Appendix A: Troubleshooting

Do not use this section as an acceptance testing
procedure. This information is provided as a general
guide to help you determine, recognize, and resolve a
system problem during installation, maintenance, and
normal standby.
A.1

On-Board LEDs

The FPT-DACT has four on-board LEDs that indicate
various system conditions.
Line 1 LED: This LED blinks if a report is being sent
out on Line 1. If a line fault condition occurs on Line 1,
this LED lights steadily in conjunction with the Sys
Trouble LED. If the Line 1 LED lights steadily:
1. Use a voltmeter to measure the voltage present
across each telephone line (Tip to Ring), while the
telephone line is idle.
The voltage present while an incoming call is
present can be more than 100 VAC.
The standby Telco battery voltage should be
between 30 VDC and 50 VDC. The FPT-DACT
accepts any voltage over 6 VDC.
The voltage polarity does not matter.
2. Check for other devices that use the telephone line
such as fax machines, credit card verifiers, or PBX
systems.
NFPA 72 requires a dedicated telephone line for
fire reporting. If the devices sharing the
telephone line cannot be removed, verify they are
wired so the FPT-DACT's line seizure relay
disconnects them when needed. Measure the line
voltage while these devices are in use, verifying it
remains above 6 V.
3. Check for intermittent faults on the telephone line.
Make a test call to verify the line is free of
distortion and noise. Temporarily swap Lines 1
and 2 on the FPT-DACT to check if the problem
indication moves to the FPT-DACT's other
telephone line channel. If the problem indication
moves, the telephone line is causing the problem
rather than the line monitor.
Verify the fault message is PHONE FAULT and
not COMM FAULT. Set report steering for all
events to Phone 1 Only if only one telephone
number is available for reporting.
COMM FAULT can also happen if one of the
telephone lines has Telco battery voltage, but
does not complete a call. Make test calls to the
receiver(s) on both telephone lines, listening for
the receiver ACK tone.

4. Verify two telephone lines are available.
NFPA 72 requires the Auto Test Report be sent
on a different telephone line each time it is sent. If
only one telephone line is connected to the FPT-
DACT, a COMM FAULT is generated on every
other test call.
Line 2 LED: This LED blinks if a report is being sent
on Line 2. If a line fault condition occurs on Line 2, this
LED lights steadily in conjunction with the System
Trouble LED. If the Line 2 LED lights steadily, refer to
the preceding steps for Line 1 LED.
Heartbeat LED: This LED illuminates and flashes if the
FPT-DACT is functioning properly. When this LED
does not light:
Check the FPT-DACT's main power. Refer to Table 1
on page 5.
Verify there are no wire faults in the power
connections.
Refer to Section 1.2.1 Power on page 5 for additional
power requirements.
Sys Trouble LED: This LED is off when the FPT-
DACT operates properly. It lights steadily for any FPT-
DACT system trouble. It also operates in conjunction
with the FPT-DACT's on-board trouble relay. The
number of times the Sys Trouble LED blinks determines
the trouble condition indicated (Table 9).
