## Questions & Answers

**Q: Do these fire alarms activate eachother when one goes off? Need one inside sound proof room and one outside thanks**
A: Good Morning, 
These are standalone alarms so they will not link in with any other unit. 
If you are looking for units that will trigger each other in the even of a fire, then our Pro Connected range will be more suited. 

Many Thanks,
Gemma

**Q: Are these suitable for the new Scottish legislation**
A: Good Morning 
The TST-625R alarm is a standalone unit and therefore cannot be interlinked with any other product. 
If you are looking for units which can be interlinked with each other then I would recommend the FireAngel Pro Connected range. 
Many Thanks
Gemma

**Q: Will this fit the baseplate for the old si-601?**
A: Yes, this unit will fit onto your existing base plate. 
Many Thanks
Gemma

**Q: How loud is the alarm in term of db ?**
A: DB unknown but very loud and as loud as any other alarm I've had over the last 40 years.
