Monitored HomeKit smoke/fire detection

I’m in the process of setting up my smart home using HomeKit and am ready to commit to a security system but am having trouble finding a comprehensive, monitored system that includes smoke and fire detection. Thus far I have installed an ecoBee thermostat and am happy with it, but ecoBee’s solution for fire monitoring is to have an audio monitor that alarms for the T3 frequency of conventional smoke detectors. Although my insurance company confirms this will still qualify for the discount on homeowners insurance since it’s monitored through Haven, I don’t particularly like the extra step where a system could fail, and would prefer a monitored system directly to smoke detection. Does anyone know of such a system or if one is forthcoming?
