8. Vianmääritys
If the alarm bell is not functioning as expected, perform the following basic checks:
| Ongelma | Mahdollinen syy | Ratkaisu |
|---|---|---|
| Bell does not ring. | Ei virtalähdettä. Väärä voltage. Löysä johtoliitäntä. Viallinen yksikkö. |
Check if 24V AC power is being supplied to the unit. Verify the power supply is 24V AC. Tarkista ja kiinnitä kaikki johdotusliitännät. Jos kaikki tarkistukset epäonnistuvat, laite saattaa olla viallinen ja se on vaihdettava. |
| Bell rings continuously. | Constant power supply. Wiring short circuit. |
Ensure the control circuit is correctly switching the 24V AC power. Check wiring for any short circuits that might be supplying constant power. |
| Ääni on heikko tai vääristynyt. | Teho ei riitä. Estäminen. Sisäinen vaurio. |
Verify the 24V AC power supply is stable and sufficient. Check for any physical obstructions around the bell mechanism. If persistent, the unit may have internal damage. |
If troubleshooting steps do not resolve the issue, contact qualified service personnel or the product supplier for assistance.
