SITERWELL Smart Thermostate C-Wire Connector
Built different. Certified to prove it.
From 10-year sealed batteries to whole-home interconnection — every spec exists to protect your family, not just pass a spec sheet.
10-Year Battery Life
Sealed lithium — zero replacements. Install it and protect your home for a full decade without touching a battery.
Whole-Home Interconnect
Trigger one alarm, hear all of them. Up to 18 units linked wirelessly — critical when you're asleep upstairs.
Photoelectric Sensing
Detects slow-smoldering fires earlier than ionization tech — the kind that start overnight and spread silently.
Dual Power (AC + Battery)
Hardwired with automatic battery backup. A power cut doesn't mean your home goes unprotected.
