- Two boxes on a post. Equipment box and solar box, at the road where the copper comes in.
- No site power. Solar with battery backup.

Questions
Is the whole box certified? No. The router, line computer, I/O and solar charge controller are Class I Div 2 certified. The phone-line gateway and the batteries carry no hazardous rating: the gateway sits in the NEMA box under the NEC 501.150(B) provision (no make-and-break contacts), and the assembly needs your site's evaluator to accept it. If they won't, an explosion-proof enclosure for the gateway is available.
Who does the fire alarm side? A licensed fire alarm partner. We don't install or monitor fire alarms.
