Connection for terminals '5' and '6'
If a point detector is removed from its detector base, all downstream detectors on
the stub remain active.
This function is only guaranteed if the following points are observed when installing
the detector base DB721D:
●
The cable coming from the control panel or the control panel's cable is
connected to terminal '5'.
●
The cable routed towards the EOL resistor is connected to terminal '6'.
Check that the cables are installed correctly by performing an appropriate function
test.
Diode unit for detector base DB721D
A missing, damaged or incorrectly installed diode unit can impair detection of a
point detector being removed from its detector base. Check that the diode unit is
functioning correctly by performing an appropriate function test.
