Connecting other equipment
Connecting auxiliary equipment
Connect auxiliary equipment to the 24VAUX output as shown in Figure 11 below.
The 24 VDC auxiliary output is supervised for short circuit and voltage output.

24 VDC
See Table 28 on page 85 for the maximum current and other output ratings.
Caution: Never use the auxiliary output to power expansion boards connected to
the same control panel as this might damage the control panel hardware.
Connecting alarm and fault relays
Connect alarm and fault equipment to the ALARM and FAULT relays.
Each potential-free relay output is activated in the corresponding alarm or fault
situation. The fault relay output is activated when there is no fault. This means
that there is a short circuit between the common (C) and normally open (NO)
terminals of the relay.
The maximum contact rating for each relay circuit is 2 A at 30 VDC.
