## Questions & Answers

**Q: Will an st-622 unit fit into the base of an st-620 (which gave out after four years)?**
A: Yes

**Q: How do I stop it bleeping?**
A: If it has been set off by smoke and sounding continuously eg toast poke the bottom with a broom handle and that should reset it. If it’s bleeping every few minutes the battery is probably down and needs replacement- you may need a new unit as the battery itself may not be replaceable. Hope this helps

**Q: just  bought this alarm pressed test button in centre no bleep is it faulty**
A: It is only active when fitted to the ceiling mount. Test once mounted.

**Q: How do I test the battery?**
A: Press the big button in the middle of the alarm and it should bleep twice.
