always wondered because of how low they are would it be able to pass the speed bump or will it scratch the front?
go to you local arts and crafts store they should have blank stamp material and carving tools or you could use a stencil .
Yes to the fire alarm and to monoxide alram. It was provided by an outreach program for seniors in my area, and I am thankful for that. I have a cell and no landline that I use. Didn't know anything about reverse calling except that if I call 911 and don't respond they call back.
I highly doubt that you will set the detector off with insense burning. I recommend that you leave the fire prevention equipment alone. Its put there for a reason. May save your life one day.
