Easichange Replacement for DETA 1115 Mains Powered Heat Alarm

The discontinued DETA 1115 was a mains‑powered heat alarm with a 9V backup battery, and easichange® now offer fully backwards compatible replacement that fit the original DETA 1100 series bases. The SBBRKHE is the direct replacement, designed to clip onto your existing mounting plate without needing an electrician.

Providing the same mains power and replaceable 9V battery, this alarm activates when temperatures rise to around 55°C, making it ideal for kitchens and garages where smoke alarms may be triggered by dust or cooking fumes. A central test/hush button makes upkeep simple, and its hardwired interlink lets all connected easichange® alarms sound together if one detects heat.
