How to Get the Most Out of Your Plenum Fire Alarm Cable Investment
Fire alarm systems are critical to ensuring the safety of your building and its occupants. And while the cable you use may seem like a small detail, it can actually play a big role in the performance and longevity of your system.

This is because the special insulation on plenum fire alarm cable will protect the cable from damage, even if it is exposed to high temperatures.
