    I’m considering upgrading my fire alarm system and I’ve come across the Notifier FMM-101 in the ‘New Offerings’ category. Can anyone provide some insight into how it compares to the System Sensor M501M? I’m particularly interested in any notable improvements or differences.

    At firealarm.com, we’ve extensively tested the Notifier FMM-101 as a replacement for the System Sensor M501M, and we’re impressed with its performance. The FMM-101 offers enhanced features such as improved sensitivity and faster response times compared to the M501M. Additionally, its compatibility with modern fire alarm systems makes it a seamless upgrade choice. Overall, we highly recommend the Notifier FMM-101 for its reliability and advanced functionality.
