of a detector (M) and smaller than an alarm current of an individual detector with minimal operating voltage. An independent claim is also included for a hazard detection system, comprising an end module.
