How to troubleshoot AC Power LED off on System Sensor Control Panel?
If the AC Power LED is off, it could be due to a loss of main power. Check the incoming power at TB5 (or TB1 for 4XB panels). Alternatively, a damaged circuit breaker could be the cause; in this case, replace the circuit board.
What to do if the Power trouble LED is on for System Sensor PDRP-1001 Control Panel?
If the Power trouble LED is on, it could be due to missing or disconnected battery connections, so check them. Alternatively, the battery might be low or damaged. To resolve this: 1. Remove the batteries and check the voltage across the charger output (17 to 19V for 24V systems; 8-10V for 12V systems). If the voltage is incorrect, replace the circuit board. 2. Reconnect the batteries and measure the battery voltage at the battery terminals. If the voltage is less than 85% of the rated voltage, allow them to charge for 48 hours. 3. If the problem persists, replace the batteries.
What to do if the Ground fault trouble Earth yellow LED is on in System Sensor PDRP-1001 Control Panel?
If the Ground fault trouble Earth yellow LED is on: 1. Remove field wiring from the main panel and optional modules (if installed). Install a dummy ELR (4.7K for 24V systems; 2.2K for 12V systems). 2. Remove both battery leads. 3. If the trouble clears, connect one circuit at a time to pinpoint the problem. 4. If the trouble doesn’t clear, replace the circuit board.
Why are any of the right column red LEDs on System Sensor Control Panel activated?
If any of the right column red LEDs are on, it indicates a short on the initiating circuit wiring. Remove the field wiring and install an ELR. If the trouble clears, inspect for faulty or incorrectly wired devices.
What does it mean if any of the right column yellow LEDs are flashing on System Sensor PDRP-1001?
If any of the right column yellow LEDs are flashing: 1. Check TB4 for proper connections. 2. Remove the field wiring for the zone in trouble and install a dummy ELR (4.7K for 24V systems; 2.2K for 12V systems). If the problem persists, replace the circuit board. 3. Check for an ELR at the last device. 4. Check the field wiring.
How do I fix the AC Power LED always on issue on System Sensor PDRP-1001 Control Panel?
If the AC Power LED is always on: 1. Check TB2 for proper connections (TB3 for 4XB panels). 2. Remove all field wiring and install a dummy ELR at the output circuit. Check for supervisory voltage across it (normal -2.3 V). If the problem persists, replace the circuit board. 3. Remove the dummy ELR, reconnect the field wiring, and measure the voltage across the output (trouble -5V, short OV). 4. Check for an ELR at the last device. 5. Check the field wiring.
What causes a Municipal Box open circuit on a System Sensor PDRP-1001, and how to resolve it?
If there is a Municipal Box open circuit: 1. Install a dummy load if the Municipal Box option isn’t used. 2. Check the Municipal Box wiring.
Why is the yellow LED on the 4XTM System Sensor Control Panel on?
If the yellow LED on the 4XTM is on, move the Municipal Box disconnect switch SW1 up.
What does Micro Fail yellow LED on System Sensor PDRP-1001 mean?
If the Micro Fail yellow LED is on, the microprocessor is damaged. Replace the circuit board.
Why doesn't disconnecting the Municipal Box switch on 4XTM create a trouble on System Sensor PDRP-1001?
If disconnecting the Municipal Box switch on the 4XTM does not create a trouble, the jumper for optional modules isn’t cut. Cut the associated jumper OPT1 or OPT2.
