This 6-inch fire alarm bell from Safeguard Supply is loud – we're talking over 85 decibels of crisp, attention-grabbing ring that cuts through noise like a hot knife through butter.
It runs on 12V DC, so you can wire it into all kinds of systems – fire alarms, doorbells, school bells, or industrial signaling setups.

It's made from industrial-grade ABS, so it's resistant to oxidation and chemicals, making it suitable for demanding indoor environments like warehouses, manufacturing facilities, and workshops.
If you're hard of hearing or work in a noisy location, replacing your standard doorbell chime with this bell makes sure you never miss a visitor or delivery.
Installation is flexible – wire it into any device that outputs 12V DC, or use it with a form C relay and external power.



Backed by a 1-year warranty from a US veteran-owned small business.
Dependable, versatile, and definitely not subtle.
