Am working at a local school installing CCTV system. The headmaster collars me today and asks me whether I can automate the bell ringing system and puts in my hand a leaflet on the Danfoss 841.
I had a quick look at the current system, which is a single push button in the school hall that rings 5 x 240V bells in the corridors. The 841 does not have the ability of pulsed output but the 842 is 2 channel, but has the ability of pulsed output.
Am I correct that for bells, you require a pulsed output???
Anyone point me in the direction of a cheap supplier for these.
Thanks in anticipation.
