CERTIFICATIONS
With the exception of the MS-80 piezo sirens, all the sirens shown above are IP54 certified, which means they have passed –40°C to +125°C temperature tests, are flame retardent and waterproof.

• The internal battery of backup sirens typically lasts 2-3 years. Heat and other environmental factors ultimately determine battery life. The internal battery cannot be replaced, but the siren should still continue operating normally without it, although there would be no "backup" functionality. • Only the KB-series comes standard with keys. We cannot make spare keys, so please keep your keys safe in separate locations.
