315 MHz Sirens and 433 MHz Sirens

Some of our systems use sirens that operate on a 315 MHz frequency, and others use sirens that operate on a 433 MHz frequency. 315 MHz sirens will not work with systems that have 433 MHz sirens, nor vice versa.

If you are unsure whether your panel and/or sirens use 433 MHz radio signals, you can check by looking for the "433M" sticker. This will be on your panel and on your sirens, if they use 433 MHz.
