Aux power

EN54-13 (BOSEC certificate TCC 2 - 977)
The fire panel allows you to use 4-wire (4W) elements on the
last zone. These must be supplied with power by the auxiliary
power supply or an external power source. Both the zone and
the auxiliary power must be terminated by a terminal element.
For EN 54-13 (BOSEC certificate TCC 2 - 977) compliant
connection of 4‑wire elements, the AUX and zone lines must be
routed in separate cables.
You can either use a 3.9 kΩ ±1% resistor or EOL modules for
EN 54-13 (BOSEC certificate TCC 2 - 977) compliant
termination.
Program the reset behavior of the auxiliary power as described
in Aux Power, page 37.
Notice!
Note that the maximum line resistance for the auxiliary power is
22.5 Ohm.
