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.
