2.3.1 24VDC Power Supply
The AX-PENN (/ST7) module must be powered from an ANSI/UL listed 24VDC fire alarm power supply/charger (i.e.
AX-PSU-6). Wire the 24VDC supply to the FEED 1 24V and 0V IN terminals (see figure 3). If utilizing the supply
voltage for other power requirements, wire the 24V and 0V OUT terminals to the other 24VDC device.
2.3.1.1 Power Supply Monitoring
If the AX-PENN (/ST7) is powered from an external listed power supply/charger, the power supply/charger must be
monitored for trouble conditions. To monitor the external power supply/charger, wire the AX-PENN (/ST7) terminals I/P
SW+ and SW- terminals to a “normally open” failsafe trouble contact of the power supply/charge and terminate with the
supplied 3.3K end of line resistor (see figure 4). If monitoring an intelligent internal power supply/charger (i.e. AX-PSU-
6) place the supplied 3.3K end of line resistor across the I/P SW+ and SW- terminals.
2.3.1.2 Intelligent Power Supply Monitoring
If the AX-PENN (/ST7) is powered internally by an Advanced AX-PSU-6 power supply charger, connect the supplied 4
pin connecter to the PL2 plug-in connector on the AX-PSU-6; connect the other end of the supplied 4 pin connector to
the PSU COM (PL3) plug-in connector on the AX-PENN (/ST7) [see figure 5]. In addition, within the PC-NeT
programming tool, under Panel Details, Trouble Notification; program the AX-PENN (/ST7) for intelligent power supply
monitoring by placing a check in the associated box (see figure 6).
