Sprinkler Fire Alarm Sign is an NFPA 13-compliant red powder-coated 18-gauge aluminum (.040 aluminum) sign instructing a building's occupants to call for help when a fire alarm bell rings. This 6 in. (152.4 mm) sign reads 'Sprinkler Fire Alarm - When Bell Rings Dial 911'‚ in large white letters.
This signaling system sign is required for structures with a central station, auxiliary or remote station, or a protective signaling system in addition to a local alarm.
The sign is nice quality aluminum and holds its shape better than the cheap plastic signs. Easier for install as you can tighten it securely without worrying about cracking the sign.
