01
Common symptoms
Door entry faults often look similar from the handset but have different causes. We test the signal path rather than replacing parts at random.
- Buzzer does not ring
- No audio or one-way audio
- Door release buzzes but does not open
- System works intermittently
02
What we may need access to
Depending on the fault, testing may require the affected handset, entrance panel, controller or power supply, electric lock and sometimes another known-working flat or user point.
03
When replacement is better
Replacement usually becomes the better option when equipment is obsolete, water damaged, repeatedly failing, badly altered or no longer suitable for the way the building is used.
