A great suggestion. I have actually been to the firehouse myself, as it is a couple of blocks from my house, and was advised to contact 3-1-1, a branch of the 9-1-1 service for City of Dallas, to have this "automated" information for the relay entered, and was told that the City will NOT add information like that about an animal. A convalescent or disabled person, yes. An animal, no. Naturally, I realize that the saving of lives is and should be top priority, but come on ... it's four words on a CRT that pops up on a screen as the unit is en route to my home ablaze. Regardless, trying to take advantage of modern technology to circumvent an archaic systematic flaw. Naturally, I've got smoke detectors in the house; actually hardwired ones, not just battery powered ones. I also have ADT home security. However, the smoke detectors are not part of the ADT system. Therefore, someone has to be in the house to push the FIRE button on the control panel to summon fire/rescue personnel. In that perfect situation, my dogs' safety is in my hands, and I've got it covered. Otherwise, ....
SO....back to the project....I would have the system set to call up to four numbers, including my own, to alert that is a fire in the house. Perhaps a human voice can spur the fire department to take action.
