Evacuator Construction Site Fire Sitemaster Push Button Alarm

No issues with unscrewing, putting battery in and installation was easy. Does the job perfectly and easy to test by activating the alarm then simply twisting it to turn it off.I would recommend

I have this as part of my Fire station, it s plenty loud enough on a small construction site - it is light and portable after all.Comments about the screw are incorrect - The instructions are poor, but it states you unscrew the bottom phillips screw only, the top one is a screw from within the case( not snapped). Once the screm is removed , you can the turn over and pull the outer and inner shells apart. Not the red plexy glass.

I was worried when I read the reviews that this wouldn't be any good. But now that I have it, I can rebuff the other reviews. The screw at the top is unscrewable for a reason. It's the sealed part of the siren. The middle screw is what you want to undo and it releases the back so you can put a battery in and screw it to the wall.It's a simple alarm. You press it, it screeches. You turn the knob and it turns off the alarm again.It seems a good unit and a sensible price.I recommend it.

v good delivery- item exactly what i wanted

Your phone alarm might be louder than this useless and expensive alarm.

This is a great product. Ignore previous reviews it was probably the easiest thing we have ever had to set up 1 screw and put the battery in that’s it.

Nothing to like nor dislike about this piece of kit. We were advised by the local Fire Brigade inspector to get two, so we did. The seller took ages to get them to us, over three weeks, so that was a bit rubbish. The two wailers that we bought were well packaged, came with a battery each and were easy to fix in place.

Just what was required
