Summary
This article provides troubleshooting for Altronix connected devices.
Common Symptoms
| Symptom | Possible Cause | Recommended Checks |
|---|---|---|
| No power output | Loss of AC input, blown fuse, tripped breaker, or disconnected transformer wiring |
|
| Low or unstable voltage output | Overloaded power supply, excessive current draw, voltage drop, or undersized wire gauge |
|
| Output shuts down intermittently | PTC protection tripping from short circuit or overcurrent condition |
|
| Reader or controller offline | Voltage drop, RS-485 communication issue, loose power connection, or reversed polarity |
|
| Lock not energizing | Incorrect relay wiring, insufficient current, failed relay output, or wrong lock voltage |
|
| Lock remains energized continuously | Relay wired to incorrect contact, stuck relay, or incorrect fail-safe/fail-secure configuration |
|
| Fuse/PTC repeatedly trips | Downstream short circuit, damaged lock, or excessive startup current |
|
| Fire alarm release not functioning | Incorrect FACP DIP switch settings, missing FACP trigger wiring, or improper supervision |
|
| LEDs off on module | No input power, failed board, loose wiring, or blown fuse |
|
| Batteries not charging | Failed batteries, loose battery leads, or charger fault |
|
| Devices rebooting randomly | Power sag under load, insufficient supply capacity, or battery fault |
|
| Door forced/held events causing reader issues | Shared power instability, grounding issue, or output overload |
|
| Access controller intermittently disconnects from network | Voltage instability, overloaded PSU, or poor grounding |
|
| Maglock weak or buzzing | Insufficient voltage/current, long cable run, or poor termination |
|
| Strike clicks but door does not unlock | Mechanical preload, incorrect strike type, or low voltage at strike |
