door bell for warehouse

[egginyourface]

evening all,

ive been asked to fit a bell for warehouse. I went to wholesaler and they gave me a fire alarm bell which runs on 24volts and a chunky 12 volt transfomer. I rigged it up temporarily and it didnt sound that great.

Is it bettter i use a 24 volt tranny

or

can anyome reccomend a good bell and tranny


thanks in advance

which numpty of a wholesaler gave you a 12v tranny to run a 24v bell? that's like plugging a 240v drill into a 110v site tranny. (.i know the plugs are different but a plumber would try to make it fit). go to an alarm suppliers and buy a 12v bell or siren.

 

[i=p/u]

well why use a 12v on a 24v bell??? i dont know the outcome??? but someone will

 

[i=p/u]

can you not get 24v tansformer, i have one of them bells lying in garage, and says 24v, i want to hook it up to phone in house and bell at garage

re' last post. a siren is d.c. so you'd need a 12v d.c.PSU.

this wholesaler is quite reliable so took there word for it. Its quite a chunky tranny, full of electronics dc etc

Should i just get a 24 volt dc tranny?

 

[egginyourface]

its a 90db bell

 

[telectrix]

if you're getting 12v dc out, then get a 12v siren as in intruder alarms.

 

[alarm man]

if you're getting 12v dc out, then get a 12v siren as in intruder alarms.

as tel says,get a 12v internal intruder alarm siren,cheaper than a 24v psu

That's not too bad, some of my wholesalers only have one brain shared between dozens of sales staff.

Search for underdome door bell on the TLC website, that little bell is quite noisy, and 12V

 

[telectrix]

and mount it out of the way or tomorrow it will be dangling from the forks of a forklift truck. talk about wholesalers being short of brains. some forklift drivers are cretins with their brains removed.

its horses for courses a warehouse could be 4mtrx5mtr or 400mtrx500mtr noise levels may comeinto it as well Cant you fit a car horn they are 12v

 

[egginyourface]

the warehouse isn't that big but has loads of compartments etc. The bell im replacing was supposed to be quite loud and it only worked on a little 12v tranny.

Whats the recommended db.

 

[telectrix]

nothing recommended for door bells. it's not a fire alarm, is it? just get something to wake the buggers up.

 

[egginyourface]

would this work with any 12v tranny
