16V Transformer for a 24V Fire Bell - Possible?

I'm trying to install a fire bell as our house doorbell and I had a question about the power being supplied versus what the bell device wants. Currently, I have a 16V transformer providing power for a traditional doorbell. The fire bell I purchased is a Wheelock MB-G10-24. It indicates that it is polarized for DC and that the input voltage is 24.

Is it safe to connect the bell to a 16V power supply if it is rated for 24V? I would be fine if the bell would draw less power, possibly making the bell a little quieter, but I don't want to have a fire risk if the bell is going to try to force 24V from a 16V transformer.

The 16v transformer will give you 22v+ when rectified so should work and they are often a volt or two over the 16v.
Probabally close to 24vdc.

Wow! You guys are fast and awesome! I'll get everything wired up and see if I can upload a video of it in action. I might need to muffle it a little bit if it's too loud :)
