The LOOP +IN and Loop +OUT (loop positive in and out) connections are automatically joined together (short
circuit) by a spring arm between terminals 2 and 3 until the detector is installed. This allows for cable continuity
readings at the commissioning stage. Please remember that all high voltage testing must be carried out before the
installation of the electronics, otherwise the electronics will be damaged. Please also note that the SCRN terminal
should only be connected to the loop screen and NOT the building earth.
Once all testing has been carried out on the cabling and
continuity & insulation
has been proven, the Multipoint
ASD unit may be assembled.
