This air conditioned enclosure allows alarm control panels to be protected from extreme temperatures or other areas requiring NEMA 4 protection. The extra large, super tough, heavy-duty metal enclosure offers protection against vandalism, either accidental or intentional, as well as dirt, dust and grime. Unlike competitor models, this NEMA 4 Certified enclosure has a clear window allowing the unit within to be quickly identified and includes two key locks for added security. To help maintain the correct range of operating temperatures, the air conditioning unit cycles as required and a fan runs continuously to sustain a uniform temperature inside the enclosure. The steel (with baked enamel finish) air conditioner is cost effective, low maintenance, compact and is externally mounted to minimize space intrusion.
