efficiently. If you cannot resolve the fault with the assistance of this guide, call Technical Support at 800.648.7424.
Table 7. Troubleshooting Guide
Trouble indicators
Possible cause
Corrective action
End-of-line resistor value incorrect or missing
Meter circuit to verify proper resistance
Loss of power to power supervision relay
Meter voltage on circuit
Polarity reversal relay wired incorrectly
Check circuit diagram to confirm wiring
Loose connection or broken wire
Check for opens in circuit
Zone 1-5 trouble LED
Disconnect/Walktest switch not in normal position
Put Disconnect/Walktest switch in normal position
System trouble LED
Faulty waterflow switch
Repair or replace waterflow switch
Trouble sounder slow
Initiating device missing from circuit
Check for any devices that may have been removed from the
intermittent
initiating circuit
“Class A” wires crossed in circuit
Make sure polarity is observed completely through circuit
“Class B” wires connected to wrong terminals
Make sure wires are connected to “Class B” terminals
Incompatible two wire detector
Check UL compatibility listing to verify the detector is listed for
use with the panel
Overcurrent or lightning damage
Check for burn marks or other signs of overcurrent damage.
Return to factory for service. Replace board if traces are damaged.
Supervisory trouble LED
Zone 2 supervisory device tripped
Check initiating device on zone 2
Rapid trouble beep
Zone 2 alarm LED
Remote annunciator zone 2
System trouble LED
Open in zone 2 circuit
Check zone 2 for broken wires or opens in circuit
Zone 2 trouble LED
Rapid trouble beep
Disconnect/Walktest switch not in normal position
Put Disconnect/Walktest switch in normal position
Loss of AC (line voltage)
If line voltage is too low, upgrade or move to new circuit
Low/No AC power
Low AC power
If secondary shows less than 22 VAC replace transformer
System trouble LED
Less than 94 VAC at transformer primary-no load
Trouble sounder slow
Less than 102 VAC with maximum load
intermittent
Less than 22 VAC at transformer secondary-no load
Damaged transformer or loose connection
Check for loose or broken connections
Battery low
Replace batteries
Low/No battery LED
Less than 24 VDC
System trouble LED
Battery missing or less than 20 VDC
Replace batteries
Trouble sounder slow
Blown fuse
If fuse is blown, determine why fuse was blown, correct problem,
intermittent
and replace fuse
Open in battery harness
If there is an open or break in the battery harness, replace it
Ground fault LED
Ground on any circuit, other than alarm or trouble
Remove one wire at a time until ground fault LED and system
System trouble LED
contacts
trouble LED goes out. Repair circuit causing fault condition.
Trouble sounder slow
Ground in transformer
Remove AC input from board, if ground fault LED goes out,
intermittent
there is a ground in the transformer-replace transformer
End-of-line reistor value incorrect or missing
Meter circuit to verify proper resistance
Polarity reversed in circuit
Check circuit diagram to confirm wiring and polaity
Loose connection or broken wire
Check for opens in circuit
Indicating 1-2 trouble LED
Indicating device missing from circuit
Check for any devices that may have been removed from the
System trouble LED
indicating circuit
Style “Z” wires crossed in circuit
Make sure polarity is observed completely through circuit
Style “Y” wire connected to wrong terminals
Make sure wires are connected to style “Y” terminals
Overcurrent or lightning damage
Check for burn marks or other signs of overcurrent damage.
Return to factory for service. Replace board if traces are damaged.
System trouble LED
Bad ZEM connection
Check connector pins where ZEM connects to the BMB
Trouble sounder slow
ZEM malfunction
Check for signs of damage to the BMB or ZEM
intermittent
BMB malfunction
Return to factory for service or replace boards.
(with no other indicators)
