Good morning all.

One of my schools has a Danfoss 841 School Bell fitted and it has recently given up and is currently running on battery back up ( manual ringing is driving the office staff mad ).
As a ‘one for one’ replacement is looking like £300 does anyone know of a possible cheaper equally reliable option.

Thank you very much.
Ben.

I doubt you'll get any other timeswitch/bellringer as good for less.

Hi matey
I had a similar problem with ours last week , so i switched it off at the mains for a day then put it back on and it worked fine part from re inputting times etc
But if you need to replace it (i couldnt find anything else to do the same job) , its just three wires like a plug so very easy [Like.png]

We used to use a Danfoss timer system, but we switched to our fire alarm. It turned out that our fire alarm panel could do more than just sound the alarms.

Just checked and we have a Danfoss timer for the school bells, it was integrated into the fire alarm system with a different bell sound [Like.png]
