This chapter contains two flowcharts, one containing the Z-28’s power up
sequence and one that can be used to troubleshoot AC power problems.
Be aware of the following when using these flowcharts.
• The power up sequence occurs quickly. On a properly functioning
system, some phases of the power up sequence (for example, the span of
time during which the boot software revision is displayed) appear on the
Liquid Crystal Display (LCD) for only a few seconds. It may be necessary
to run the power up sequence several times, as you read the flow chart, to
properly interpret what is happening.
• You can skip these flowcharts if your system has powered up
correctly and is displaying a trouble message on the LCD. Refer to
Chapter 2 for descriptions of the Z-28’s trouble messages.

Note 1: When the system displays “1.02.xx”, this indicates the revision level of the boot software and does not
indicate the revision level of the panel’s BIN file. Refer to “Determining the BIN File Software Revision,”
in Appendix C of this manual for additional information.
Note 2: The SFIO board must be factory adjusted, tested, and loaded with the latest version of BIN file prior to
shipment. If a new SFIO board is received in the field and there is no BIN file loaded on it (i.e., a system
with a new SFIO enters a continuous link scan/code scan loop), this indicates that the board has not been
factory adjusted and tested. Order a new SFIO board, call Service Support to report the problem, and refer
to Appendix B of this manual for information on brownout potentiometer adjustment.
Note 3: The BIN file is available from Technical Support.

or
NACs 3 & 4 Class A
Check the following:
• Verify that a Class A adapter card is actually installed. This error
occurs if the NAC’s device type is Class A and the adapter card is
not installed.
• Power down the panel, remove the Class A card and reseat it in the
header on the NAC. Check to see that the pins of the Class A card
are properly seated in the header on the NAC card and power on
the panel. If the trouble does not clear, power down the panel
again and swap another Class A card in place of the suspect card.
If the problem still occurs, replace the SFIO board.
• Check the field wiring for opens and shorts.

Type Trouble Message Possible Causes / Troubleshooting
NAC
Card
Troubles
NAC 1 Signal Power
NAC 2 Signal Power
NAC 3 Signal Power
NAC 4 Signal Power
Indicates a power trouble on the NAC. Check the following:
• Check the load on the NAC in question while it is in the alarm state.
The load on each NAC must not exceed 2A. The SFIO board has
overcurrent protection for each NAC. An overloaded NAC trips this
protection and displays a NAC Signal Power Trouble for the circuit.
Unless the circuit is grossly overloaded, you should have several
seconds to measure the voltage before the protection trips. Measure
the current in either one of the following ways:
- Current Draw for a Single NAC. Use a DC ammeter, connected
in series with the load, to measure the load.
- Current Draw for all NACs. Measure the voltage across R150,
which is located above the LCD on the left-hand side of the SFIO.
Divide the measured voltage by .025. The result is the sum of all
NAC and auxiliary power loads.
• If the problem is with NAC 3 or 4, and they are powered by the Z-28’s
Expansion Power Supply (EPS), check the following:
- Verify that the red shunt has been removed from connector P13
on the SFIO board.
- Verify that the red (power) harness is connected to P1 on the
EPS and P13 on the SFIO board. Verify the white harness
(communication) is connected to P14 on the SFIO and P2 on the
EPS.
- Remove the harness and visually inspect each female pin on
both harness connectors. Make sure that none of the pins is
pushed back into the connector. Gently tug on each wire at the
back of the connector. If a wire pulls out from the connector,
re-insert it until the pin clicks back into place. Meter each wire for
continuity.
- Verify that no circuit draws more than 2A.

• The SFIO board is bad.
AC Power
Indicates AC line voltage is too low for proper system operation. Use a
meter to verify that the AC circuit is supplying power to the panel. This
circuit’s voltage must be 120 VAC +10% / -15%.
If the circuit supplying power to the panel has sufficient voltage, check
the adjustment of the AC Voltage Brownout Potentiometer. See
Appendix B of this document.

Expansion Power Supply
Indicates an Expansion Power Supply (EPS) problem. Try the
following:
• Verify that the AC circuit to which the power supply connects is
supplying 120 VAC (+ 10% / - 15%).
- If voltage is present, suspect the EPS transformer, the EPS
bridge rectifier, the connectors, or the harness running from the
EPS to the SFIO. Refer to Appendix B for information on
troubleshooting these components of the EPS.
- If no voltage is present, check the AC circuit feeding the panel.
• Verify that the black battery wire on the EPS connects to the – Batt
terminal on the Z-28. Even if you are not using battery backup for
the EPS, you must connect the black wire to the – Batt terminal.

Run the Earth Fault search diagnostic. If the results of the Earth Fault
search do not isolate the source of the fault, try the following:
• Disable each NAC one at a time, checking each time to see if the
fault clears.
• Disconnect the AUX power from the panel. Check to see if the fault
clears.
• Disconnect the N2 communications from the panel. Check to see if
the fault clears.
If the fault is intermittent, use the Earth Fault Latch, located in the
Function menu, to silence the fault until the intermittent problem can be
isolated and fixed. Note: After fixing the problem, you will need to
perform a system reset to clear the Earth Fault Latch.

Battery Low
Indicates the battery voltage is low (less than 22.8 V), battery standby
is running low, and action is required.
Note that this may or may not indicate a problem. Do the following:
• Note the time of the Battery Low event and determine if the battery
has charged since the event occurred. If the battery is charging,
allow it to charge for a full 48 hours and then check the voltage of
each battery separately.
• If this event occurs without an AC Power fail (check the panel’s
history log for AC power failure events), suspect either bad
batteries (i.e., won’t hold a charge) or a battery charger problem.
See the battery charger troubleshooting in the “Battery
Depleted/Disconnected” trouble.
Battery
Depleted/Disconnected
Indicates the battery has a voltage less than 19.5 V. Do the following:
• Check the voltage at the battery terminal block on the SFIO board.
The voltage should be 27.6 VDC (+/- 200 mV). If voltage is
present, but less than 27.6 VDC, use R256 to adjust the charger
voltage. See “Battery Charger Trouble” description later in this
section.
• Check the fuse and replace if necessary.
• Check the voltage of each battery separately from the other
battery. If one battery is good and the other is bad, replace both
batteries. (Note: Batteries are always replaced as a set.)
Power

Points
Battery Low Cutout
This trouble only occurs if the Depleted Battery system option is
enabled. Indicates the battery has reached a depleted state, and the
system will function in one of two ways:
• Shut the system down. This is the ULC-required operation for
Canada. Depleted Battery system option requires a special wiring
harness to function in this way.
• When an alarm occurs, the system does not energize the panel’s
NAC circuits. This functionality occurs when the Depleted Battery
option is enabled, but the special harness is not used.
