Model SK-5208 Fire Control/Communicator Installation and Operation Manual
7-2 P/N 151204
Smk Pwr Trb Smoke power terminals 11, 14, 17, and 20 are
supervised. If the voltage between circuit ground
(terminals 9, 22, 26, 33) and loop power is less
than 20VDC this message will display.
This may occur when the maximum
current draw for the initiation circuit
is exceeded. See Section 3.11 for
initiation circuit current
requirements.
5235 Pwr Trb The power terminal for the 5235 is supervised and
a trouble indication will occur if the voltage
between circuit ground and terminal 32 drops
below 20 VDC.
This may occur if the maximum
current rating (1Amp) for this circuit
is exceeded.
Aux Pwr Trb The SBUS power terminal (27) is supervised and
will display this message when the voltage
between SBUS power and circuit ground drops
below 20 VDC.
This may occur if the maximum
current rating (1Amp) for this circuit
is exceeded.
AC Trb This message is displayed when the AC voltage
drops below 98 VAC.
Check the AC power connection.
This report will be sent to the central
station after the AC delay time has
expired. See Section 4.2.10 to
program AC delay time.
Battery Trb This message will be displayed when the battery
voltage drops below 20.4 VDC under load. The
control panel performs a load test every minute.
Check battery connection. Verify
that the control panel has AC power.
Ph Line # Trb This message is displayed when the phone line
voltage drops below 2 VDC or can not supply a
minimum of 4 mA of current. The # indicates
which phone line is in trouble.
Data Lost This event will be reported to the central station if
the reporting buffer fills. This may occur if more
that 24 events need to be reported. When the
report buffer is full and additional events are
added to the report buffer, the oldest event will be
overwritten and the data lost event will be added.
Com # Trb The SK-5208 must use alternating phone lines
(according to NFPA) when reporting auto tests
and manual tests. If the control panel can not
communicate using the selected phone line, the
Com # Trb message will be displayed. The #
indicates which line had the trouble.
The trouble condition will clear after
the control panel is successful in
communicating using the phone
line.
