Shown below are two examples of fire alarm control panels protection design using the best surge protector options.
These protection networks are retro-fit installations. The designs provide surge suppression for the existing fire alarm panel power and communication lines.
All modes of the power supply feeding these two alarm systems are protected individually prior to entering each panel.
All communication circuits feeding these two examples are also individually protected prior to entering each alarm panel.
For any electrical power or communication signals to reach the alarm control panels circuits... or leave from the control panel circuits... they must pass through the surge protection devices first.
The SPDs protectively isolate the fire alarm control panels. This protects them from the electrical systems damaging transient voltage activity.
The above photo shows surge protectors installed in a flush-mounted enclosure. The protected fire alarm system panel is below.
Above photo provides a closer look at the surge protector installation for both power (black) and data lines (gray).
In this photo, you can see a slightly different retro-fit install for both power (black) and data lines (gray) protection.
Besides the individual fire alarm control panel SPDs, additional devices for other electrical panels and/or disconnects within the facility should be carefully considered.
Additional SPDs placed upstream from the fire alarm panels create a layered or cascade protection approach. This is highly recommended especially on the power side.
A layered or cascade protection approach is recommended by the IEEE. This provides a best practice when protecting sensitive electronics and critical equipment.
Protecting against large transients, especially lighting generated events, robust surge suppressors with high kA ratings, true all-mode-protection design and circuit encapsulation can provide a distinct advantage over competing devices.
Our line of SPDs are specifically designed for applications and protection needs of the fire alarm industry. Our top of the line Advantage® Series are high quality, high performance devices. These devices employ True-All-Mode Protection and use a multi-stage, hybrid network design.
All surge suppression devices shown are High Quality, High Performance units and come with a 25 Year No Hassle Warranty.
