1 Introduction / Overview
1.1 Product Description
This manual covers the installation and operation of an Axis AX-PENN and AX-PENN/ST7 Peripheral Expansion
Network Node module for use on Advanced Ad-NeT-PluS networks. The AX-PENN is a Class B network interface
module, while the AX-PENN/ST7 is a Class X (A/Style 7) network interface module.
AX-PENN (/ST7) peripheral expansion network node modules provide an on-board Axis AX peripheral bus (PBUS)
allowing for the connection of any Advanced peripheral bus module remotely from the Axis AX fire alarm control panel
(i.e.: switch LED modules, audio amplifier modules, relays, etc.).
Each AX-PENN or AX-PENN/ST7 peripheral expansion network node module can support an optional AX-DSP
graphical keyboard display for localized network monitoring and control.
This equipment is constructed with static sensitive components. Observe anti-static precautions at all
times when handling printed circuit boards. Wear an anti-static ground strap connected to panel
enclosure earth ground.
CAUTION: Before installing or removing any printed circuit boards remove all sources of power (AC and
battery).

2 Installation
2.1 Mounting
The AX-PENN (/ST7) is designed for mounting within any Advanced enclosure. The module mounts wherever an
Advanced peripheral bus module can be mounted. In addition, the module can be mounted to a single aperture plate
for single aperture opening installation (see figure 1 mounting locations).
To ensure EMC immunity to fast transient and surges the AX-PENN (/ST7) must be connected to an earth ground.
Each installation screw of the AX-PENN (/ST7) module provides a ground connection to its associated mounting plate
for eventual earth ground connection via the mounting plate/enclosure.
Failure to tighten screws will defeat the protection circuitry designed to protect the card from damage due to
lightning and static electricity.

2.3 Wiring
The AX-PENN (/ST7) peripheral expansion network node module is designed to be easy to install and wire. Pluggable
terminal blocks are provided for all wiring which can accommodate up to 14 AWG wire. Confirm wiring sizes are
adequate to deliver the required load current and maintain compatibility with the device voltages.
Note: Disconnect all sources of power (AC and battery) before installing components or servicing the module.
All wiring must comply with local, state and authority having jurisdiction requirements, in addition to Article
760 of the National Electrical Code (NEC).

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).

4 AxisAX Wiring Guide
Unless otherwise noted, all circuits permitted to be in same conduit. Check local codes for additional restrictions. Twisted shielded
cable provides a degree of protection and immunity to electrical noise interference (RFI/EMI) compared to twisted pair or untwisted
wire. If shielded cable is used, connect the shield to the panel enclosure (out and return) and to the dedicated shield terminations in
the bases only.
Note: If shielded cable is utilized, the shield connection must be a continuous circuit around the loop and must not be in
contact with any other earth/ground point (including electrical back boxes).
If running NAC and/or 24 VDC circuits in the same conduit as other signals, you can reduce problems by exclusively using electronic
sounders instead of electronically noisy notification appliances (such as electromechanical bells or horns).

If multiple loops are inside the same conduit it is acceptable to use
twisted unshielded wire as SLCs will not interfere with one another. It is
acceptable to run other signals inside the same conduit however, it’s
recommended that the other wires are either twisted or twisted shielded.
The AxisAX panels contain loop power technology. The SLC circuits are
capable of driving high current loads in alarm, which affects the load
characteristics including V/I drops along the wire length. Therefore, it is
important to utilize Advanced loop calculator in determining wire gauge
and length.

Note that network node to node communications are optically isolated
and each node has an independent ground fault detection circuit. To
insure prevention of earth “ground loops”, the shield must be terminated
at one node and not both. This is accomplished internally at each node
via dedicated shield terminals.
Each network node module has isolated outgoing and incoming network
wiring terminals. Connect from the “OUT” terminal on the first node to
the “IN” terminal on the next node (A, B and Shield).

Note #1: SLC (Signaling Line Circuit)

Note #2: Notification Appliance Circuit
The voltage drop on notification appliance circuit should be calculated to ensure that the minimum voltage at the end of the circuit
exceeds the minimum required by each notification appliances at the minimum alarm circuit output voltage.
The voltage at the end of the circuit is given by:
Minimum Alarm Voltage = VOUT(MIN) – (IALARM x RCABLE)
Minimum Output Voltage (VOUT(MIN)) is VBAT(MIN) – 0.5V = 20.5V
Alarm Current (IALARM) is the sum of the loads presented by the notification appliances in alarm
Cable Resistance (RCABLE) is the sum of the cable resistance in both wires x cable length.

Note #3: Telephone Riser
Maximum Riser Circuit Cable Resistance = Max Riser Volt Drop / Total Firefighter Jack/Phone Current.
Max Riser Volt Drop = 5V
Total Firefighter Jack/Phone Current (A) = (number of phones x 0.0063) + 0.08
