STI polycarbonate protective cabinet

Product Overview

The A/C or A/C with heat versions of the STI Protective Cabinet allow fire alarm control panels to be protected from extreme temperatures and other conditions that require NEMA 4 protection. The extra large, super tough, see-through polycarbonate enclosure offers protection against vandalism, either accidental or intentional, as well as dirt, dust and grime.

Its size allows the enclosure to house significantly sized electronic devices with space to spare. This NEMA 4 Certified enclosure mounts on the wall enabling units to be protected in their designated location.

how it works

To help maintain the correct range of operating temperatures, the A/C or heating unit cycles as required and a fan runs continuously to sustain a uniform temperature inside the enclosure. The fiberglass A/C or heater contains an integral power supply and built-in condensate removal system. The cost effective, low maintenance, compact and lightweight A/C or A/C with heat unit does not require a compressor, fluorocarbons or filters and is externally mounted to minimize space intrusion.
