Smoke Alarms & Detectors

Smoke alarms sense smoke and sound a loud warning, and include mains and battery alarms for homes, wireless Ajax detectors and addressable detectors for fire alarm panels. Start with where the device reports: to its own sounder, to other alarms in the home, or to a panel.

Alarm, wireless detector or addressable head

Smoke and heat alarms sound locally: the Aico Ei146e interconnects by hardwire or RadioLINK, the Ei650iRF, Ei630iRF and Ei660iRF by RadioLINK+, and the Ei650i is standalone. Ajax FireProtect, Hikvision AX-Pro, Pyronix and Texecom detectors report to their own security hub. Nittan Evolution and C-TEC CAST heads connect to an addressable fire panel loop.

Optical, heat or multi-sensor

Optical alarms with a photoelectric chamber, such as the Aico Ei146e and Ei650i, suit bedrooms, halls and landings. Heat alarms and detectors, fixed-temperature or rate-of-rise, suit kitchens and garages where fumes or dust would trouble a smoke head. Multi-sensor models such as the Aico Ei660i and C-TEC C4414 combine optical and heat sensing.

Power

Battery models with a sealed 10-year lithium cell, such as the Aico Ei650i and Ajax FireProtect 2 SB, avoid battery changes. Mains models with backup, such as the Aico Ei146e and Espire ES1SLV, suit new-build and rewired homes.

Standards & compliance

Smoke alarms listing EN 14604 include the Aico Ei146e and Ei650i, Espire ES1SLV and Mercury 350.126UK, and heat alarms listing BS 5446-2 include the Aico Ei144e, Espire ES1HRV and Mercury 350.130UK; the Aico Ei660i and Espire ES1MUL list both. Among detectors, the Nittan EV-P and C-TEC C4416 list EN 54-7, the C4403A1R lists EN 54-5, and the C4414 and Nittan EV-PH list both. Where a product lists no standard, check its documentation.
