Symptom Problem Solution
AC Power
LED ON
System trouble LED
ON
Circuit trouble LED
ON
Notification appliance circuit trouble
1. Check TB2 for proper connections (TB3 for 4XB panels).
2. Remove all field wiring and install dummy ELR at
output circuit. Check for supervisory voltage across it
(Normal -2.3 V). If problem persists, replace circuit board.
3. Removed dummy ELR, reconnect field wiring and measure
voltage across output; (trouble -5V, short 0V).
4. Check for ELR at last device.
5. Check field wiring.
Any of the right
column yellow
LEDs flashing
Initiating zone open circuit trouble
1. Check TB4 for proper connections.
2. Remove field wiring for zone in trouble and install dummy
ELR (4.7K for 24V; 2.2K for 12V). If problem persists, replace
circuit board.
3. Check for ELR at last device.
4. Check field wiring.
Any of the right
column yellow
LEDs steady ON
Zone disable 1. Check installation manual.
Power trouble LED
ON
Battery trouble
Batt yellow LED
ON
Missing or
Disconnected
1. Check battery connections.
Low or damaged
battery
1. Remove batteries, check voltage across charger output (17 to
19V for 24V; 8-10V for 12V), otherwise replace circuit board.
2. Reconnect batteries, measure battery voltage at battery
terminals. If voltage is less than 85% of rated voltage, allow
them to charge for 48 hours.
3. If problem persists, replace batteries.
Ground fault trouble
Earth yellow LED ON
1. Remove field wiring from main panel and optional module(s)
(if installed). Install dummy ELR (4.7K for 24V; 2.2K for 12V).
2. Remove both battery leads.
3. If trouble clears, connect one circuit at the time to pin point
the problem.
4. If trouble doesn’t clear, replace circuit board.
Yellow LED on
4XTM ON
4XTM 1. Move Municipal Box disconnect switch SW1 up.
OPT1, OPT2 jumper cut
1. Install optional module(s) or replace jumper if module(s) is
not used.
Municipal Box open circuit
1. Install dummy load if Municipal Box option isn’t used.
2. Check Municipal Box wiring.
Any of the right column red LEDs ON Short on initiating circuit wiring
1. Remove field wiring and install ELR. If trouble clears, look
for faulty or incorrectly wired devices.
Disconnecting Municipal Box switch ON
4XTM does not create a trouble
Jumper for optional modules isn’t cut 1. Cut associated jumper OPT1 or OPT2.
4XZM: associated LED doesn’t activate
for alarm, trouble or supervisory
conditions
Optional module trouble
1. Make sure module is properly installed.
2. Move disable switch SW1 on 4XZM to the left.
RZA-4X piezo doesn’t sound for alarm,
trouble or supervisory conditions
4XLM
1. Make sure that 4XLM module is installed on J8.
2. Check field wiring.
Micro Fail yellow LED ON Microprocessor damaged 1. Replace circuit board.
All RZA-4X LEDs stay ON Power wasn’t removed prior to installation 1. Press system reset.
AC Power
LED OFF
System trouble LED ON
Loss of main power 1. Check incoming power (TB5). (TB1 for 4XB panels)
Damaged circuit breaker 1. Replace circuit board.
Micro Fail yellow LED ON Microprocessor damaged 1. Replace circuit board.
