A smoke detector that chirps constantly, fails to sound during a test, or triggers false alarms at random is more than a nuisance — it is a potential safety failure. A detector people learn to ignore because it false-alarms is functionally useless in a real fire. Our Luthuli Avenue electronics repair workshop in Nairobi diagnoses and repairs mains-powered and battery-operated smoke detectors, including interconnected multi-detector systems. Call 0723763173 to arrange a repair or home visit.
Smoke Detector Faults We Diagnose and Repair
- Chirping or low-battery warning that won't stop — battery terminal corrosion cleaning, battery holder replacement, and low-battery circuit repair.
- False alarms — ionisation chamber cleaning to remove dust and insect contamination on ionisation detectors; photoelectric chamber cleaning on optical models.
- Alarm not sounding on test — alarm sounder replacement and test circuit repair.
- Interconnect fault — wiring fault diagnosis and relay circuit repair on hardwired multi-detector systems.
- Mains-powered unit fault — power supply circuit repair and back-up battery replacement.
- Sensor cell replacement — on units where the sensing element has degraded beyond its service life.
When to Repair vs Replace
Smoke detectors older than ten years should be replaced regardless of apparent function, as their sensing elements degrade with age. For units within their service life, repair is the right choice. We will advise you honestly during assessment.
