What to do if the Trouble Relay is active in UTC Fire and Security Controller?
If the Trouble Relay is active, it indicates that a monitored device in the system, including a ground fault, is in a fault condition. Use the front panel display/controls to view all points in alarm/fault and identify the faulted device. Then, repair or replace the faulted device as necessary.
How to fix digital inputs that are not responding on UTC Fire and Security DET-TRONICS 95-8533?
If digital inputs are not responding, here are a few things to check: - Ensure that P2 and P3 are fully inserted. - Use a voltmeter to measure input terminals with the contact closed to the input (it should measure 0 VDC when the input contact is closed, and approximately 23 VDC with the circuit open, with a 24 VDC input at the controller). - If the input does not respond to a contact closure, replace the module, verifying the response with EQ Safety System Software/textual display. - Also, verify the configuration, because the cause may be a configuration error or faulty wiring.
What to do if relay outputs are not responding to an output command in UTC Fire and Security DET-TRONICS 95-8533 Controller?
If relay outputs are not responding to an output command, it could be due to a bad relay channel, faulty output wiring, or user logic issues. Check that P4 and P5 are fully inserted. When the output should be energized, measure contact resistance using an ohm meter. Verify that the wiring from the output is not open. Using EQ Safety System Software, verify that the logic is trying to operate the channel.
What to do if serial links are not responding in UTC Fire and Security Controller?
If serial links are not responding, the issue could be faulty wiring, an incorrect serial link configuration, or the text display showing “Invalid Configuration”. Check that P8 and P9 are fully inserted. Verify that the communication LEDs are flashing. Ensure that the serial link configuration matches the host device. Verify that the wiring is not open or shorted.
Why is the Controller Power LED/ Text Display OFF on my UTC Fire and Security DET-TRONICS 95-8533 Controller?
The Controller Power LED/Text Display might be off because there is no power to the input. Measure the input voltage (18 to 32 VDC). Check that P1 is fully inserted. If voltage is present and P1 is fully inserted, replace the controller.
Why is the LON Fault LED lit on UTC Fire and Security DET-TRONICS 95-8533?
The LON Fault LED might be lit because the LON wiring is shorted or open. Check that P7 is fully inserted. Use the EQ Safety System Software to determine the location of the open or short via the LON Diagnostics screen. Use a multimeter to determine the wiring fault.
What to do if front panel pushbuttons are not working on UTC Fire and Security DET-TRONICS 95-8533 Controller?
If the front panel pushbuttons are not working, verify that power is present and P1 is fully inserted. Cycle power to the controller.
What does it mean if the text display indicates a RTC Fault on UTC Fire and Security DET-TRONICS 95-8533?
If the text display indicates an RTC Fault, it means there has been a power loss for more than 12 hours. Using the Safety System Software, execute “Set RTC” to download the current time into the Controller’s real-time clock. Alternatively, use the “Set Time and Date” menu in the Controller.
