SATEL Installer Manual 21

Information on powering detectors connected to expanders can be found in section

CONNECTING DEVICES TO EXPANDER BUS.

Figures 14, 15, 16 and 17 show various configurations of the detector connections. In the

presented examples, the detectors are powered from the AUX output. The signal from the

detector is supplied to the Z1 zone of the control panel. The Z2 zone in Figures 14, 15 and 16

has been programmed as type 9 (24H TAMPER). Separating the detector power supply ground

from the detector status signal ground eliminates the influence of the resistance of wires on

the detector status detection. Assuming that only one detector is connected to the cable and

the cable is not very long, the installation may be simplified by running one common single

wire for power supply ground and signal ground.

The NO, NC detectors in 2EOL configuration are connected in the same way, it is only

important to correctly indicate the type of detector connected the control panel (2EOL/NO or

2EOL/NC).
