Troubleshooting
February 2011 6-8 P/N 06-237041-001
L#: Addr 9V DC FAULT On Device
Type
A failure of the internally generated
9-Volt power supply for the SmartOne
smoke or heat detector at address
L#: Addr.
• Check SLC wiring. Refer to
Figure 2-24 and Figure 2-25. Ensure
that wiring resistance and
capacitance limitations have not been
exceeded.
• Visually inspect the detector to
ensure that its red LED is flashing.
Use Handheld Programmer to test the
device if the LED is not flashing.
Replace the detector if it fails the
Handheld-Programmer test.
• List the automatic initiating device's
9-Volt level. Refer to the list menu in
Figure 3-15. Replace the device if the
9-Volt level varies by + / - 1.0 (nom.)
Vdc volts.
• Conduct an initiating device test on
the automatic detector. See
Section 3-3.4
• Activate and confirm a proper alarm
response from the detector.
• Replace the device if any of the above
tests are unsuccessful.
L#: Addr ABORT TROUBLE On
Monitor Module
The abort switch being monitored by
the AI at address L#: Addr is activated
and the system is not in alarm
• Check abort switch for mechanical
failure
L#: Addr ALARM TEST FAIL Device
Type
An initiating device (i.e., automatic
detector or monitor module) at address
L#: Addr failed a device test. The
initiating device was unable to send an
acceptable alarm-test signal when
requested by the control unit.
• Globally isolate all outputs. See the
Global Isolate menu in Figure 3-12.
• Disconnect device from SLC and
visually inspect for damage. Clean if
automatic detector.
• Use Handheld Programmer to test the
device. Reconnect device to SLC.
• Conduct an initiating device test on
the initiating device. Repeat this
procedure at least 3 times. Refer to
the Test SLC menu in Figure 3-31.
Check SLC wiring if test results are
inconsistent. Refer to Section 2-8.5.
Ensure that wiring-resistance and -
capacitance limitations have not been
exceeded.
• Activate and confirm a proper alarm
response from the initiating device
• Replace device if any of above tests is
unsuccessful.
• Globally de-isolate all outputs. See
Figure 3-12.
