SYMPTOM
POSSIBLE CAUSE
POSSIBLE SOLUTION
2. Transmitter Board
(KCi #66950)
Isolate boards by moving battery from interface
jack direct to transmitter jack. Replace board.
Will not Transmit
1. Fuse
Replace
2. Transmitter Board
Replace board
3. Battery
When battery voltage is less than 11.8 volts
replace battery
Weak Transmit (Misses
Occasionally)
1. Antenna SWR Check
Check Antenna installation
2. Antenna Location
Try a different antenna location
3. Coax Connectors
Gently twist BNC connector. Look for rotation
or other indications of improperly installed
connectors.
TRANSMITTER shows up on
the Missing Box report.
Check fuse
Verify 25.000000±0.000050MHz at TP1 after
pressing Program button. (Adjust R20 at
Factory Only)
Check Console for “LB” normal battery shut-
down
Check battery voltage under load, it should be
above 11.8 VDC
If transmitter “beeps” analyze signal by listening
to speaker & watching Signal Meter on Console
Check test time on Console printer tape; avoid
other transmitter auto test times
Check antenna connector and perform SWR and
Power test. SWR should be < 1.5:1.
Power out should be 0.5-1.0 Watt
Try a different address code
Substitute electronics from another “working”
transmitter
TRANSMITTER sends an
unexpected zone message every
time another message, such as
test, is sent. The same zone
message is sent immediately after
the Reset Button is pressed.
First, with the ribbon cable removed, measure
the voltage on all pins of the bottom row of
J5. Each pin should measure approximately 3.0
VDC; no pin should be less than 2.4 VDC. If
any of them is lower, replace the transmitter
board.
Next check for ribbon cable short
circuit. Unplug the ribbon cable from J1 on the
Interface module and press the Reset Button on
the Transmitter module to see if the zone
transmits. If so, replace the ribbon cable.
16.1 Monitoring Hardware Errors
Three hardware errors are monitored by the microprocessor and when detected will prevent the
transmitter from operating. When any of these hardware errors is detected the transmitter shuts
down all circuitry that it can and sends a continuous stream of characters out of its Bluetooth
connection. It does so infinitely until the problem is corrected by human intervention.
Connecting the terminal program to the Bluetooth port will show text that indicates the specific
problem that was detected.
