Figure 6 - Coordinator Zone Connection Diagram 1
In cases where the coordinator is connected to the end of the zone line, the line end resistance gets
directly connected to the necessary terminals as shown in the following connection diagram. The
coordinator, in case of a fault occurrence in the wireless system, separates the
“Z
-
IN”
and
“Z
-
OUT”
ends and makes the line end resistance become an open circuit and thus provides the fire alarm panel
to cause an open circuit fault. In such case, since no other devices will remain on the rest of the line,
all devices on the other side of the line will keep on operating.

Siren Line Connection
Conventional sirens operate according to the voltage applied by the fire alarm panel to the siren line.
Conventional wireless coordinator, follows the siren line and decides whether the wireless siren will
set off or not. At the same time, just like in the zone line, it can check the siren line end resistance and
inform the fire alarm panel about any fault situation regarding the wireless sirens. There are two
