I can't hear most smoke detectors because the tone frequency is too high.

NFPA recommends a tone of 520hz. Anyone know what brands might qualify?

Thanks in advance.

1. There are quite many offered

in a google search for 520hz smoke detector, ranging from $49-$225+
Not recommending since there are different applications, etc only you know

2. Not answering your question as asked, but have you considered a smoke detector with a

verbal/spoken alarm?

We recently (~5 years ago) replaced all of ours with a smoke/carbon monoxide detector by Kidde (don't know the model number off the top of my head) and it alternates beeps with a slightly robotic female voice "FIRE! FIRE! FIRE!" when it goes off from smoke or "DANGER! DANGER DANGER!" for carbon monoxide.

3. Red Cross

Is offering smoke detectors. They put mine in free, 10 year, no battery replacement.

Carbon monoxide detectors at your local fire department. They should be able to answer.

4. My dog and cat freak out when smoke alarm goes off. A loud spoken word, only, would be nice.

I'm a light sleeper and don't need a piercing alarm. Or so I think.

5. There are some that can be hocked to...

...bright flashing lights or for your bedroom, a vibrator pad like an alarm clock. Sound is NOT the only alternative for an alert.
