APPENDIX A: TROUBLESHOOTING
Trouble Action
No Power
Power On LED is Not On
Check Power Supply
Check for supply power at TB8 pins 2 and 3 on the bottom right hand
corner of PCB.
1) If power is not present at TB8 pins 2 and 3, check AC input voltage to
wall adapter, if used.
2) If power is not present at TB8 pins 2 and 3, check DC voltage at DC
supply source distribution panel.
3) If voltage (power) is present at TB8, please contact RLE Technologies.
Cable Fault on Zone(s)
Check for Proper Wiring to Terminal Blocks TB4, TB5, TB6 and TB7
Wiring order should be as follows from left to right: White, Black, Green
and Red.
1) If wiring order is correct, disconnect the End-of-Line terminator from
the end of the orange sense cable. Then connect the End-of-Line
terminator to the end of the leader cable (non-sensing). Push reset once
connected to reset control head.
2) If the cable fault condition goes away, there is a faulty or damaged
section of orange cable (sense).
3) If the fault condition does not clear, remove the respective zone
terminal block and remove the input wires from the leader cable.
Install a jumper wire between pins 1 and 2, and another jumper wire
between pins 3 and 4.
4) If condition still exists, please contact RLE Technologies for extra
support. If the condition clears, the leader cable is faulty (open
wire(s)).
Leak Detected on Zone(s)
Be sure there is No Water Present on or around the Zone in Alarm
1) If water is present, dry affected area and reset the controller. If the
condition does not clear follow the step below.
2) Remove the end-of-line terminator from the end of the orange sense
cable and install it onto the end of the leader cable. If the condition
clears, there is a water leak or damage to the sense cable. Start moving
the End-of-Line terminator to the end of each cable section until the
water-detected fault reoccurs. If the condition is still present once the
End-of-Line terminator has been placed on the end of the leader cable,
follow the step below.
3) Disconnect the proper terminal block from the zone in alarm. Place a
jumper wire between pins 1 and 2, and place a jumper wire between
pins 3 and 4. Plug the terminal block back into the proper socket and
push reset on the control head. If the condition is corrected, there is a
problem with the leader cable. If the water leak condition is still
present, contact RLE Technologies for support.
